TPA (Thermoplastic Polyether Polyamide) is a special block polymer based on polyamide.
A characteristic of TPA is that it contains no plasticisers and the material remains flexible at low temperatures.
Like TPU, TPA is resistant to oils and greases. This is one of the reasons why TPA is regularly used in industrial applications and for dynamic seals.
Because TPA is based on PA12, this material is very suitable for high temperatures.
