The introduction of the new Hostaform PTX POM series is one of several Celanese is scheduled to make at booths A07 and B07 in Hall 06 during K 2013. The new series delivers unique elastic mechanical properties that provide customers with a technical alternative to traditional thermoplastics used in automotive in-tank fuel and vapor lines. Hostaform PTX POM: • Meets fuel system requirements for flex fuels and highly aspirated engines designed to reduce CO2 emissions • Challenges existing materials — polyamide PA11-P and PA12-P — since it leaves no undesirable oligomer clogging substance in the fuel, which can affect engine performance “Celanese polymer scientists developed the new Hostaform PTX series with a proprietary POM hybrid technology that improves the acetal copolymer coupling strength to modifiers and other additives,” said Oliver Juenger, Hostaform POM product development Celanese “The result is an enhanced package that differentiates Hostaform PTX POM from other impact modified thermoplastics.”
The new Hostaform PTX POM series, a member of the impact modified POM product family from Celanese, is suitable for both injection and extrusion molded fuel related applications that require enhanced mechanical characteristics in such a demanding environment: • Similar mechanicals to PA11-P and PA12-P • Excellent toughness and resilience: -40 degrees Celsius (-40 degrees Fahrenheit) • Meets temperature performance demands: from -40 degrees Celsius to 65 degrees Celsius (-40 degrees Fahrenheit to 149 degrees Fahrenheit) • Broad chemical resistance: resistant to environmental stress cracking • Low moisture absorption — good dimensional stability • Easy to process (no pre-drying needed) • Meets in tank material requirements — burst pressure performance • Offers potential cost savings “We are excited with the opportunities for Hostaform PTX POM,” Oliver said. “Not just in automotive in-tank fuel and vapor lines but in pneumatics and paint-line applications.”
