Low permeation POM for blow molded tanks


Celanese Corporation unveiled Hostaform LPT POM, a low-permeation and toughened polymer specifically designed for a wide range of demanding Small Off-Road Engine (SORE) applications, jerrycans and other containers.The new Hostaform POM delivers a balance of impact and durability performance that customers need to meet U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) regulations for SORE systems, according to the company. 

Hostaform S 9364 LPI is specifically designed for injection molding and S 9364 LPB for blow molding to perform in fuel systems that use ‘advanced fuels’. Traditionally, SORE fuel tanks have been molded in high-density polyethylene (HDPE), but new stringent EPA and CARB set permeation regulations require manufacturers to find a cost competitive alternative material solution. The LPT POM grades deliver an easy to use, single-layer solution that meets EPA and CARB permeation regulations and which will not degrade, scratch or wear off. Up to 25 percent reduction in manufacturing time versus other gas tank materials can be achieved.
