POM grades answer new interior emissions standards

07/26/2012

German automaker Daimler has implemented 50% stricter monomer emission limits for added comfort in vehicle interiors as of 2012 and this places more demanding performance requirements on resins such as acetal (POM), which emits formaldehyde. The latest low-emission Hostaform POM grades from Ticona (Sulzbach, Germany) are reportedly up to the task.

Fastening systems used in auto interiors typically employ POM components. Ticona's Hostaform POM XAP2 grades have a specification limit value of less than 2 mg/kg (2 ppm) formaldehyde emission for uncolored natural POM and less than 5 mg/kg (5 ppm) for colored or custom grades. These XAP2 grades are able to meet the stringent limit values of Daimler, which are stricter than Guideline VDA 275 of the German Association of the Automotive Industry (VDA, Frankfurt)....
