PolyOne, a leading specialty compounder, launched a line of biopolymer compounds at this week’s National Plastics Exposition in Chicago. Patent-pending Resound compounds will be formulated with a minimum of 30 percent bio-derived content, and as much as 70 percent, Dr. Cecil C. Chappelow, vice president of innovation for PolyOne, told Design News in an interview. The biobased polymers that maybe used include PLA, PHB, PHBV as well as biopolyesters. Dr. Chappelow said he could not disclose the traditional plastics that PolyOne is studying. One logical candidate, however, is polycarbonate. Resound grades feature heat resistance (HDT) up to 120C (248F) and impact resistance up to 53 J/m (12 ft-lb/in). PolyOne’s goal is to develop bio compounds that will meet or exceed performance requirements for durable applications such as computer laptops, cell phones and auto components. Dr. Chappelow said the new compounds will process as well as traditional compounds.
PolyOne has developed a large portfolio of bioproducts, ranging from special colorants to thermoplastic elastomers. PolyOne is even working on a bio-based plasticizer that could replace phthalates in construction applications. The goal is to develop drop-in replacements that are competitive on a performance and total cost basis. Meanwhile, PolyOne retains a strong commitment to vinyl compounds. At a press conference today, PolyOne showed a PVC appliance part with a metallic appearance. The pre-colored part represented a significant savings over a painted part.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
