Polyurethane specialist Merquinsa (Montmeló, Barcelona / Spain; www.merquinsa.com) has introduced a new family of “Pearlthane” ECO TPU grades produced with “Cerenol” renewably-sourced polyol from DuPont (Wilmington, Delaware / USA; www.dupont.com), in a strategic collaboration between the two companies.

Merquinsa said the grades complement existing “Pearlthane” ECO polyester and polyether ranges based on renewable sources, designed for a range of areas of application including footwear, sport and leisure, electronics and automotive. It said that “Cerenol” polyols are ideal soft segments for thermoplastic polyurethane elastomers, offering high performance with the added benefit of being environmentally responsible.
