Diving into Linear Low Density Polyethylene (LLDPE): Understanding Its Properties and Manufacturing (2023-2034)

In the world of plastics, LLDPE stands tall for its remarkable toughness, enabling the creation of thinner yet robust films. Not to be confused with its cousin LDPE, or Low Density Polyethylene, LLDPE boasts a unique structure with numerous short branches. This structural advantage allows its chains to glide smoothly during stretching, preventing entanglement—a common issue with LDPE due to its long branching chains. The result? LLDPE offers superior tensile strength, along with heightened impact and puncture resistance compared to LDPE. So, when it comes to durability and performance, LLDPE takes the lead, making it a top choice for various applications where strength and resilience are paramount.

Introduction

LLDPE or Low-Density Polyethylene is a lightweight, flexible plastic. LLDPE stands out among polyethylene variants due to its semi-crystalline nature, featuring linear molecular chains with short branches. Unlike LDPE and HDPE, these linear molecules exhibit slower tangling. LLDPE is synthesized using one of three alpha-olefin co-monomers, namely octene, hexene, or butene, each influencing its properties differently. Octene contributes long branch chains, offering superior performance. Hexene strikes a balance between octene and butene, providing a cost-effective way. Butene, the most commonly utilized co-monomer for commodity plastics due to its affordability, features the shortest branch chains. Moreover, LLDPE properties can be further tailored by blending it with other co-monomers, with combinations of butene and hexene being particularly prevalent in practice.

LLDPE’s properties include:

Puncture-resistant: making it highly resilient against sharp objects or external forces that could cause punctures or tears.

Good flexibility: its ability to adapt to different shapes or movements without losing its structural integrity.

Resistant to oxidation: LLDPE has the capability to withstand oxidation, which is a chemical reaction involving oxygen that can degrade or weaken materials over time. Resistance to oxidation ensures the material's durability and longevity.

Excellent barrier properties: LLDPE has the ability to prevent the passage of gases, liquids, or other substances through it. Materials with excellent barrier properties are effective in containing or isolating substances, protecting them from external factors.

High impact strength: LLDPE can withstand sudden or intense impacts without breaking or shattering, indicating its resilience to mechanical forces or collisions.

Good environmental stress cracking resistance: LLDPE is resistant to cracking or fracturing when subjected to stress from environmental factors such as temperature variations, chemical exposure, or mechanical loading. Low Water Absorption: With its low water absorption rate, LDPE remains unaffected by moisture, making it suitable for applications where exposure to water or humidity is common.

Low Cost: Perhaps one of its most appealing attributes is its affordability. LDPE offers a cost-effective solution without compromising on performance, making it a preferred choice for a wide range of applications across industries.

LLDPE exhibits distinctive melt flow characteristics, making it suitable for processes like blow molding, film extrusion, and injection molding. Film extrusion, particularly, dominates LLDPE processing. It's worth noting that LLDPE's semi-crystalline nature contributes to its high shrinkage rate, whereby the material occupies more volume in its molten state than when solid. Overall, LLDPE's versatile production methods and unique properties make it a go-to material for various applications in industries ranging from packaging to automotive and beyond.

Manufacturing Process

The manufacturing process consists of four primary phases:

(1) Polymerization

(2) Devolatilization

(3) Distillation

(4) Finishing

Polymerization:

Ethylene and 1-octene initially undergo treatment in fixed-bed adsorption systems to remove water, oxygen, and other polar impurities that could potentially hinder the catalyst. After purification, the monomers are mixed with a polymerization solvent comprising a blend of C8-C9 paraffins. This mixture then enters the first of two consecutive continuous stirred tank reactors (CSTR), where polymerization occurs.

The polymerization process happens adiabatically in the liquid phase, with hydrogen acting as a molecular weight regulator. These steps ensure impurity removal and create ideal conditions for controlled and efficient polymer production in the liquid-phase reactors.

Devolatilization & Pelletizing:

The polymer solution exiting the second reactor enters an adiabatic flash vessel, where pressure reduction causes volatile elements, mainly unreacted ethylene, to vaporize. The concentrated polymer solution then undergoes devolatilization to remove residual monomers. The separated volatile components are cooled and sent for distillation, while the polymer proceeds to finishing. The devolatilized polymer is fed into an extruder to incorporate additives and pelletize the polymer, resulting in the final product being transferred to blending and storage.

Raw Materials Recovery:

The volatile effluents from devolatilization, containing unreacted monomers and solvents, undergo purification through distillation columns to recover these components and eliminate impurities, refining the final product.

The manufacturing process of LLDPE (linear low-density polyethylene) by Dow Chemicals involves a combination of polymerization techniques. Here is the brief overview of the LLDPE production process:

Monomer Preparation:

The first step in LLDPE production is getting the building blocks ready, called monomers. Unlike LDPE which uses only ethylene, LLDPE is made by combining ethylene with another molecule called a comonomer. Common comonomers include 1-butene, 1-hexene, or 1-octene. Adding this comonomer creates branches in the LLDPE structure, which give it special properties different from LDPE.

