Polymers are formed differently and have inherent properties that are optimized by using best practices for their design. Don’t wait too long to select materials: Engage with a polymer supplier early on in the design process to specify the exact material attributes you need. Heat transfer capabilities of metal with design freedom and weight reduction of engineered polymers
