Polyplastics Group has introduced a new DURACON® polyoxymethylene (POM) grade which delivers improved diesel fuel resistance to produce injection molded automotive fuel system components.
The new material complements Polyplastics’ flagship DURACON® POM portfolio which is already widely used for automotive fuel system components due to its superior mechanical properties, heat and fuel resistance, and excellent moldability.
Superior Performance and Reduced POM Decomposition
DURACON® H140DR offers superior performance over competitive materials and is targeted for global markets.
DURACON® H140DR has superior resistance over POM decomposition compared to other improved diesel fuel resistant POM from competitors and a standard material.
DURACON® H140DR has a higher melt flow rate (MFR) than standard grade M90-44, resulting in good formability. It is also denser, with smaller crystal size, and thus has a high degree of crystallization compared to standard grade M90-44.
The new grade has the same level of creep-fracture properties versus competitive materials and appears to have enough long-term mechanical resistance properties as well.
Environmental stress fracture testing reveals that DURACON® H140DR has high resistance to external factors such as acid rain and various acidic solvents used in cars.
