Figure 1.The effect of shear rate on the viscosity of GLS styrenic TPEs (measured at 390°F (200°C)) To obtain information regarding the viscosity of an individual grade, refer to the product technical data sheet, available at www.avient.com or contact your Avient representative. 4 PART DESIGN General Part Design Concepts When designing a TPE part, there are a few general rules to follow: • The part wall thickness should be as uniform as possible. Estimating machine clamp capacity C = (1.5 to 3) x At 22 Barrel Capacity If possible, use a machine that utilizes 25% to 75% of the barrel shot size capacity. The feed zone temperatures should be set fairly low [typically 250°F– 300°F (120°C–150°C)] to avoid feed-throat bridging and allow entrapped air to escape.
