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.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
