Pro Tips
Always test TPE adhesion to your specific substrate under actual molding conditions - adhesion can vary significantly between similar plastic grades.
Request compression set data at your actual operating temperature, not just standard test conditions, as performance varies greatly with temperature.
Consider TPE shore hardness tolerance - ±5 Shore A points can significantly impact feel and sealing performance in critical applications.
Evaluate multiple TPE types (TPU, TPV, SEBS) for your application - the optimal choice depends on your specific property priorities and cost targets.
