Product Features & Engineering Performance

  • · Molding shrinkage ≤0.12% provides excellent dimensional stability, effectively preventing warpage and ensuring good fitting.
  • · Low water absorption with outstanding waterproof performance, resisting water absorption and blistering under long-term humid bathroom conditions.
  • · Balanced mechanical properties, good impact and foot-load resistance, crack-resistant in daily use.
  • · High heat deflection temperature ≥200℃, stable against continuous hot water contact without softening.
  • · UL94 V0 flame retardancy improves fire safety for bathroom spaces.
  • · Easy to achieve glossy or matte surface finish, anti-corrosion and anti-mold, simple to clean.
  • · Integral compression molding enables complex curved shapes, lightweight structure and seamless design to avoid water leakage.
