Nearly 50 new PVC compounds that incorporate new biobased, non-phthalate plasticizers and other formulation enhancements that address the “green” concerns of wire and cable users will be introduced commercially in the first quarter of 2013 by Teknor Apex Co., Pawtucket, R.I.
A number of major businesses have changed hands recently.
A new acrylic cell stabilizer for rigid PVC foam sheet is said to reduce additive usage by 10% to 15% or else produce lower-density foam with performance equal to higher densities.
New acrylic-based impact modifiers are optimized to address different aspects of vinyl window profile performance.
Dow Chemical Co., Midland, Mich., has signed a definitive agreement to acquire Rohm and Haas of Philadelphia.
Plastics are going “green,” but they will need some help to get there. Biodegradable polymers derived from renewable resources are attracting lots of interest and publicity, but that enthusiasm is counterbalanced by persistent questions of availability, cost, performance, and processability. All these issues are inter-related: Increasing demand will lead to more capacity, which will presumably lead to lower prices. But the foundation is market demand, which ultimately depends on whether biopolymers will have the performance properties and processability to compete with existing non-renewable plastics.
A proprietary impact modifier is said to toughen PLA (polylactic acid) biopolymer without sacrificing clarity.
Wood-plastic composites, or WPCs, are already a 1.3-billion-lb market and are growing at 20% annually.
Making high-strength composites less expensively was the dominant theme of the recent Composites 2003 Show in Anaheim, Calif., sponsored by the American Composites Manufacturers Association (formerly the Composites Fabricators Association). Among the stars of the show were the vacuum infusion process (VIP), along with a number of new resins—including several non-traditional material chemistries—and new initiators. (New reinforcements, fillers, additives, and equipment will be covered in future articles.)The closed-mold VIP method is attracting a growing following from spray-up fabricators who want to meet the EPA’s MACT (Maximum Achievable Control Technology) standards for hazardous air-pollutant (HAP) emissions, which take effect in 2006.
