Why Is The Bag Made Of Pvc Durable?

PVC material is a kind of plastic decorative material, which is short for polyvinyl chloride material, PVC (Polyvinyl Chloride, short for PVC) resin is a thermoplastic polymerization from vinyl chloride monomer (Vinyl Chloride Monomer, short for VCM). It is made of PVC resin as the main raw material, with the appropriate amount of anti-aging agent, modifier, etc., through mixing, calendering, vacuum forming and other processes. PVC is an amorphous polymer, containing 5%-10% crystallinity microcrystals (melting point 175 degrees), the molecular weight, crystallinity, softening point and other physical properties of PVC vary with the polymerization reaction conditions (temperature).

Because of the hazards it poses to the human body, Europe, Japan and South Korea have to limit the products that use PVC as raw material. In general, the outstanding advantages of PVC resin plastic products are flame retardant, abrasion resistant, chemically resistant, and low leakage of gas and water vapor.

In addition, it is a general-purpose material with the best price/performance ratio because of its comprehensive mechanical performance, transparent products, electrical insulation, heat insulation, sound insulation and shock absorption.

Because PVC is a hard plastic, to make it soft, it is necessary to add a large number of plasticizers, plasticizers are easily released in the heated environment.
