Two-component co-extrusion with rigid PP and soft plastic (Elastomer)

【Two-Color Extrusion with PP (hard) and Elastomer (soft)】This is an example of two-color extrusion technology, combining two different types of materials: hard PP plastic and soft elastomer. With this method, products integrating both rigidity and flexibility, such as the spine or cover of a file folder, can be created.
File clips need to ensure both durability, a secure grip, and a hinge function for flexible opening and closing. For such products, the combined use of PP plastic and elastomer material is highly suitable.
At Akebono Kasei Vietnam, we can produce two-color extruded products using hard and soft materials, from small-batch trial production to mass production, flexibly meeting customer needs.
【Specifications】
Processing Method: Two-color extrusion

Materials Used: Hard PP (polypropylene) plastic, soft elastomer (TPE, TPR)

Product Examples: File binder spines, covers with handles, opening/closing components

【Key Features】
Two-material extrusion in one pass: Combines PP plastic and elastomer in a single extrusion process

No adhesive required: Material parts bond securely while maintaining flexibility

Complex shape processing: Precisely handles curved and folded parts such as binder spines or clips

Flexible production volume: Supports production from prototypes to mass production

Japanese standard quality management: Controls dimensional and color accuracy in coordination with headquarters

【Practical Applications】
Stationery: Plastic clip components, file covers, document folders

Household goods and consumer products: Handles, anti-slip parts, frame covers

Packaging: Flexible fastening or opening/closing parts

※ This two-color extrusion technology is widely used by companies manufacturing stationery, consumer plastic products, and packaging.
With molding technology that optimally combines the characteristics of each material, we help enhance product functionality and expand design possibilities. We flexibly respond from small batches to mass production.
