1, synthetic materials with different properties
Polyethylene ethylene polymer, non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, good electrical insulation. It is suitable for food and drug packaging materials, the production of eating utensils, medical equipment, but also for the electronics industry, such as insulation materials.
Polyvinyl chloride is a polymer of vinyl chloride. Amorphous structure of white powder, small degree of branching, relative density of about 1.4, glass transition temperature of 77 ~ 90 ℃, about 170 ℃ began to decompose.
2, different characteristics
Polyethylene (PE) feel waxy, compared with the equivalent plastic quality is relatively light, there is a certain degree of transparency.
Polyvinyl chloride (PVC) characteristics: hard plastic, commonly used in industrial areas.
3, the application of different
Polyethylene (PE) applications: plastic wrap, undershirt plastic bags, plastic food bags, buckets, jugs and so on.
Polyvinyl chloride (PVC) applications: cling film, plastic shoes and leather products, film, cable, plastic bags.
Expanded Information
