PVC Compounds for Weather Resistant Applications - 2 MoistureRain and humidity are the two main contributors to moisture. Humidity keeps the material constantly moist, which can cause growth of bacteria as well as plasticizer leaching. Rain has a washing and impacting effect that could be detrimental to the material.WindWind is a carrier of particles such as dust, gases and moisture that can contribute to weathering effects on the…

Knowledge Of The Use Of Flame Retardants In general, the flame retardant mechanisms of bromine and chlorine systems are similar. At high temperature, the carbon-halogen bond in halogen-based flame retardants will be damaged, releasing halogen free radicals, which can effectively capture free active free radicals generated by thermal degradation of polymer materials, and can effectively reduce the concentration of free …

Fire Protection Effect Of Intumescent Steel Structure Fireproof Coating On Steel Barrier function. The high-expansion carbonized layer can effectively isolate the protected steel structure from air and heat sources, thereby effectively reducing the surface temperature of the steel structure and prolonging the support time of the steel structure in a fire. The heat absorption, softening, melting and expansion of the polymer coating, the physical change of the…
