Before we begin to explore the UPVC Window, let's look at the materials that make up the main material of a plastic Window. Includes PVC resins and various processing aids.
Performance of UPVC resin
·High mechanical stability, high hardness
·good abrasion resistance
·Flame retardant and self-extinguishing
·Alkali and acid resistance
·not harmful to humans or the environment
·Low thermal conductivity
