PVC resin is a polymer compound formed by polymerization of vinyl chloride monomer (VCM), and its structure unit is [CH2-CHCL]n. polymerization degree is usually 590-1500. According to the content of residual polyethylene monomer in PVC resin can be divided into: industrial grade, food hygiene grade and medical grade. The appearance of PVC resin is white powder.
PVC resin SG3 SG5 SG8 is flame-retardant (flame retardant value above 40), high chemical resistance (resistant to concentrated hydrochloric acid, 90% sulfuric acid, 60% nitric acid and 20% sodium hydroxide), mechanical strength And the advantages of good electrical insulation. But its heat resistance is poor, with a softening point of 80�°C, it starts to decompose and change color at 130�°C, and precipitate HCI.
Application: It is widely used in the production of polyvinyl chloride boardy leatheroid, paint and adhesive agents, paint and adhesive.
Packing: 25kgs two layers draft paper bag or 1000kgs PP bag.
Pet is an opalescent or light yellow highly crystalline polymer with smooth and glossy surface. It has good creep resistance, fatigue resistance, wear resistance and dimensional stability, small wear and high hardness. It has the largest toughness in thermoplastic plastics: good electrical insulation performance, little influence by temperature, but poor corona resistance. It is non-toxic, weather resistant, chemical resistant, stable, low water absorption, weak acid and organic solvent resistance, but not resistant to hot water immersion and alkali.
PET resin has high glass transition temperature, slow crystallization rate, long molding cycle, large molding shrinkage, poor dimensional stability, brittle molding and low heat resistance.
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. Itis stable to most chemical except strong oxidizers. Inorganic acid, alkali and salt solutions have almost no damaging effect on PP.
PP has good heat resistance and low density. Its melting point is at around 165â??. It has high tensile strength and surface hardness and good environmental stress crack resistance.It can withstand 120â?? continuously.
Sinopec is the largest PP producer in China,Its PP capacity accounted for 45% of the country's total capacity. The company currently has 29 PP plants by the continuous process (including those under construction)

PET Chip for Spunbond Non-Woven Fabric
Semi-dull Grade Specialty Polymer for Nonwovens
Product Description:
Our non-woven fabric polyester chip is a high-viscosity PET material designed specifically for the production of spunbond nonwoven fabrics. Unlike traditional textile production processes, nonwovens are created directly from fiber or polymer without the need for yarn spinning. PET chips are an essential raw material in this process.
