Key Differences Between EPDM and Thermoplastics in Injection Molding
In the world of injection molding , selecting the right material is critical to a product's performance, durability, and cost-effectiveness. Among the many material options available, EPDM rubber and thermoplastics are two widely used categories—but they serve very different purposes and behave quite differently during the injection molding process. This comprehensive guide explores the key differences between EPDM and thermoplastics in injection molding, comparing their physical properties, molding behavior, typical applications, cost considerations, and more. Whether you're a product designer, engineer, or manufacturer, understanding these differences can help you make better decisions when specifying materials for molded parts. 1. What Is EPDM? EPDM stands for Ethylene Propylene Diene Monomer , a type of synthetic rubber . It’s known for excellent weather resistance, flexibility, and resilience. EPDM belongs to the family of elastomers , which are polymers with ...
