PHILADELPHIA (Oct. 11, 9:55 a.m. ET) — Arkema Inc. has launched a new grade of its Durastrength-brand impact modifier for use with polycarbonate/ABS blends.
Philadelphia-based Arkema commercialized the new grade of the acrylic-based modifier earlier this year. It's being aimed at auto and appliance markets, research scientist Jason Lyons said by phone.
Automotive uses include interiors, where good cold-temperature impact performance is needed. In appliances, it can be used in home office devices and business machines, as well as drills and other tools. The material is being produced at an Arkema plant in Axis, Ala.
Previously, the company had only one grade of Durastrength aimed at PC/ABS applications, Lyons said. Arkema is working on two additional grades in that category — one to be commercialized by year's end year and one in 2012.
The new modifier grade can be used in percentages of 1-7 percent and in some cases can improve the flow of PC resin by as much as 100 percent without sacrificing strength performance, Lyons added.
The new grade was designed with sustainability in mind, since many PC/ABS users are now using PC regrind as a means of cutting costs and making the best use of traditional materials.
“Sustainability was a focus from the beginning,” Lyons said.
Arkema's plastic additives, in addition to Durastrength, include Clearstrength and Biostrength impact modifiers, Vioflex-brand soybean oils and Luperox-brand organic peroxides.
Arkema Inc. is the North American business unit of Arkema Group of Colombes, France. The company is a major producer of acrylic resin and sheet sold under the Plexiglas and Altuglas trade names.
