Used for plastic injection products, food packaging materials, medical equipment, drugs, hollow blow molding products, fiber, etc.
LLDPE product non-toxic, tasteless, odourless, white particles. Compared with LDPE with high strength, good toughness, strong rigidity, heat resistance, cold-resistant etc, and also has a good environmental stress cracking resistance, resistance to tear strength and other properties, and acid, alkali, organic solvents, etc.Low density polyethylene (LDPE) is a kind of plastic material, it is suitable for thermoplastic processing a variety of molding process, molding, good workability. LDPE main purpose is for thin film product, also used in plastic injection products, medical devices, pharmaceutical and food packaging materials, hollow blow molding products, etc.Pure polyethylene excluding polarity gene, so has good dielectric properties. Molecular weight on the dielectric properties of polyethylene doesn\'t happen, but if in the polyethylene contains impurities, such as catalysts, metal exist in the ash and molecular polar groups (such as hydroxyl and carbonyl group), with its dielectric properties such as dielectric constant and dielectric loss.LLDPE and HDPE is belong to the same linear polyethylene, but LLDPE is ethylene and alpha olefin copolymerization. Because of the LLDPE more than the high density of copolymerization monomer copolymer, thus linear main chain of LLDPE, there are a lot of short branched chain, leading to the degree of crystallinity and low density polyethylene.In melt stretch, LLDPE under various strain rate usually has lower viscosity. This means it will not be like LDPE in generated when the tensile strain hardening. With increasing the deformation rate of polyethylene. LDPE shows a staggering increase of viscosity, this is a low density polyethylene molecular chain.According to the type of polymerization monomer, LLDPE is mainly divided into three kinds of copolymer: C4 (butylene - 1), C6 (hexene - 1), and C8 (octene - 1). Among them, is the world\'s largest LLDPE resin production, butene copolymer and hexylene copolymer is currently the fastest growing varieties of LLDPE. In LLDPE resin, typical of copolymerization monomer dosage is 5% ~ *0% weight fraction, average usage is about 7%. Metallocene based LLDPE plastic body (mLLDPE) with traditional LLDPE 3 times more than average comonomer content.

General single lip wind ring stable enough to use on LDPE. LLDPE characteristic of membrane bubble demand more perfect lips wind ring to stability. Using internal film cooling on the lips, the wind bubble can increase membrane bubble stability, at the same time improve the film production capacity under high productivity. In addition to membrane bubble better cooling, a lot of film factory and LDPE blend method used to enhance LLDPE to dissolve the word, the LLDPE extrusion can be done on the existing LDPE film equipment, when the concentration of the blend of LDPE LLDPE was *0%. Processing **0% LLDPE or rich in LLDPE and LDPE blend material, using general of LDPE extrusion molding machine, equipment necessary improvement
