Where it is used

Outsoles, midsoles and injected components that must flex for years without cracking.

Interior skins, bellows, cable ducts and under-the-hood parts with tight OEM specs.

Breathable membranes, laminates, coatings and synthetic leather for apparel and mobility.

Food-contact and heavy-duty belting that survives cleaning cycles and continuous flexing.

Sealants, reactive adhesives, membranes and flooring systems with long service life.

Seals, hoses, cords and soft-touch overmoulds inside white goods and small appliances.
