Spiral flow tests performed using 0.0625" thick x 0.375" wide channel at 400°F. The flexibility and elastic nature of SBC TPEs allows for the incorporation of undercuts into the part design. Due to their anisotropic nature, GLS TPEs shrink more in the flow direction than in the cross-flow direction.
