Injection molding

The thermoplastic or thermosetting materials using plastic molding mold into various shapes of plastic products of the main molding equipment, injection molding is through the injection molding machine and mold to achieve.
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.

Acrylonitrile-Butadiene-Styrene
Styrene - butadiene - styrene block copolymer (SBS) is the largest yield of SBCs (accounting for more than 70%), the lowest cost, a widely used variety, is based on styrene, butadiene as monomer triblock copolymer, both plastic and rubber characteristics, known as the "third generation of synthetic rubber.Similar to styrene butadiene rubber, SBS can contact with water, weak acid, alkali and so on, with excellent tensile strength, large surface friction coefficient, good low temperature performance, excellent electrical performance, good processing performance and other characteristics, become the largest consumption of thermoplastic elastomer.

Polystyrene (diphenyl)
Plastics that can be used as engineering materials and as substitutes for metal to make machine parts, etc.Longchang petrochemical engineering plastics have excellent comprehensive properties, such as high rigidity, creep, high mechanical strength, good heat resistance, good electrical insulation, and can be used in harsh chemical and physical environments for a long time. They can be used as engineering structural materials instead of metals, but the price is expensive and the output is small.

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.

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.
