Material:
Aliphatic Thermoplastic Polyurethane (TPU)
Market / Application:
Electronic housing
Over-moulded grips
Benefits:
High standard haptic finish
Long term resistance
Option for renewable-sourced material
|
Your Challenge:
Applications like electronics have demanding technical requirements. Existing solutions such as PVC, TPEs or standard TPUs do not meet customer needs for durable and fancy aesthetic parts in a single material…
The Solution:
Aliphatic TPU has exactly the right property profile and versatility to make it the material of choice for electronic applications. For both light & dark color parts, OEMs can rely on TPU’s high scratch resistance & UV performance. Blooming resistance, non-staining & non-yellowing appearance of aliphatic TPU versus competitive materials are illustrated in Figures 1, 2 and 3:
