Extruded

A process in which the material is thermoplasticized while being pushed forward by the screw through the action of the extruder barrel and the screw, and is continuously made into various cross section products or semi-finished products through the machine head.
polypropylene
Polypropylene (PP) Is a polymer formed by the addition reaction of propylene.White waxy material, transparent and light in appearance.The chemical formula is (C3H6) N, the density is 0.89 ~ 0.91g/cm3 inflammable, the melting point is 165℃, and the temperature ranges from -30 ~ 140℃ to soften around 155℃.The polypropylene of Longchang petrochemical can resist the corrosion of acid, alkali, salt liquid and a variety of organic solvents under 80℃, and can be decomposed under high temperature and oxidation.Polypropylene is widely used in clothing, blankets and other fiber products, medical equipment, cars, bicycles, spare parts, transportation pipelines, chemical containers and other production, also used in food, medicine packaging.

High density polyethylene
High density polyethylene (HDPE) is a white powder or granular product.Non-toxic, tasteless, crystallinity is 80% ~ 90%, softening point is 125 ~ 135℃, using temperature up to 100℃;Hardness, tensile strength and creep property are better than low density polyethylene.Longchang petrochemical high density polyethylene has good wear resistance, electrical insulation, toughness and cold resistance.Good chemical stability, at room temperature, insoluble in any organic solvents, acid, alkali and various salts corrosion resistance;The film has low permeability to water vapor and air and low water absorption;Aging resistance, environmental stress cracking resistance is not as good as low density polyethylene, especially thermal oxidation will make its performance decline, so the resin must be added antioxidant and uv absorbent to improve the shortage of this aspect.The thermal deformation temperature of hdPE film is low under the condition of stress, so attention should be paid in application.

Linear low density polyethylene
Linear low density polyethylene (LLDPE) is a non-toxic, tasteless and odorless milky white particle with a density of 0.918~0.935g/cm3.It compared with LDPE, longchang petrochemical linear low density polyethylene with high softening temperature and melting temperature, has good strength and toughness, rigidity, heat resistance, cold resistance is good wait for an advantage, but also has good environmental stress cracking resistance, resistance to impact strength, tear strength and other properties, and acid, alkali, organic solvent and widely used in industry, agriculture, medicine, health and daily life supplies, and other fields.
