WATERPROOFING MEMBRANE MANUFACTURER
Basic knowledge of pre-applied HDPE membrane
The pre-applied HDPE membrane is a plastic coil composed of HDPE, which is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section.
Pre-applied HDPE membrane manufacturers tell you that PE has excellent resistance to most household and industrial chemicals. Certain types of chemicals are chemically aggressive, such as aggressive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride). The polymer is not hygroscopic and has good water vapor resistance.
HDPE has good anti-corrosion performance, electrical performance, moisture-proof performance, anti-leakage performance and high tensile strength, so it is very suitable for wire and cable, engineering anti-seepage, breeding anti-seepage, oil tank anti-seepage, basement anti-seepage, artificial Lake anti-seepage and other fields. The pre-applied HDPE membrane has excellent impact resistance, so this is true at room temperature and even at temperatures as low as -40F.
HDPE is a non-toxic, tasteless, odorless white particle of high molecular polymer, with a melting point of about 110℃-130℃ and a relative density of 0.918-0.965; it has good heat resistance and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, good resistance to environmental stress cracking and tear strength, pre-applied HDPE membrane manufacturers tell you that as the density increases, the mechanical properties and barrier properties will correspond Improve, heat resistance, and tensile strength are also higher; can resist acid, alkali, organic solvent and other corrosion.
