Zeotherm® 131-90B

Zeotherm® 131-90B by Zeon Chemical is a black colored, water insoluble, recyclable, high-performance thermoplastic vulcanizate (TPV) grade. It is based on polyacrylate elastomer dynamically vulcanized in a matrix of polyamide (nylon) plastic. It can withstand long-term exposure to 150°C (300°F) air & oil. This grade exhibits excellent heat resistance (sustained at 150°C & spikes to 175°C) and low temperature performance (-40°C). This grade offers excellent resistance to many mineral, synthetic motor oils, transmission fluids and greases. It is bondable to polyamides via overmolding (insert and 2-shot), hot-plate or spin welding, and co-extrusion. It is processed by blow molding. Zeotherm® 131-90B is recommended for automotive underhood boots/bellows, clean air ducts and charge air cooler ducts.
