What are the main specifications and sizes of PVC pipe fittings?

Answer:

PVC material is a kind of plastic decoration materials, PVC material is referred to as PVC (Polyvinyl Chloride, referred to as PVC) resin is a vinyl chloride monomer (Vinyl Chloride Monomer, referred to as VCM) polymerized thermoplastic polymers. Are made of PVC resin as the main raw material, adding anti-aging agent, modifier, through mixing, calendering, vacuum technology and. PVC is an amorphous polymer, crystal containing the crystallinity 5%--10% (melting point of 175 degrees).

PVC material has light, heat insulation, heat preservation, moisture-proof, flame retardant, simple construction and so on. Specifications, colors, patterns, and very rich decoration, is widely used in production and life. For example, PVC water pipes, PVC plastic doors and windows, and plastic toys containing PVC, wires and cables. Because of its harm to human body, Europe, Japan and South Korea and other countries have restrictions on using PVC as raw material and products. PVC resin has the advantages of plastic products is generally difficult to burn, abrasion resistance, chemical resistance, low leakage, good gas vapor. In addition, comprehensive mechanical energy, products transparent, electrical insulation, insulation, noise elimination, shock elimination, or better, is the most superior price than the general type of material. The defect is thermal stability and shock resistance is poor, whether it is hard or soft, PVC is easy to produce brittle during use. General PVC is not containing the relevant national standards allow the use of two (2 - ethylhexyl) adipate plasticizer (DEHA), DEHA in the high temperature (over 100 degrees Celsius) easily released, after contact with human health hazard.

Because PVC is a hard plastic, to make it soft, a large amount of plasticizers must be added. Plasticizers are easy to release in a heated environment. If you are using DEHA, it will interfere with the human endocrine, cause women to breast cancer, birth defects, reduce the number of male sperm, or even mental disorders.
