Influence of main indexes of chlorinated polyethylene (CPE) on modification of rigid PVC(2)… Effect of different volatile CPE on PVC modification:CPE manufacturers generally use aqueous phase (acid phase) suspension chlorination process, in the chlorination reaction process, some hydrogen atoms in polyethylene molecules are replaced by chlorine atoms, resulting in chlorinated polyethylene and hydrogen chloride. Since the production of CPE is carried out in suspension an…

AP766 flame retardant ProFlame® PNPO-766 (AP766) PNPO-766 is a kind of Halogen-Free flame retardant , which develops its effectiveness through phosphorus/nitrogen synergism.When the polyolefine on exposure to flame, the carbon foam layer formed protects the polymer through its heat insulating effect to reduce further oxygen access and prevent dripping of the polymer. At the sam…

Influence of main indexes of chlorinated polyethylene (CPE) on modification of rigid PVC (1… Polyvinyl chloride (PVC) is widely used in chemical industry, building materials and other fields because of its advantages of high strength, flame resistance and chemical corrosion resistance, and is the second largest general plastic in the world today. However, the toughness of PVC is low, so that its application is limited, so it must be toughened and modified. The commonly …

How Does a Twin-Screw Extruder Work? -1 The twin screw extruder has traditionally been used to produce pellets so that the material can be continuously fed into secondary processing equipment, such as injection molding machines or single-screw extruders. In addition, twin-screw extruders can also produce films, fibers, sheets pipes, profiles..., which is called direct extrusion. The two forms of products are obtained …
