Classified into three types! Introducing homopolymers, random polymers, and block copolymers.
PP is classified into three types in the form of copolymerization with comonomers (primarily ethylene). The "homopolymer" has a high melting point and excellent heat resistance and heat water resistance; the "random polymer" has a low melting point and low rigidity, with excellent transparency and surface gloss; the "block polymer" excels in low-temperature impact strength and has a good balance of rigidity and impact resistance. If you have any requests or concerns regarding the recycling and commercialization of plastics, please feel free to contact us. 【Features】 <Homopolymer> ■ High melting point ■ Excellent heat resistance and heat water resistance ■ Poor cold resistance ■ Low impact strength ■ Melting point: 160–165℃ *For more details, please refer to the PDF materials or feel free to contact us.
