What is PVC?
Polyvinyl chloride is a polymer of vinyl chloride monomer (VCM) in the presence of an initiator such as a peroxide or an azo compound; or a polymerization mechanism under the action of light or heat. The vinyl chloride homopolymer and the vinyl chloride copolymer are collectively referred to as vinyl chloride resins.
PVC is a white powder with an amorphous structure, with a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77-90 ° C, and decomposition at about 170 ° C. The stability to light and heat is poor, above 100 ° C or over a long period of time. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalytic decomposition, causing discoloration, and physical and mechanical properties are also rapidly declining. In practical applications, stabilizers must be added to improve the stability to heat and light.
Industrial production of PVC molecular weight is generally in the range of 50,000 to 110,000, with greater polydispersity, molecular weight increases with the decrease of polymerization temperature; no fixed melting point, 80-85 ° C begins to soften, 130 ° C becomes viscoelastic state, 160 ~ 180 ° C began to transform into a viscous flow state; has good mechanical properties, tensile strength of about 60MPa, impact strength of 5 ~ 10kJ / m2; has excellent dielectric properties.

A.The difference in an application:
Polyethylene (PE) applications: plastic wrap, vest plastic bags, plastic food bags, buckets, kettles, etc.
Polyvinyl chloride (PVC) applications: plastic wrap, plastic shoes and leather products, film, cable, plastic bags.
B.Different characteristics:
Polyethylene (PE) has a waxy feel and is lighter in weight and has certain transparency compared to the same plastic.
Polyvinyl chloride (PVC) characteristics: hard plastic, commonly used in industrial fields.
C.Material performance difference:
Polyethylene referred to as PE. It is a polymer of ethylene and is non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, electrical insulation. It is suitable for packaging materials for food and medicine, making utensils, medical equipment, and insulating materials for the electronics industry.
Polyvinyl chloride, referred to as PVC. It is a polymer of vinyl chloride. Polyvinyl chloride (PVC) is a synthetic material with many advantages and is an ideal material for engineering plastics. Good chemical stability, acid, and alkali resistance. Resistant to moisture, aging and flame retardant.
