2019.08PP is a semi crystalline material that is harder and has a higher melting point than PE. Due to the brittleness of homopolymer type PP at temperatures above 0C, many commercial PP materials are random copolymers with 1-4% ethylene added or block copolymers with higher ethylene content. Copolymer type PP materials have lower thermal deformation temperature (100 ℃), low transparency, low glossiness, and low rigidity, but have stronger impact strength. The impact strength of PP increases with the increase of ethylene content. Characteristics of PP granulator: 1. Good flowability, but

2019.08Due to its high shrinkage rate, universal PP often leads to product defects, such as poor dimensional stability, easy warping and deformation, and its poor toughness makes its low-temperature brittleness particularly prominent. In order to expand the application field of PP, it is necessary to conduct modification experiments and strive to find methods to improve its performance. Experimental Ethylene Octene Copolymer - Polyolefin Elastomer (POE) and β The nucleating agent is a toughening agent, and environmentally friendly color mixed inorganic pigments with high temperature resistance and excellent light and weather resistance are selected as the colorant. A new type of magnesium salt whisker is used as

2019.05PP granulator features polypropylene, English name: Polypropylene, Japanese name: ポリププピレンン Molecular formula: C3H6nCAS Registration No.: 9003-07-0 Abbreviation: PP is a thermoplastic resin made from propylene polymerization. According to the methyl arrangement position, it is divided into three types: isotactic polypropylene, atacticPolyPropylene, and syndiostaticPolyPropylene. PP is a semi crystalline material that is harder and more
