● Heat (cold) resistance: HDPE pipes can be used safely when the temperature is between -80℃ and 100℃.
● External force resistance: HDPE pipe has excellent compression resistance at working temperature.
● Wear resistance: HDPE pipe has high wear resistance, and its thick wall can provide additional protection.
● Chemical resistance: HDPE molecular structure (alkane structure) is stable, and the pipeline has strong chemical resistance.
● Robustness: The welding strength of HDPE pipe is higher than that of the pipe itself, whether it is electric welding connection or hot welding connection.
● Dewing: HDPE pipe is a weak heat conductor, and it will not be dewed in a short cooling process.
● Fire performance: HDPE pipeline is not easy to burn at high temperature, and it will not release toxic gas when it burns in fire.
● Solar radiation: By adding carbon black, HDPE pipes can resist the aging and embrittlement of pipes caused by solar ultraviolet rays. In addition, according to our company's many years of construction experience, we can take measures such as painting on the outer wall of the pipeline and wrapping thin plates to solve the matching problem between HDPE pipe and building effect.
● Noise: HDPE pipe is a soft material, and its E elastic modulus is very small. Pipes can limit the sound propagation carried by air or solid.
● Thermal expansion coefficient: The thermal expansion and cold contraction of HDPE pipes are more obvious than other pipes, so the possible thermal expansion and cold contraction must be considered in the installation design. Although its expansion coefficient is large, its expansion stress is still very low because its elastic coefficient is much lower than other materials.

Specific gravity: 1.38g/cm3 molding shrinkage: 0.6- 1.5% Molding temperature: 160- 190℃.
The material has excellent mechanical and electrical properties, strong acid and alkali resistance, good chemical stability, but low softening point. Suitable for manufacturing thin plates, wire and cable insulation layers, seals, etc.
"The formability is 1. Amorphous substances have low hygroscopicity and poor fluidity. In order to improve fluidity and prevent bubbles, plastics can be dried in advance. The gating system of the mold should be thick and short, the gate section should be large, and there should be no dead angle. The mold should be cooled and the surface should be chrome plated. "
2. Very easy to decompose, it is easier to decompose when it contacts steel and copper at 200 degrees, and corrosive and irritating gases escape during decomposition. The molding temperature range is small.
3. When using the nozzle of the screw injection machine, the aperture should be large to prevent the dead angle from being stuck. If there is an insert, it should be preheated. "
