Product details

山东群英会怎么玩Polyethylene external protecting tube with high density polyethylene materials, has high mechanical strength and good corrosion resistance, can protect the pipes in the process of transportation, installation and use to avoid the damage caused by external factors. The outer casing should be added anti-oxygen agent, uv stabilizer and carbon black.

High-density polyethylene products have high abrasion resistance, impact resistance, excellent resistance to internal pressure strength, environmental stress cracking resistance, good self-lubricating, anti adhesion, unique low temperature resistance, good chemical stability and superior performance, are widely used in metallurgy, electric power, petroleum, textile, papermaking, etc.

Characteristics of the outer sheath of polyethylene:

1. Excellent wear resistant housing plastic crown, 4 times higher than nylon 66 and polytetrafluoroethylene, 6 times higher than carbon steel.

2. The friction coefficient is small, not adhesive, and the self-lubricating property is similar to ptfe, and the friction coefficient is only 0.07-0.11.

3, of plastic, the impact strength of PC 2 times, ABC's five times, and can keep under liquid nitrogen temperature (196 ℃) and high toughness, especially excellent low-temperature impact resistance, impact energy absorption value of all the plastic for high value, sound attenuation effect is good。

5. Excellent anti-aging properties. Under natural sunshine conditions, the aging life of high-density polyethylene is 50 years. As a new type of engineering plastic, a variety of excellent performance.

6。 High chemical stability, capable of resisting all kinds of corrosive medium and organic medium in a certain temperature and concentration range。
