TPV waterstop, also known as TPER waterstop, made of an alloy of rubber and plastic, acts as a fluid-tight diaphragm with excellent mechanical properties and higher chemical resistance than traditional waterstops. Without plasticizer, stabilizer or fillers, the TPV waterstops will not leech out when exposed to chemical fluids as hydrophilic waterstops.
