Aardvark Polymers has expanded its line of acetal resins suited to rotational molding.
Aartel resins are now available in general-purpose, impact-modified, static-dissipative and antimicrobial grades. They complement Aartel 1000, a premium grade of toughened copolymer introduced by the Lambertville, N.J., company in early summer.
Unfilled Aartel acetals have very low fuel permeation rates, according to Aardvark. The resins may be steam-sterilized and they are colored without heavy metals for potential applications in food and medical markets.
Aardvark's expanded line coincides with the firm's capacity expansion to 2 million pounds per year. The company plans another expansion in November accompanied by its debut of glass-fiber-filled and long-glass- fiber-reinforced acetal grades. Aartel resins are made from acetal copolymers supplied by Ticona Engineering Polymers. Other engineering resins for rotomolding under development at Aardvark include nylons 6 and 6/6 and polyesters.
