Co-Extruded Profiles with Multi-Material Layering for Sealing & Trim

Product Summary

Our co-extruded profiles combine two or more materials in a single extrusion, typically a rigid substrate (PVC, ABS, PP) with a flexible sealing lip (TPE, silicone). This integrated design eliminates assembly steps and enhances sealing performance. Widely used for automotive weatherstrips, window gaskets, and decorative trims.

Key Selling Points

• Integrated Sealing: Rigid base with flexible lip ensures secure fit and weatherproofing.
• Reduced Assembly: Single part replaces multi-component assemblies.
• Color & Material Match: Each layer can be colored to specifications.
• Length up to 6000mm: Continuous profiles minimize joints.
