Wittenburg BV Resources
We developed several Cawiton® grades to generate good adhesion on a broad scale of a-polar and polar polymer substrates. This is done with two component moulding techniques. 2K moulding or the less preferable overmoulding technique.
We have developed Cawiton® grades with high medical quality to support pharmaceutical companies with their fluid handling components. Our TPE grades are designed for aseptic welding connections and sealing disconnection.
Our extrusion grades are suitable for sterilization by gamma irradiation and autoclave.
