Co-extrusion Additives and Plastic Compounds

Co-extrusion

Co-extrusion is an extrusion process in which two or more materials are extruded through a single die. In this process each thermoplastic material is melted in a separate extruder. The molten materials are then introduced simultaneously in a single die, where they come together to form a unified structure. As the materials merge, they bond into a single solidified product before entering the cooling stage. The main advantage of coextrusion is that each material maintains its properties. To optimize this process for specific applications, various additives and plastic compounds, like tie resins and chain extenders, can be incorporated.

Additives and plastic compounds used for co-extrusion

The Compound Company offers multiple Yparex and EcoForte products for the co-extrusion process, such as tie resins with adhesion to materials like PE, PA, PU, EVOH, and aluminium, and PET or PLA based chain extenders. For sustainable applications we also have bio-based tie resins for co-extrusion.

Applications of co-extrusion

Co-extrusion has a broad range of applications, like packaging, mechanical recycling, building and construction, pipes, wire and cabling.
