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.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
