PE plastic namely polyethylene plastic, corrosion resistance, electrical insulation (especially high-frequency insulation), suitable for the production of low-pressure polyethylene corrosion-resistant parts and insulating parts; suitable for production of high-pressure polyethylene films; UHMWPE suitable for production of shock absorption, abrasion resistance and transmission parts. There are three main types of commonly used PE: LDPE material commonly known as flowers or tube feeding, generic low-density polyethylene, high-pressure polyethylene, the English name of low density polyethylene. LDPE is a translucent white wax-like material, the proportion is lighter than water, soft and ductile, slightly stretchy, non-toxic, tasteless, acid and alkali resistance to organic solvents, excellent electrical insulation, low temperature, can still maintain a certain toughness. Commonly used in packaging film extrusion, is complex films, hoses, low-grade commodities and housing, extrusion blow molded containers. Commonly known as rigid HDPE soft, generic high-density polyethylene, low-pressure polyethylene high density polyethylene HDPE English High Density Polyethylene character is an opaque white wax-like material, the proportion is lighter than water, soft and resilient, but slightly harder than LDPE also slightly stretchy, non-toxic, tasteless, acid resistance, organic solvents, excellent electrical insulation, low temperature, can still maintain a certain toughness. Surface hardness, tensile strength, mechanical strength such as rigidity higher than LDPE, close to PP, PP than tough, but not as good as the surface finish PP. HDPE high density polyethylene used in packaging film extrusion, ropes, bags, fishing nets, water pipes. Low-grade injection molded plastic products and housing, non-load-bearing components, plastic box, turnover box. Extrusion blow molded containers, hollow products, bottles. LLDPE LLDPE generic, low density polyethylene, LLDPE linear high density polyethylene character is an opaque white wax-like material, the proportion is lighter than water, soft and resilient, but slightly harder than LDPE, also slightly stretchy, non-toxic, tasteless, acid and alkali resistance to organic solvents, excellent electrical insulation, low temperature, can still maintain a certain toughness. Surface hardness, tensile strength, mechanical strength such as rigidity higher than LDPE, but lower than HDPE; LLDPE puncture resistance is the best tear resistance, particularly suitable for the production of film, to produce films thinner than LDPE, but the strength high. For extrusion packaging film, tape, cable; to produce the film, also called the proposed paper film. Commodity and housing for low-grade injection. For extrusion blow molded containers, hollow products, bottles. LDPE HDPE LLDPE three kinds of polyvinyl monomers are the same, but, in the synthesis of the polyethylene, the process conditions employed are not the same, therefore, it generates three different polyethylene varieties. Difference LDPE HDPE LLDPE three materials: LDPE and HDPE difference is mainly the difference in density, thereby causing difference in mechanical properties on a rigid, one pliable; LLDPE and their differences, mainly in the molecular structure, LLDPE has more branched chain, and therefore, this material is that is flexible and rigid.
