Rod
It is a semi-crystalline material. It is harder than n and has a higher melting point. Since the homopolymer type is very brittle when the temperature is above ℃, many commercial materials are random copolymers with ~ethylene added or clamp copolymers with higher ethylene content. The product name is a kind of high polymer
. The monomer is propylene. Polypropylene is obtained through addition polymerization reaction
. The chemical formula can be expressed as, and the structural simplified formula can be expressed as []
Advantages
Copolymer-type materials have lower heat distortion temperature (°C), low transparency, low gloss, and low rigidity, but have stronger impact strength. The strength increases with the increase of ethylene content. The Vicat softening temperature is ℃. Due to its high degree of crystallinity, this material has good surface stiffness and scratch resistance. There are no environmental stress cracking issues.
Features
Low density, heat-resistant, non-deformable, high stiffness, high surface strength, good chemical stability, excellent electrical properties, non-toxic, harmless, uniform color, smooth surface, easy installation and maintenance, long service life, easy to process, strong welding and other characteristics.
Application
Spray carrier for drinking water and sewage pipe seals, corrosion-resistant tanks and barrels, acid and alkali resistant industries, wastewater and gas emission equipment, scrubbing towers, clean rooms, equipment and machinery for semiconductor factories and related industries, food machinery And chopping board electroplating process, etc.
