Houston, Texas - Fei Tan, global head of business development for Rhein Chemie's Engineering Plastics Division, detailed the benefits of the firm's new family of hydrolysis stabilisers in a paper given at the Polyurethanes 2010 Technical Conference October 11-13, 2010, in Houston.
The paper, titled An additive approach to extending the performance ranges of conventional polyester, polyurethane adhesives, discussed how the stabilisers prolong the life of many types of polyurethane adhesives, particularly in the flexible packaging, electrical, electronics, and shoe sole markets,
Rhein Chemie says. Tradenamed Hycasyl, they are especially useful for applications where higher temperatures and moisture levels are encountered, according to a new release from the Chardon, Ohio-based subsidiary of the German firm.
Lab tests show them to have up to 13 times longer adhesive life and up to twice the adhesive strength of unstabilised adhesives, the statement added.
"One of the key benefits Hycasyl stabilisers offer formulators is the opportunity to enter new markets," said Bruce Ernst, global head of sales & marketing for Rhein Chemie's Engineering Plastics Division. "Not only can they extend the performance range of high-performance adhesives, they can also allow formulators to push medium-performance adhesives into more demanding higher-performance applications - in a cost-effective way," he claimed.
Currently, Rhein Chemie offers four Hycasyl grades covering a range of temperature, solubility and application conditions. The choice of product is dependent on the end-use market, processing conditions and polymer backbone type, the company statement concluded.
Rhein Chemie develops, produces and sells products for various polymer industry segments, including catalysts, crosslinking agents and stabilisers used in the manufacture of flexible and rigid polyurethane foams.
The firm is headquartered in Mannheim-Rheinau, Germany, and has about 800 employees working in offices and production facilities in Europe, Asia and North and South America. It is a wholly owned subsidiary of the Lanxess Group based in Leverkusen, Germany.
