Merquinsa, DuPont invest in renewables
Materials firms Merquinsa of Barcelona, Spain, and DuPont Co. of Wilmington, Del., have struck a deal to make products based on renewable resources.
The arrangement, announced June 23 at NPE2009, calls for Merquinsa to produce a new family of Pearlthane Eco-brand thermoplastic polyurethane based on DuPont's Cerenol-brand renewably sourced polyol. Merquinsa already makes Pearlthane Eco polyester and polyether products based on renewable resources.
The new TPU materials are expected to be used in a wide range of footwear, sport and leisure, electronics and automotive applications. Smith Optics Inc. is using a grade of Pearlthane Eco Bio TPU with 44 percent renewable content in its Evolve ski goggles, Merquinsa said. Renewable content for the full range of Bio TPU can range from 20-90 percent.
In the footwear market, Brooks Sports Inc. plans to use another grade of Pearlthane Eco in molded parts in upcoming designs, officials said.
Pearlthane Eco made with DuPont Cerenol shows outstanding properties comparable to petrochemically based TPUs, Merquinsa officials said.
Ray Miller, Cerenol global business manager for Wilmington, Del.-based DuPont, described Merquinsa as a highly innovative polyurethane producer with a proven track record for introducing sustainable offerings.
Evonik booth gets medical attention
A stream of medical product firms visited the NPE booth of Evonik Degussa Corp. of Parsippany, N.J., according to Jeff Smith, technology and market development director for high-performance polymers.
Evonik's Vestakeep M polyetheretherketone materials comply with the ASTM F2026 standard for short-term surgical implants. The range includes medium-viscosity Vestakeep M2G, high-viscosity M4G and powder-grade M4P.
PEEK is being used in medical products as an alternative to metals and other materials. Evonik said the material is biocompatible, and resistant to chemicals, X-rays and steam sterilization. It also is strong and has good wear and impact resistance.
