Degradable materials and non-degradable materials?

What are non-degradable plastic products?

The main raw materials of non-degradable plastic products are polyethylene and polyvinyl chloride, which are often used to pack other items and are indispensable items in people's daily lives. They are widely used because of their cheapness, extremely light weight, large capacity, and easy storage. The degradation cycle of plastic bags is extremely long. Due to the particularity of their materials, it takes about two hundred years to degrade.

What are degradable plastic products? Unilong's Degradable materials are mainly based on plastics, adding photosensitizers, modified starch, biodegradants and other raw materials. These raw materials reduce the stability of traditional plastics and accelerate their degradation in the natural environment to reduce pollution to the natural environment. According to different degradation methods, they can be divided into biodegradable materials, photodegradable materials, thermal degradable materials and mechanical degradable materials. Common degradable materials include PCL, PLA, PBAT, PBS, etc.

What are polymeric microspheres?

As facial and body fillers become more and more common in the medical beauty industry. I believe everyone should have heard of this product - PCL Microspheres

How Ploycarprolactone works

Ploycarprolactone is a medical-grade polymer that can be completely absorbed by the human body. It is both biocompatible and biodegradable. Poly(ε-caprolactone)CAS 24980-41-4 can achieve the effect of natural skin tightening by stimulating the regeneration of its own collagen.

Summary of PCL's effects:

1. Lifting and firming, promoting collagen proliferation, removing wrinkles and beautifying the skin;

2. Restore skin elasticity, replenish hyaluronic acid lost by the human body due to aging, relieve wrinkles, and resist aging;

3. Repair factor ingredients promote tissue cell regeneration, improve dull skin tone, and make the skin shiny and bright;

4. Maintain cell moisture, so that the skin absorbs and stores more moisture, and moisturizes the skin for a long time;

5. Prevent skin aging and pigmentation, reduce the formation of melanin, and achieve the effect of whitening and lightening spots

Unilong currently studies two specifications of Polycaprolactone Powder. The first type of PCL microspheres are 20-60 um in size, because phagocytosis does depend on the size of the microspheres. The smaller the particles, the faster the phagocytosis and the higher the degree of inflammation. The second type is soluble Polycaprolactone Powder that can be directly dissolved and used. If you want to know more about PCL, please feel free to consult Unilong!

What is polylactic acid (PLA)?

Polylactic acid (PLA) is a new type of biodegradable material, made from starch raw materials from renewable plant resources (such as corn). Polylactic acid is a pollution-free, biodegradable product. Next, Unilong will introduce the degradation stages of PLA and the advantages of PLA:

Degradation stages: 1) First, pure chemical hydrolysis into lactic acid monomers; 2) Lactic acid monomers are degraded into carbon dioxide and water under the action of microorganisms. Food cups made of polylactic acid can be completely degraded in just 60 days, truly achieving both ecological and economic effects.

Advantages:

Adequate sources of raw materials The raw materials for the production of polylactic acid are renewable resources such as corn, without the use of precious natural resources such as oil and wood, which will play a very protective role in the increasingly depleted oil resources.

Superior physical properties Polylactic acid is suitable for various processing methods such as blow molding and thermoplastics. It is easy to process and has a wide range of applications. It can be used to process various plastic products, packaged food, fast food lunch boxes, non-woven fabrics, industrial and civilian fabrics from industry to civilian use.

What are the advantages of PGA polymer?

The advantages of PGA polymer include its biodegradability, high strength and flexibility, and its compatibility with human tissue.

PGA polymer is able to break down naturally in the body, making it an ideal material for medical applications such as sutures and tissue engineering. It also has a high tensile strength and flexibility, allowing it to be used in various manufacturing processes.

Additionally, Unilong's PGA polymer is highly compatible with human tissue, reducing the risk of rejection or other adverse reactions when used in medical implants.

Poly(L-Lactic Acid) PLLA CAS 26811-96-1

Poly-L-lactide (PLLA) is the product resulting from polymerization of L,L-lactide (also known as L-lactide). Progress in biotechnology has resulted in the development of commercial production of the D enantiomer form. Polymerization of a racemic mixture of L- and D-lactides usually leads to the synthesis of poly-DL-lactide (PDLLA), which is amorphous. Use of stereospecific catalysts can lead to heterotactic PLA which has been found to show crystallinity.

ULI-ECO provides PLLA is an important biodegradable polymer material, which is characterized by non-toxic, non-irritating, biodegradable and absorbable, high strength, good plasticity, and easy processing and molding. The degradation period is 2~12 months. The degradation period can also be changed according to the addition of modifiers. PLLA is decomposed by enzymes in the living body, and finally forms carbon dioxide and water, which has good bio compatibility.
