Material:
Aliphatic Thermoplastic Polyurethane (TPU)
Market / Application:
Automotive interiors
Benefits:
High standard haptic finish
UV & staining resistance for light colors
Option for renewable-sourced material
|
Your Challenge:
Automotive interiors designers are constantly looking for improved aesthetics. Existing solutions such as PVC, TPEs or aromatic TPUs do not meet customer needs for light colors, durable and high class finish aesthetic parts.
The Solution:
Aliphatic TPU has exactly the right property profile and versatility to make it the material of choice for luxury automotive interior applications. For both light & dark color parts, OEMs can rely on Aliphatic TPU's excellent balance of scratch, staining resistance & UV performance. Blooming resistance, non-staining & non-yellowing appearance of aliphatic TPU versus competitive materials are illustrated in Figures 1, 2 and 3:

In addition, Merquinsa's Pearlthane® ECO new green TPU technology has widened material options above, for automotive interiors with renewable-sourced grades which offer virtually the same benefits as standard TPU from petroleum-based sources.
