Thermoplastic vulcanizates (TPV) are dynamically vulcanized alloys consisting mostly of fully cured EPDM rubber particles encapsulated in a polypropylene (PP) matrix. They are part of the thermoplastic elastomer (TPE) family of polymers but are closest in elastomeric properties to EPDM thermoset rubber, combining the characteristics of vulcanized rubber with the processing properties of thermoplastics. There are almost 100 grades in the S portfolio that are used globally in the automotive, household appliance, electrical, construction, and healthcare markets.
Applications:
Automotive components
TPV (thermoplastic vulcanization) is used in weather seals, underhood and under-car applications, and interior components. In weather seals, TPV is used as a lightweight alternative to thermoset rubber materials in semi-dynamic and static parts, while in underhood and under-car applications it is well-suited for air ducts, tubing, molded seals, grommets, suspension bellows, cable jacketing, plugs, bumpers, and many other parts. This is due to its sealing performance and resistance to extreme temperatures, chemical exposure, and harsh environments.
Building and construction products
In commercial glazing seals, TPV is used for curtain walls, storefronts, architectural windows, and skylight weather seal applications. It is also commonly used in residential glazing seals due to its low air and water infiltration ratings for the life of window and door systems.
For road and rail construction projects, TPV is used for bridge and parking decks, water stops, rail pads, and other applications.
In plumbing,TPV is used to create long-term seals, gaskets, and grommets that are resistant to flex fatigue, harsh temperatures, and chemicals. It can be used in a variety of sealing applications including pipe seals, bridge expansion joints and curtain walls, parts for potable water, and pipe seals for sewer and drainage.
Household product parts
TPV is used in washing machines, dryers, dishwashers, refrigerators, small appliances, and floor care. Its properties enable it to be used in a range of parts including pump seals, hoses, couplings, vibration dampeners, drum rollers, knobs, and controls.
Electrical components
TPV is used in wiring connectors to make watertight seals with electrical and thermal resistance, insulation for high voltage applications, and flexibility even at low temperatures to −60 °C.
It is used in industrial wire and cable connectors and low-voltage industrial cable applications that include insulation and jackets, in addition to consumer wire and cable use.
For electrical components, TPV can be used for watertight seals, enabling connectors to be insert-molded to cable jacketing, producing a single integral part.
