Outgassing of TPEs can cause multiple aesthetic defects. Vent depths for TPEs are typically between 0.0005” and 0.001”.  Most GLS TPE materials replicate the mold surface fairly well.

For styrenic-based TPEs, the gate depth (D) should be 25-35% of the TPE component’s wall thickness at the gate entrance; 35-50% for urethane-based TPEs. For styrenic-based TPEs, the gate depth (D) should be 25-35% of the TPE component’s wall thickness at the gate entrance; 35-50% for urethane-based TPEs. Improper TPE shut-off design.

TPE-1A is translucent and TPE-1B is opaque. TPE-2 TPE-2 materials are opaque and their base chemistries are different from TPE-1. The results confirm that TPE-1A, B and TPE-2B are truly the “universal overmolding TPEs.”

The adhesion is categorized based on adhesive failure (A)- if no TPE residue is left on the substrate, or cohesive failure (C)- if the failure is in TPE. Design Considerations The material requirements of bondable TPE’s are different from conventional TPE’s and it is the same for designing parts. Prevent the TPE from flashing over areas on the substrate. 4.

Generally, GLS TPEs will flow much further in thinner walls than other types of TPEs. Coloring SBC TPEs have inherently superior color than most other TPEs. Use a lower viscosity TPE.
