PVC is polyvinyl chloride (English: Polyvinyl Chloride, abbreviated as: PVC), which is a polymer material obtained by addition polymerization of vinyl chloride. It is the third most widely produced sy

The natural color is light yellow, translucent and shiny. The transparency is better than that of polyethylene and polypropylene, but worse than that of polystyrene. Depending on the dosage of additiv

From the perspective of consumption structure, 65% of PVC products are currently consumed in hard products (including 15% of pipes, 5% of pipe fittings, 30% of doors and windows and profiles, 8% of ha

PVC is a polyvinyl chloride plastic with bright color, corrosion resistance, firmness and durability. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents i

Calcium carbide method: use calcium carbide (calcium carbide CaC2) to generate acetylene (C2H2) in contact with water, synthesize acetylene and hydrogen chloride (HCl) to produce vinyl chloride monome

Pressure resistance is an important parameter of bellows performance. The maximum static pressure that the bellows can withstand without plastic deformation on the waveform at room temperature is the

The maximum displacement that can be obtained without plastic deformation of the bellows is called the allowable displacement of the bellows.

The role of PVC lubricants is to improve the fluidity of resins and the release properties of products in plastic processing, and prevent defects due to adhesion in the machine or mold.

The development of PVC stabilizers has brought a lot of convenience to our lives. The research and development of each additive will lead to PVC products that affect our lives. The PVC material is pol

PVC heat stabilizers are mainly used for PVC and other chlorine-containing polymers. It has been found that PVC plastic can only be processed at a temperature above 160 °C, and it begins to thermally

The role of PVC lubricants is to improve the fluidity of resins and the release properties of products in plastic processing, and prevent defects due to adhesion in the machine or mold.

ABS resin is currently the largest and most widely used polymer. It organically unifies the various properties of PS, SAN and BS, and has excellent mechanical properties with balanced toughness, hardn
