Polyethylene Closed Cell Foam Board Has a Sealed Porous Structure

Polyethylene closed cell foam board

Polyethylene closed cell foam board is a joint waterstop material made from a mixture of high-pressure polyethylene particles, crosslinking agents, foaming agents, and other raw materials. Its production process includes internal mixing, open mixing, vulcanization, and high-temperature mold shaping. Polyethylene closed cell foam board features a unique closed-cell bubble structure, with an appearance of uniformly distributed honeycomb-like holes, capable of tightly bonding with cement adhesives, demonstrating excellent waterproof and sealing performance.
