Thermoplastic vulcanizates (TPV)
TPV offers the properties of a vulcanized rubber with the processability of a thermoplastic, making it ideal for the production of high-quality industrial hoses and innovative connection solutions.
Thermoplastic vulcanizates (TPV) belong to the thermoplastic elastomer (TPE) family.
TPEs (thermoplastic elastomers) are plastics that can be plastically deformed when heated, i.e. exhibit thermoplastic behavior, and behave mechanically like elastomers. The service properties of TPE are similar to those of rubber.
A distinction is made between:
- TPE-A (thermoplastic polyamide elastomers)
- TPE-E (Thermoplastic copolyester elastomers)
- TP-O (Thermoplastic elastomers based on olefins, mainly EPDM/PP)
- TPE-S (Thermoplastic styrene block polymers)
- TPE-U (Thermoplastic polymers based on urethane)
- TPE-V (Thermoplastic vulcanizates)
- TPZ (Unclassified thermoplastic elastomers of any other composition)
Thermoplastic vulcanizates (TPV) are special classes of thermoplastic elastomers in which dynamic vulcanization of the rubber phase takes place during melt mixing with a partially crystalline thermoplastic matrix phase at elevated temperature. They are a group of simultaneously thermoplastic and elastic plastics. They combine the low-cost processability of thermoplastics with the elastic properties of elastomers.
The best-known TPV is santoprene, which consists of ethylene-propylene-diene rubber particles (EPDM) in a matrix of polypropylene (PP).
TPV hoses (thermoplastic vulcanizates) have many uses in industrial applications. TPV hoses are mainly used as suction hoses or transport hoses. A wide variety of solids, gaseous media and liquids can be safely conveyed through them.
