NEWS 3 Sealing Technology February 2007 Heat resistance to 175°C, hot oil resistance and also rubber-like flexibility are available from a new grade of thermoplastic elas- tomer, Zeotherm 100-60B, from Zeon Chemicals LP. This material is designed to offer the flexibility of conventional thermoset rubber such as ethylene acrylic (AEM) but provide the processing advantages of a thermo- plastic, while not compromising on the feel and function of auto- motive parts. It is based on a poly- amide plastic phase, which allows for over-moulding and welding to rigid polyamide parts. Tests indicate that the flex mod- ulus is similar to thermoset rubber, a value of 8.5 MPa being recorded – compared with 7.5 MPa for a similar hardness AEM thermoset compound. This new material has a durometer of 60 Shore A com- pared with previous materials which were limited to 70 to 90 Shore A. Applications are expected to include dust and dirt shields, iso- lator cuffs, steering system seals, suspension components and grips for industrial equipment. Long- term testing indicates that it can resist continuous exposure to 150°C in both air and hot engine oil in excess of 1000 hours, with short term intermittent exposure to 175°C.

Heat resistance to 175°C, hot oil resistance and also rubber-like flexibility are available from a new grade of thermoplastic elas-tomer, Zeotherm 100-60B, from Zeon Chemicals LP.

This material is designed to offer the flexibility of conventional thermoset rubber such as ethylene acrylic (AEM) but provide the processing advantages of a thermo-plastic, while not compromising on the feel and function of auto-motive parts. It is based on a poly-amide plastic phase, which allows for over-moulding and welding to rigid polyamide parts.

Tests indicate that the flex mod-ulus is similar to thermoset rubber, a value of 8.5 MPa being recorded – compared with 7.5 MPa for a similar hardness AEM thermoset compound. This new material has a durometer of 60 Shore A com-pared with previous materials which were limited to 70 to 90 Shore A.

Applications are expected to include dust and dirt shields, iso-lator cuffs, steering system seals, suspension components and grips for industrial equipment. Long-term testing indicates that it can resist continuous exposure to 150°C in both air and hot engine oil in excess of 1000 hours, with short term intermittent exposure to 175°C.
