Uses:
1, blended with general-purpose plastics to blend modifiers, used as impact modifiers in PVC rigid products, the effect is obvious.
2, used in the rubber industry, can be used as a special synthetic rubber alone, or blended with styrene-butadiene, nitrile, chloroprene, natural rubber, and processed into various vulcanized and non-vulcanized rubber products.
3, can be used as a halogen flame retardant for flammable synthetic materials.
The main characteristics of various models of CPE are as follows:
135A has good tensile properties and weather resistance, aging resistance, high filling, high impact resistance, etc. It is widely used in PVC Shaped material s, pipe fittings, plastic sheets, wire and cable protection. Set, injection hollow containers, automotive and communication equipment accessories. Also used in waterproof coils and rubber products.
130B has high strength, good toughness, excellent electrical properties and cold resistance, and has high filling properties for ferrite magnetic powder. It is widely used as a sealing strip for refrigerators, magnetic components for electromechanical products, and wire and cable sheathing.
135B has good tensile properties, good toughness, oil resistance and flame retardancy. Widely used in wire and cable sheathing, flame retardant conveyor belts, hoses, etc.
140B has good tensile properties, good tear resistance, excellent flame retardancy and good oil resistance. Used for flame retardant cables, conveyor belts, hoses, etc.
 Packing and storage:
Polypropylene woven bags lined with plastic bag.
Stored in a ventilated and dry warehouse, keep away from humidity and rain.
