Co-extrusion is a technology that combines two materials into a single component within a single extrusion process. Two extruders are connected in series to supply the die and enable their respective polymer materials to be co-extruded along corresponding channels, producing an extrudate composed of both materials. Homogeneous materials, such as TPV and polypropylene, can be seamlessly blended. Multi-layer extrusion is an effective method for combining rigid and flexible materials. Typically, a high‑hardness section—such as thermoplastic elastomer (TPV)—serves as the structural support of the part, while a lower‑hardness material provides flexibility. This approach is commonly used in sealing applications, where the sealing zone is softer, allowing the compliant material to…
Co-extrusion is a technology that combines two materials into a single component in a single extrusion process. Two extruders are connected in series to supply the die and guide their respective polymer materials through separate channels, enabling them to be co-extruded together and producing a composite extrudate. Homogeneous materials, such as TPV and polypropylene, can be seamlessly blended. Multi-layer extrusion is an effective method for combining rigid and flexible materials. Typically, a high‑hardness section—such as thermoplastic elastomer (TPV)—serves as the structural support of the part, while a lower‑hardness material provides flexibility. This approach is commonly used in sealing applications, where the sealing zone is softer; the compliant material can be compressed to achieve a tight seal. Moreover, during flow‑balance optimization, substituting a higher‑hardness TPV for polypropylene as a stiffening material simplifies the design.
