High-density polyethylene color plates machinery dedicated color plates of high density polyethylene polymer polyethylene color plate color plates UPE polyethylene color plates hdpeE polyethylene color plates Texas SHENGTONG After years of production experience and a bold attempt to put a lot of time and effort Finally in 2012 successfully developed, the two three different colors of the perfect combination of high molecular weight polyethylene plate, remains perfect properties of polymer polyethylene plate, such as a high abrasion resistance, UV, impact resistance, low friction coefficient, good self-lubricating properties, excellent resistance to temperature, chemical resistant, nonstick, itself non-corrosive, non-toxic, tasteless and odorless. High-density polyethylene - the material properties of the basic characteristics of [] High density polyethylene is an opaque white wax-like material, the proportion is lighter than water, accounting for 0.941 ~ 0.960, soft and resilient, but slightly harder than LDPE, also slightly stretchy non-toxic, tasteless. Combustion characteristics [] flammable, away from the fire will continue to burn, flame yellow top, blue bottom, it will melt when burned, liquid dripping, no smoke coming out, at the same time, the odor emitted when burning paraffin. The main advantages] acid, 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, close to PP, PP than tough, but not as good as the surface finish PP. The main drawback of] poor mechanical properties, poor ventilation, easily deformed, easy to aging, prone to brittle, brittle lower than PP, easy to stress cracking, low surface hardness, easy to scratch. Difficulty printing, printing, the need for surface discharge treatment, not plated, matte. [Applications] for extrusion packaging film, ropes, bags, fishing nets, water pipes; injection of low-grade commodities and housing, non-load-bearing components, plastic box, turnover box; extrusion blow molded containers, hollow products, bottles. [] HDPE injection molding process has numerous applications, ranging from thin reusable cups to 5-gsl beverage cans, domestic production of HDPE consumption 1/5. Injection molding grade melt index generally 5 to 10, having a lower mobility grade toughness and has high mobility workability grade. Uses include thin-walled packaging and food commodities; toughness, durable food and paint cans; high resistance to environmental stress cracking applications, such as small engine fuel tank and 90-gal trash cans. Usually the melting point of HDPE 142 ℃, decomposition temperature was 300 ℃; large injection temperature adjustable range. When the injection, the general temperature of 180 ℃ --230 ℃; when the olefin plastic because it does not absorb water, production, without drying, but for the quality of products, are available at 60 ℃ drying 1hr, to discharge floating; poly The melt viscosity of ethylene large flow longer than the small, thin-walled products may be out of plastic, and therefore, a relatively large gate and runner; products easy with static electricity, the surface is easy to absorb and Egypt. Shrinkage rate of 16 ‰; overflow edge is 0.05mm.
