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.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
LeMond Composites, founded by three-time Tour de France cycling champion Greg LeMond, is the first to license a new carbon fiber production method invented by Oak Ridge National Laboratory (ORNL) that's faster, cheaper, and greener.
This month will mark the launch of the SpeedFoiler, a super-fast, ultra-lightweight foiling catamaran that can fly short distances over water faster than other foiling designs, in part because of its carbon composite materials.
