● Resistance to heat (cold): temperature between -80 ℃ to 100 ℃, HDPE pipe can be used safely.
● Resistance to external forces: under the working temperature conditions, HDPE pipes have excellent compression resistance.
● Resistance to abrasion: HDPE pipe is highly resistant to abrasion and its thick wall provides additional protection.
● Chemical resistance: HDPE molecular structure (chain alkane structure) is stable, the pipe is highly resistant to chemicals.
● Firmness: Whether HDPE pipe is connected by electrofusion welding or heat fusion welding, the strength of the weld is higher than the strength of the pipe itself.
● Condensation: HDPE pipe is a weak heat conductor, a short cooling process, the pipe will not produce condensation.
● Performance in the fire: at high temperatures, HDPE pipe is not easy to burn, pipe burning in the fire will not release toxic gases.
● Solar radiation: by adding carbon black, HDPE pipe can resist the aging and embrittlement of pipe caused by solar ultraviolet rays. In addition, according to our company's many years of construction experience, we can take measures to solve the problem of matching the HDPE pipe with the architectural effect, such as painting and wrapping the outer wall of the pipe with a thin plate.
● Noise: HDPE pipe is a soft material, E modulus of elasticity is very small, the pipe can limit the air or solid as a carrier of sound propagation.
● Thermal expansion coefficient: HDPE pipe's thermal expansion and contraction is more obvious than other pipe materials, in the installation design must consider the possible thermal expansion and contraction. Despite its large coefficient of expansion, the expansion stress is still low because the coefficient of elasticity is much lower than other materials.

Specific Gravity:1.38g/cm3. Molding shrinkage:0.6-1.5% Molding temperature:160-190℃
Material Properties Mechanical properties, electrical properties are excellent, acid and alkali resistance is very strong, chemical stability is good, but the softening point is low. Suitable for making sheet, wire and cable insulation, seals and so on.
"Molding properties 1. Amorphous material, moisture absorption, poor fluidity. In order to improve the fluidity, to prevent the occurrence of air bubbles, the plastic can be pre-dried. The mold casting system should be thick and short, the gate cross-section should be large, there should be no dead ends. The mold should be cooled and the surface should be chrome plated.
2. Very easy to decompose, at a temperature of 200 degrees and steel. It is easier to decompose when it comes in contact with steel and copper at 200 degrees Celsius, and corrosive and irritating gases will escape when it decomposes. Irritating gases are emitted during decomposition. Small molding temperature range.
3. Screw injection machine nozzle, the aperture should be large, in order to prevent dead-end stagnant material. Good not to bring the inserts, if there are inserts should be preheated."
