Celanese Corporation, a global chemical and specialty materials company, announced the launch of Hostaform RF, a low permeation acetal copolymer tailored for Small Off-Road Engine and marine fuel tanks, hydraulic reservoirs, and industrial bulk containers.

 “Celanese’s long history and expertise in acetal polymer formulation and processing helped us design a specific solution optimized for the rotational molding process,” said Adam Larkin, Senior Manager, Acetal Product Marketing. “This single-layer solution enables optimal tank designs without any secondary operations, thereby increasing efficiency and productivity for our customers.”

As the leading acetal copolymer supplier for automotive fuel systems, Celanese has specifically formulated Hostaform® RF to deliver an easy-to-use, drop-in solution for traditional rotational molding. The rotational molding method creates parts by placing material inside a heated, hollow, rotating mold where material is dispersed evenly.

The new RF resin system delivers the excellent mechanical and chemical-resistant properties of Celanese’s Hostaform acetal copolymer while also providing a single-layer solution versus multilayer tank systems requiring secondary treatment, such as fluorination. Hostaform RF delivers an unprecedented balance of impact and durability performance along with low fuel permeation that customers need to meet U.S. EPA regulations.