Polymerization:

Dow uses various polymerization techniques to produce LLDPE.

Solution Polymerization

Monomers and a catalyst system dissolved in a solvent, it's all stirred together in a reactor under carefully controlled temperature, pressure, and mixing. This controlled environment triggers a chemical reaction called polymerization, with catalysts, which often are Ziegler-Natta or metallocene catalysts.

Gas-Phase Polymerization

For gas-phase production, the reaction happens in a special reactor with a constantly moving bed of particles. These particles may hold the catalyst system (like a supported catalyst or a metallocene one). The mixture of monomers and catalyst is fed into the reactor, along with precise controls on temperature, pressure, and how long the ingredients stay inside (residence time). The heat from the reaction itself helps keep the process going.

Product Finishing:

After the LLDPE is polymerized completely, it's time to collect it from the reactor.  This raw material, called resin, might go through some finishing touches to get the exact properties needed. This involves removing any trapped gas (degassing), shaping it into pellets (pelletization), and additive incorporation.

Borstar, a pioneering multi-modal patented technology employed by Borealis for PE and PP production, represents a significant advancement in process technology. Borealis is actively commercializing the latest iteration of Borstar, including Borstar PE 3G, and continues to innovate within the Borstar framework. These advancements enable flexible polymer design, ranging from bi-modal to multi-modal PE/PP resins, and contribute to the development of a diverse range of new plastics.

The Borstar polyethylene (PE) method enables the production of a wide range of bimodal and unimodal LLDPE, MDPE, and HDPE products. This method combines a loop reactor and a gas phase reactor to form Borstar PE. PE with densities ranging from 918 to 970 kg/m3 and melt flows from 0.1 to 100 can be manufactured using this process. While single-site catalysts will be utilized for PE processing in the future, Ziegler-Natta catalysts are currently employed.

A mixture of propane diluent and catalyst is injected into a small pre-polymerization reactor, where pre-polymerization takes place. The resulting slurry is then fed into the loop reactor, operating under supercritical conditions at temperatures of 75–100 °C and pressures of 55–65 bar, to produce higher density and lower molecular weight components of bimodal polymers. Afterward, diluent and unreacted materials are removed from the polymer in a flash tank.

The loop reactor and gas phase reactor operate independently, allowing for easy regulation of reactor conditions and flexibility in processing various products. In the fluidized bed gas phase reactor, polymerization continues, producing a homogeneous polymer on the same catalyst particles. Operating at temperatures between 75 and 100 °C and pressures of 20 bar, this reactor introduces fresh hydrogen, ethylene, and comonomer to form high molecular weight components and broaden the molecular weight distribution (MWD), enhancing the polymer's strength.

The production rate ratio between the reactors can be adjusted to achieve desired product qualities. Finally, hydrocarbon residues are removed, and the polymer powder is extruded to obtain the final product.

NOVA Chemicals use the SCLAIRTECH method on the other hand. The SCLAIRTECH technology method produces a wide spectrum of linear polyethylene (PE) products, including linear low, medium, and high-density grades with narrow to broad molecular weight distribution. The most effective PE swing method enables cost-effective production throughout the whole range of PE grades from a single train.

The process utilizes a reactor fed with a solution containing ethylene and a co-monomer, such as butene-1, octene-1, or even a combination of both. The short residence time (under 2 minutes) allows for a highly flexible system in the solution phase. This translates to quick transitions between producing different grades of the final product, making it adaptable to diverse market needs.

High conversion rates within the reactor maximize output and prevent uncontrolled reactions. A hydrocarbon solvent keeps the reaction mixture in solution while facilitating heat removal. This solvent is then efficiently recycled back into the reactor. Finally, the molten polymer exits the system and is shaped into pellets using a conventional extruder and pelletizer.

The Spherilene method, developed by LyondellBasell, employs a gas-phase reactor in its proprietary technology. The LyondellBasell Spherilene process encompasses a fluidized-bed, gas-phase approach for manufacturing polyethylene (PE) products across all densities, spanning from linear low density (LLDPE) to medium density (MDPE) and high density (HDPE). This technology's versatility, demonstrated by its extensive range of grades, empowers licensees to effectively navigate the continually evolving polyethylene markets well into the future.

The core of the Spherilene technology lies in its simple design with just one reactor and a recirculation system. This setup is surprisingly versatile, capable of producing a wide range of polyethylene (PE) products with melt indices between 0.01 and 100 g/10 min and densities spanning 0.918 to 0.965 g/cm3. This technology, using Avant Z Ziegler and Avant C Chromium catalysts, can create various single-modal (monomodal) products like LLDPE film, HDPE for injection molding, and MDPE for rotomolding and textiles.

Spherilene stands out for its operational stability, leading to high reliability when paired with the consistent performance of Avant catalysts.  A unique reactor outlet mechanism efficiently extracts product with minimal gas contamination.  Unlike competing technologies, Spherilene allows for start-up with Avant Z catalysts without needing a pre-existing polymer seed bed.
