Q
PVC is a kind of what material? For example, what is this bag made of?
A

PVC material is a kind of plastic decoration material is polyvinyl chloride, referred to as PVC (Polyvinyl Chloride, referred to as PVC) resin is made of vinyl chloride monomer (Vinyl Chloride Monomer, referred to as VCM) polymerization of thermoplasticpolymers. Are made of PVC resin as the main raw material, adding anti-aging agent, modifier, through mixing, calendering, vacuumtechnology and become. The genus PVC amorphous polymers, micro crystal containing the crystallinity of 5%--10% (melting point of 175 degrees). The molecular weight, the crystallinity of PVC, softening point and other physical energy with polymerization conditions (temperature) and variable. With PVC resin as binder, and stabilizer, plasticizer, filler, pigment and modifying agents and other auxiliaries mixed plasticizing, processing into PVC resin plastic. PVC material has the advantages of light weight, heat insulation, thermal insulation, waterproof, flame retardant, convenient construction etc.. Specifications, colors,patterns are highly decorative, is widely used in production and life. For example, PVC pipe, PVC plastic doors and windows, andPVC containing plastic toys, electric wire and cable. Because it is for the human body harm, Europe, Japan and South Korea and other countries have restrictions on using PVC as raw material and products. PVC resin plastic product advantages is generallydifficult to burn, abrasion resistance, chemical corrosion resistance, low leakage gas water well. In addition, the comprehensive mechanical, transparency, electrical insulation, heat insulation, noise, vibration or to price ratio is the most common type of material with excellent. Defect is the thermal stability and anti impact is poor, both easy to produce is hard or soft in the process of using PVC crisp. General PVC contains not be relevant national standard allows the use of two (2 - ethylhexyl) adipate (DEHA) plasticizers, DEHA in the high temperature (100 degrees Celsius) easily released, contact the body is harmful to health. Because PVC is a hard plastic, making it softer, must add a plasticizer, plasticizer easily in the heatingenvironment released. If you are using DEHA, it would interfere with the body endocrine, cause women to breast cancer, birth defects, reduce the number of male sperm, or even mental diseases.
