NOXTITE® ACM Acrylic elastomers
NOXTITE® ACM grades are used whenever high temperature and oil resistance are needed in combination, typically in any powertrain configuration (gasket, hose, shaft seal, O-ring or lock-ring). Our NOXTITE® portfolio offers grades that are easy to mix and show extraordinary performance in extrusion or injection moulding.
The wide temperature range of ACM, from -40°C up to 180°C, allows for an affordable solution in various industry applications, from general industry, traditional automotive combustion engines to new oil-cooled electric drive technologies.
