Rubber Moulding vs TPR and TPV Moulding
While traditional rubber moulding (using thermoset rubbers like EPDM or natural rubber) offers excellent elasticity, compression set, and durability for demanding applications, TPR (Thermoplastic Rubber) and TPV (Thermoplastic Vulcanizate) moulding present significant advantages for modern manufacturing.
Unlike thermoset rubbers that undergo irreversible chemical cross-linking during curing, TPR and TPV are thermoplastic elastomers, meaning they can be melted, moulded, and re-melted multiple times. This key difference translates to shorter cycle times, increased production efficiency, and the valuable ability to recycle manufacturing scrap, significantly reducing material waste and production costs.
TPVs, in particular, offer enhanced performance characteristics closer to traditional rubber, including superior heat resistance, chemical resistance, and excellent compression set, making them ideal for applications requiring high durability and resilience while benefiting from the processing advantages of thermoplastics. Choosing between these materials hinges on specific application requirements, balancing performance needs with cost-effectiveness and sustainability goals.
