Import Chlorinated Polyethlene Waterproofing Membrane — Buy in Bulk from Supplier in China

Chlorinated polyethlene waterproofing membrane is a sheet material based on chlorinated polyethylene that provides a barrier against water ingress. Shanghai Terra offers membranes in three thicknesses - 1.2 mm, 1.5 mm and 2.0 mm, each supplied in 1 m × 20 m sheets. The product achieves a tensile strength of 5 MPa and an elongation at break of approximately 200 %. Test data in the listing records a heat‑treatment size change of 3.11 % and a permeability resistance of 0.3 MPa for a two‑hour exposure.

Typical industry specifications for chlorinated polyethylene membranes include a density of 0.92 - 0.94 g·cm⁻3 and flexibility down to −20°C without cracking. Standard water‑permeability values are below 0.5 MPa·h, and puncture resistance is rated for water‑resistant performance. The membranes are compatible with adhesive or mechanically‑fixed installation methods and are often packaged on pallets for transport. Compliance with ISO 9001 quality management and ASTM D4435 for water resistance is common in the sector.

The membranes are used in roofing, basement waterproofing, swimming‑pool liners, reservoirs, dams and landfill leachate containment. Primary customers are civil‑engineering contractors, building developers and infrastructure firms that require long‑term durability.
