Low density polyethylene (LDPE)
Description:
Polyethylene is obtained by polymerization of ethylene a thermoplastic resin. Polyethylene is odorless, tasteless, non-toxic flammable white powder; Molded PE resins are processed by extrusion granulation waxy pellets, milky white appearance. Has excellent low temperature performance, chemical stability, resistance to most acid-base erosion. Room temperature, soluble in common solvents, water absorption, excellent electrical insulation properties.
LDPE description:
Low density polyethylene (LDPE) is the radical polymerization of ethylene under high pressure to obtain thermoplastic. LDPE having transparency, chemical inertness, good sealing ability, good performance of easy molding.
Features:
It's for film grade.
Non-toxic, odorless, matte cylindrical granules with good elongation resistance, electrical insulation. It has excellent workability and impact strength, good transparency and heat sealability.
Application:
LDPE can be used alone or blended with other members of the polyethylene family use. Widely used in packaging. Construction, agricultural, industrial and consumer markets.
It is used with the softer areas of lightweight packaging film, processed fruit nets and plastic products.
