Largest sealing programme.
Made in Germany.
The component - perfect with the right seal. And that is our passion. With in-house toolmaking, rapid prototyping, a wide range of materials and the full commitment of more than 100 employees. We develop solutions - on 17 extrusion lines and with the highest technical standards. Knowledge and expertise become quality - in use throughout Germany and internationally. That is GfA!
Sometimes more is simply required: Co-extruded sealing profiles combine two material components in one profile, providing optimum product properties for special applications. During the production process, two material types are permanently bonded together. In window sealing profiles, for example, the softer material ensures optimum elasticity and sealing performance, while the harder component provides stable retention. Whenever maximum elasticity and flexibility are required, even at extreme temperatures, silicone rubber comes into play – available as a co-extruded solution on request. Put your trust in the expertise of our GfA-SiliTech.
