- Olefin block copolymers approved for food
contact.
Infuse thermoplastic olefin block copolymers (OBCs), unveiled by Dow Chemical, Midland, Mich., a year ago, are now reported by Dow to comply with all requirements for food contact of the U.S. FDA and the European Union. "In canisters, bottles, adhesives, foams and other food-contact applications, Infuse OBCs will deliver ......
- Impact modifiers.
AMOCO CHEMICAL CO. Polybutene improves impact resistance of many thermoplastics, including crystal PS, high-impact PS, PP homopolymer, and elastomer-modified PP. Polybutenes are clear and stable viscous polymers with little or no odor plus resistance to thermal degradation. Available in a wide range of viscosities. In PS, polybutenes can improve impact ......
