[Beijing, 2025.11.05] – In response to growing demand for safer building materials, we are proud to highlight our fire-retardant PSK Facing, product code WPSK-4525A. This advanced version incorporates a special fire-retardant adhesive, achieving a Class 1 Fire Rating while maintaining the excellent physical properties the product line is known for.

This makes it an ideal choice for applications where fire safety is a paramount concern, without sacrificing the essential vapor barrier and strength characteristics. It retains high tensile strength and a low water vapor transmission rate (WVTR), ensuring long-lasting insulation performance for HVAC ducts, heating pipelines, and building envelopes.

"The development of WPSK-4525A aligns with our commitment to safety and quality," the product manager stated. "It provides architects and builders with a reliable, code-compliant option for their projects."

Both standard (WPSK 453A) and fire-retardant (WPSK-4525A) variants offer reliable temperature resistance from -20°C to +66°C.

PSK Facing is a composite material used in construction insulation, known for its strength and moisture resistance. The fire-retardant variant offers an additional layer of safety for commercial and industrial buildings.
