Development of an ABS/PA6 Polymer Alloy for Body Panel Applications

Article of Honda R&D Technical Review Vol.12 No.1

Summary

An ABS/PA6 polymer alloy has been developed as a resin for body panels of vehicles with an aim toward overall vehicle weight reduction. Compared to conventional resins, this resin has improved surface appearance and the balance between dimensional stability and impact resistance . A “Sink Mark Evaluation Standard” was established for surface appearance, and the ratio of acrylonitrile-butadiene-styrene (ABS) resin and Polyamide6 (PA6) was adjusted to satisfy this standard. An ABS resin ratio of 50% or more was found to be effective for sink mark performance. The filler type and amount were important for the balance between dimensional stability and impact resistance with talc possessing particle diameter of 2μm being found to be effective target achievement. This resin shows a 45% weight reduction over steel panel products in the front fender.
