, and may transition to a loose balance, the price will fall. But if this year's production of high-pressure rubber hose is not ideal, then the tension and balance will transition to a state of short supply, and the price may rise again. Therefore, this year's high-pressure rubber tube price trend is very large. There are many suppliers, purchasers and manufacturers. The steel wire woven high-pressure rubber tube structure is composed of liquid resistant synthetic rubber inner layer, steel wire reinforcement layer and weather resistant synthetic rubber outer layer. Application: mainly used for aircraft fuel oil, mine hydraulic support, oil field exploitation, engineering machinery for China market.

3.High impact polystyrene (HIPS) can be injection molded or extruded into various products, suitable for the shell of household electrical appliances, electrical appliances, instrument accessories, refrigerator lining, plate, television, recorder, telephone shell, stationery and educational supplies, toys, packaging containers, daily necessities, furniture, tableware, tray, tableware, structural foam products, etc.

Polystyrene has good fluidity, processability, easy coloring and good dimensional stability. It can be processed into various parts by injection molding, extrusion, blow molding, foaming, thermoforming, bonding, coating, welding, machining, printing, etc. It is specially suitable for injection molding. The materials can be directly applied without drying during injection molding. However, in order to improve the quality of the product, it can be pre dried for {{0}} h in a blast oven at 55 degree ~ 70 degree . The detailed processing conditions are as follows: the barrel temperature is about 200 degree , the mold temperature is 60-80 degree , the injection temperature is 170-220 degree , and the injection pressure ratio is 1.6-4.0. After forming, the products shall be treated at 70 degree for 2-4h in infrared lamp or blast oven.
