PE materials:
Polyethylene (POLYETHYLENE, PE) is a polymer formed by the polymerization of ethylene, the product development has been about 60 years of history
, Five generic first resin production in the global polyethylene.
Polyethylene according to the polymerization method, low molecular weight, different chain structures, from high density polyethylene, linear low density polyethylene, and
Low density polyethylene.
Low-density polyethylene (LOW DENSITY POLYETHYLENE, LDPE), commonly known as high pressure polyethylene, due to the lower density material most
Soft, mainly used in plastic bags, agricultural film.
High-density polyethylene (HIGH DENSITY POLYETHYLENE, HDPE), commonly known as the low-pressure polyethylene, compared with LDPE and LLDPE
There's a higher temperature, oil resistance, vapor permeability and resistance to environmental stress cracking resistance, in addition to electrical insulation and impact resistance
And cold can be very good, mainly used in blow molding, injection molding and other fields.
Linear low density polyethylene (LINEAR LOW DENSITY POLYETHYLENE, LLDPE), with a small amount of ethylene is advanced Α-
An olefin polymerization catalyst in the presence of the copolymer. LLDPE and LDPE appearance similar to some poor transparency, but the surface light
Ze good low temperature toughness, high modulus, flexural resistance and stress cracking resistance, impact strength at low temperatures preferred advantages.
LLDPE applications have penetrated almost all the LDPE market. LLDPE and HDPE stage in the growth stage of the life cycle
; LDPE in 1980 on behalf of the late maturing gradually into the development of the world's rare LDPE equipment has been put into operation. Extruded polyethylene available
, Injection molding, blow molding and melt-spinning methods, widely used in industry, agriculture, packaging and daily industry, in
China is widely applied, the film is its biggest user, consuming about 77% of low density polyethylene, high density polyethylene 18%
In addition, plastic products, wire and cable, hollow products and so account for a large proportion of their consumption structure, the plastic work
Occupies a pivotal position in the industry
