Applications of GRELA 2nd Generation Catalyst

1.Polyolefin Production

Mainly used in industrial-scale production of high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE), and isotactic polypropylene (iPP).

[uivchem]

The Grela 2nd Generation Catalyst (CAS 502964-52-5) is a high-performance catalyst developed in recent years, primarily used in olefin polymerization reactions (e.g., polyethylene and polypropylene production). It serves as a replacement for traditional Ziegler-Natta (Z-N) catalysts and certain metallocene catalysts, particularly excelling in improving polymerization efficiency, stereoregularity, and copolymerization performance.
