Polyvinyl chloride (PVC) is a low cost polymer material, and it is easy to process.
However, when it burns, it produces a lot of smoke, decomposes toxic and corrosive gases, suffocating, and is the main cause of death in fires. The application of fine aluminum hydroxide to PVC effectively overcomes the above shortcomings.
Fine aluminum hydroxide surface-treated with coupling agent can also significantly reduce the smoke density of plastics, and the mechanical properties of the material are just a little reduced. It is an excellent flame retardant and smoke suppressant.
