Pe Pp Waterproof Membrane Oem Odm Service For Foreign Trade Export

Product Description

Polyethylene‑polypropylene fiber composite waterproof membrane, customizable width from 0.1‑1.2 m, regular thickness 0.6‑1.2 mm. With polyethylene as the core waterproof layer, it is thermally compounded on both sides with high‑strength polypropylene non‑woven fabric. Anti‑aging and anti‑UV additives are incorporated, and it is manufactured by one‑step extrusion lamination, classified as a polymer composite waterproof sheet.

Product Features

1. Aging‑resistant & durable with long service life Made of pure polymer resin without asphalt components, formulated with anti‑aging and anti‑oxidation additives. It resists pulverization, degradation and cracking under buried conditions, withstands soil acid‑alkali and groundwater corrosion, and is ideal for long‑term concealed underground waterproofing.
2. Excellent impermeability and strong vapor‑blocking performance The polyethylene core layer features a dense, pore‑free structure with integral one‑piece formation, eliminating leakage risks from membrane joints. It resists water pressure and effectively prevents water seepage and moisture back‑up.
3. High toughness & crack‑resistance, puncture‑proof and deformation‑resistant High tensile strength and elongation at break deliver outstanding membrane toughness. It accommodates minor substrate settlement and thermal expansion‑contraction deformation to avoid waterproof layer damage caused by micro‑cracks on substrates. It also offers good puncture resistance and wear resistance against external damage during construction.
4. Cold‑applied wet‑lay construction for safe operation Wet‑laid cold bonding with cement mortar requires no open‑flame hot‑melting, removing fire hazards. Installation is feasible on damp substrates, tolerating light rain and low‑temperature conditions, and suitable for poorly‑ventilated and enclosed spaces.
5. Firm bonding with cement‑based substrates to prevent water channeling and hollowing Rough polypropylene non‑woven fibers on the surface interlock fully with cement mortar. The waterproof layer integrates with building structures, reducing hollowing, delamination and edge‑lifting, and solving hidden leakage risks caused by water channeling of conventional membranes.
6. Low substrate requirements and high construction tolerance Relaxed requirements for substrate dryness and flatness. Simple construction shortens project duration and reduces rework costs.
7. Eco‑friendly and safe Formaldehyde‑free, odorless and non‑toxic. No harmful volatile substances are released during construction, with no water‑soil pollution. Applicable for drinking‑water tanks, civil air‑defense projects and residential buildings.
8. Wide range of applications Suitable for basements, roofs, kitchens & bathrooms, water tanks, sewage tanks, tunnels, foundation damp‑proofing, old roof renovation and many other scenarios.
