Applications

ELASTOMERS

ADDITYS offers a range of stabilisers that allow to control the vulcanisation process of hydrocarbon rubbers, and reduce material deterioration resulting from oxidation. Such additives are used in the production of windshield wiper blades and timing belts.
ADDITYS' chain extenders are used in numerous polyurethane and polyurea formulations, to fabricate among others: rollers, car parts and leisure goods, either by cast process or by reactive injection moulding (RIM).

ETHANOX® 4702

ETHANOX 4702 (CAS: 118-82-1) is a multi-ring phenol antioxidant with superior performance. Its high effectiveness at reducing the formation of acidic and insoluble oil oxidation products makes of ETHANOX 4702 the antioxidant of choice for very demanding applications, including but not limited to engine oils, aviation lubricants, and automatic transmission fluids.
