TPV Waterstop

Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) which consist of materials with both thermoplastic and elastomeric properties. While most elastomers are thermosets, thermoplastics are in contrast relatively easy to use in manufacturing, for example, by injection molding. Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. The principal difference between thermoset elastomers and thermoplastic elastomers is the type of crosslinking bond in their structures.

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.

Features and Benefits

  • Quality recycled thermoplastic elastomeric rubber materials - healthy and environmental friendly.

  • Excellent resistance against chemical, ozone, oils, solvents, hydrocarbon and aggressive industrial liquids, etc. 

  • Not susceptible to ketones, esters, glycols, alcohol, and water solution of acids, salts and bases, etc.

  • High resistance to long term temperature changing ranging from -78°F to 275°F.

  • High elasticity.

  • Superior weather and UV resistance

  • Easy to butt-weld.

  • low tension and compression set.

  • Excellent dynamic fatigue resistance.

Normally, the TPV waterstops are embedded into or installed along extend of joints for preventing water and chemical liquid leaking into the joints, which is the weak point in any concrete structure. As to the changes of directions, pre-fabricated products are needed for easy installation.
