manufacturing process is used to make  PVC foam board?
PVC foam board/sheet is manufactured using Celuka Foam Extrusion, Simulation-Celuka foam Extrusion and Free Foam Extrusion. Those three difference processes provides Celuka, Rigid and Free Foam of PVC foam board to meet different applications' needs, while competitors are only able to offer PVC free foam boards or Simulation-Celuka products.
Is Cellular PVC Environmental Friendly?
All  products including Cellular PVC products and PVC mouldings are 100% recyclable. The benefits of recycling PVC building materials include reduced landfill waste, reduce embodied energy, and reduce the impacts from harvest or mining.
Most importantly, recycling saves energy and reduces pollution. This could help slow down global climate change, another environmental problem caused by burning fossil fuels like oil and gas-ultimately this aids in reducing our carbon footprint.
PVC recycling helps the environment by slowing down the rate at which we fill our landfills. This will reduce the amount of landfills needed and with fewer landfills we can have more space for people to farm, live, and work.
