HDPE injection molding grade has good balance of rigidity and toughness, good impact resistance and excellent of
low temperatures resistance and good environmental stress crack
resistanse. The resin has good rigidity and abrasion resistance, and good processability.
Thermoplastic resin extrusion or injection molding of the tubular plastic billet, while hot (or heated to soften the state), placed in the split mold, closed immediately after the billet into the compressed air, the plastic billet blowing and close to the inner wall of the mold, ...
HDPE is synthesized under low pressure and is therefore also called low-pressure polyethylene. HDPE is mainly a linear molecular structure and has little branching. It has a high degree of crystallization and high density. It can withstand high temperatures and has good rigid...
PP contains no polar groups and has excellent electrical insulation properties. Its water absorption rate is less than 0.01%. PP is a semi-crystalline polymer with good chemical stability. It is stable to most chemical except strong oxidizers. Inorganic acid, alkali and salt solu...
Sinopec PP homopolymer has higher crystallinity, high rigidity, high tensile strength, high modulus and good thermal distortion resistance. Products made from this resin are characterized by short processing time, good scratching resistance and fluidity.
Polystyrene (PS) , is a synthetic resin made byhomopolymerization of styrene monomers or with other comonomers. In the molecular structure of homopolymer, the main chain is a saturated carbon chain with benzene rings as the lateral group. The resin is a non-crystalline linear pol...
General-purpose polystyrene is a thermoplastic resin, colorless, odorless, tasteless and shiny, transparent beads or granular solid. Density 1.04 ~ 1.09, transparency 88% ~ 92%, refractive index 1.59 ~ 1.60. The melting temperature of the product is 150 ~ 180℃, the thermal decomp...
