Polyvinyl chloride (PVC) is the biggest characteristic of flame retardant, so is widely used in fire protection applications.But the polyvinyl chloride (PVC) in the process of combustion will release hydrogen chloride and other toxic gases, such as dioxin.
&©|160;
Polyvinyl chloride (PVC) combustion can be divided into two steps.In 240 oC to 340 oC before burning decomposition of hydrogen chloride gas and alkadiene contain a double bond, and then in 400-470 oC carbon burning.

PVC formability:
&©|160;
1. Amorphous materials, hygroscopicity, liquidity is poor, in order to improve the liquidity, prevent bubbles and appropriate drying in advance.
&©|160;
2. Easy to decompose, especially at high temperature in contact with the steel and copper are more likely to break down decomposition temperature (200 degrees c).Molding temperature range is small, must be strictly controlled temperature for the material.
&©|160;
3. Use of screw injection machine and direct the nozzle aperture should be larger, in case of blind Angle hysteresis material.
&©|160;
4. Mould gating system should be thick, the appropriate gate section, mould should be cooling, mould temperature 30 to 60 de |
