HOUSTON (ICIS news)--US compounder PolyOne has released its first commercial bisphenol A (BPA)-free compounds made with Eastman Chemical's Tritan copolyester, the company said on Monday.

PolyOne and Eastman Chemical signed a marketing agreement in June. Under the agreement, PolyOne would combine Eastman's copolyester with performance-enhancing additives to develop fully compounded systems.

PolyOne is marketing the compounds under the brand name, Edgetek.

PolyOne was pleased to have finalised a commercial offering so quickly, according to Craig Nikrant, vice president.

“This set of Edgetek high-performance compounds, which are based on Tritan copolyester resins compounded with performance enhancing additives and reinforcers, will be particularly notable for their unique combination of physical properties, durability, chemical and heat resistance, high-impact resistance, design flexibility and processing ease,” Nikrant said.

PolyOne cited numerous processing advantages within the Tritan copolyester relative to other transparent polymers, saying that the new compounds were ideal for such products as small kitchen-appliances, reusable food containers, and infant-care items. Those products could be subject to heat and chemical attack through repeated dishwasher cycles.

BPA is a necessary ingredient in polycarbonate (PC) products, with much of the controversy surrounding PC food-contact containers for infants.

Chemical companies have long been under pressure to create BPA-free compounds due to studies showing at least hints of links to diabetes, cancer and developmental problems in foetuses.

While some studies have said that BPA causes no detrimental effects, the public is still concerned about the chemical.
