Critical Precautions
1. Overmolding Application: For two-shot overmolding onto rigid substrates (e.g., PP, ABS), ensure the use of a bonding grade compatible with the specific substrate. The substrate surface must be clean and at an appropriate temperature.
2. Shrinkage: TPE typically has higher shrinkage than rigid plastics. This must be fully considered in mold design (typical range: 1.5%-3.0%).
3. Flowability: Although flow is good, gate and runner design should still be optimized for filling complex thin-walled parts.Purge Suggestion
Routine purging with PP or HDPE is sufficient. When switching from a higher-temperature material, reduce the temperature to this material's processing range before purging.
