High density Polyethylene (HDPE): is a highly crystalline non-polar thermoplastic resin produced through the copolymerization of ethylene and a small amount of α-olefin monomer. HDPE is synthesized under low pressure and is therefore also called low-pressure polyethylene. HDPE is mainly a linear molecular structure and has little branching. It has a high degree of crystallization and high density. It can withstand high temperatures and has good rigidity and mechanical strength and anti-chemical corrosion. This hdpe recycyled material proves clean and free of impurities, it can be directly processed and produced, with characteristics of easy extrusion, good impact resistance, excellent low temperature resistance and can be applied to municipal pipes, water supply pipes, jacking pipes, carat pipes, inner rib pipes, steel belt winding pipes, corrugated pipes, pipe fittings, wood plastic, blowing pipes, blow molding (cardboard, bottle barrel), blow film and other products. it is hdpe extrusion grade for making the gas pipe especially, water pipe as well, match the pe100 pipe grade pipe. 

Low-density polyethylene (LDPE) is a synthetic resin using a high pressure process via free radical polymerization of ethylene and is therefore also called "high-pressure polyethylene". Since its molecular chain has many long and short branches, LDPE is less crystalline than high-density polyethylene (HDPE) and its density is lower. It features light, flexible, good freezing resistance and impact resistance. LDPE is chemically stable. It has good resistance to acids (except strongly oxidizing acids), alkali, salt, excellent electrical insulation properties. Its vapor penetration rate is low. LDPE has high fluidity and good processability. It is suitable for being used in all types of thermoplastic processing processes, such as injection molding, extrusion molding, blow molding, rotomolding, coating, foaming, thermoforming, hot-jet welding and thermal welding.

• High percentage elongation at break

• Usable at temp. of -50°C to + 85°C

• No water absorption

1.Film grade is widely used in the production of packing bag, film and so on.
2.Blow molding grade for making various bottles, cans, tanks , barrels 3.Injection-molding grade is for making food cases, plastic  trays, goods containers.
4.Blow film product:Foodstuff packing bag,groceries shopping bags, chemical fertilizer  lined with film, etc
5.Extruded product: Pipe,tube mainly used in gas transportation, public water and chemicals  transport, such as building materials, gas pipe, hot water drain pipe etc: sheet material is  mainly used in the seat, suitcase, handling containers.

Shanghang Xinchanglong Industrial Co., Ltd has been engaged in the R&D and Production and Sales of plastic impact modifiers for more than 10 years. Our products are very mature in the market, including plastic impact modifiers (toughening agents), melting index agents, deodorizers, brightening agents, compatibility agents, etc., which can improve the performance of new or recycled plastics in various aspects, including improving product toughness, gloss, UV resistance, low temperature brittleness, fracture growth rate, melting index, so the products can yield the best results in injection molding, extrusion, blow molding, pelletizing, etc. Many customers apply the products in the production of outdoor garbage cans, pipes, electrical appliance housings, buckets, Auto parts, motorcycle shells, lead battery shells and plastic films. In addition, the company has chemical auxiliaries, oil fillers, wire harness fillers, glass yarn, etc. Besides these existing standard products, Shanghang Xinchanglong Industrial Co., Ltd also supports customized formulations for your special modification needs.
