Anti-ultraviolet ABS-mixing ABS resin with PVC to produce alloy materials can achieve superior flame retardant properties. We know that PVC plastic has the advantages of good rigidity, high strength, flame retardancy, corrosion resistance, good electrical insulation and adjustable hardness, but its processability is poor, notch impact strength and thermal deformation temperature are low, and it is fragile. ABS resin is the largest and most widely used polymer at present. It organically unifies various properties of PS, SAN and BS, and has excellent mechanical properties of toughness, hardness and rigidity in balance. This kind of PVC plastic is difficult to replace engineering plastics, which greatly limits its application. ABS resin has good comprehensive properties, high impact strength and surface strength in a wide temperature range, high thermal deformation temperature, good dimensional stability and certain chemical stability, but poor weather resistance and heat resistance, flammability and high price. The two have good compatibility. The properties of PVC/ABS alloy complement each other. It not only has the advantages of impact resistance, low temperature resistance and easy molding of ABS resin, but also has excellent flame retardancy and corrosion resistance of PVC. ABS/PVC alloy improves the flame retardancy of ABS and has been widely used in building materials, automobile industry, electronic and electrical industry and medical devices. In addition, ABS/PC alloy combines the advantages of ABS and PC, and has high impact strength, flexibility, rigidity and heat resistance. Used in mechanical parts, electrical appliances and telecommunication equipment. PC plastics are heat resistant, flame retardant, high impact resistance, medium gloss, good impact resistance, good processability, good color stability, good weather resistance, medium heat resistance, good self-extinguishing property and good flame retardancy.
