ELIX Launches Specialty Plastics to Help Reduce Noises in Automotive Cabins
Lately, ELIX Polymers, a subsidiary of Sinochem International, has developed a range of specialty grades of ABS and PC/ABS to reduce the squeaks and rattles that are generated by plastic parts in seats when interacting with other plastic parts, leather, PVC-foil or other products.
These noises can affect driver comfort as well as their perception of the quality of a car. Sound-absorbent materials are more often required by automotive OEMs to produce critical interior parts like door handles, armrests, seating parts, sunroofs, cupholders and air vents. Currently, ELIX has launched several new ABS and PC/ABS products, with which could achieve significant cost savings, as no felts, tapes or grease need to be added to reduce squeaks or rattles. These products have received recognition from a German premium automotive OEM and will be used in its cars.
These new ABS and PC/ABS materials were subjected to stick-slip tests according to VDA230-206 at testing machines from Ziegler Instruments with very positive test results. The new grades use ELIX Polymers’ base polymers: standard ABS, high heat ABS, ABS/PC or PC/ABS. As the shrinkage of the materials remains the same, current molds can be used without further need for modifications.
