Standard general wpc sheet formula only meets dry indoor decoration usage demands, outdoor wall mounted wpc sheet faces long term sunlight rain and temperature alternation, requiring customized auxiliary agent proportion adjustment to avoid fading cracking and surface film shedding problems.
General indoor wpc material adds low proportion anti uv auxiliary, while outdoor dedicated wpc sheet formula increases light stabilizer content by double standard dosage. Extra anti uv ingredients lock pigment molecules inside composite material, preventing wood grain color fading after years of outdoor sunlight continuous irradiation.
Outdoor building wall wpc sheet raises waterproof additive mixing ratio inside wpc material matrix, shrinking internal raw material micro pore structure to block rainwater infiltration. Indoor wpc sheet does not need high dosage waterproof agent to control overall raw material production cost for dry interior decoration projects.
Outdoor weather resistant wpc sheet adopts high temperature resistant composite stabilizer formula for co extrusion sheet production. Long term outdoor temperature fluctuation accelerates material aging, high stability auxiliary agent slow down molecular decomposition speed and maintain flat smooth wpc sheet panel shape for more than ten years.
Custom outdoor weather resistant wpc sheet must cooperate with matched anti uv pvc film to complete full surface pvc lamination. Adjusting internal wpc material formula alone cannot realize complete weather protection, matched high performance pvc film forms double isolation barrier together with modified wpc sheet substrate against outdoor harsh climate erosion.
