Recorded Wednesday, May 23 – Presented by Dow Performance Silicones
A new silicone additive immediately and permanently eliminates squeaking in polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) blends used in automotive interior parts, appliance parts and other applications. The new additive – DOW CORNING™ HMB-1903 Masterbatch – solves the design, cost and productivity challenges of post-treatments, and retains the mechanical properties of the resin.
High Performance at Low Loadings
Noise, vibration and harshness (NVH) can be a major issue in auto interiors. NVH generated by stick-slip action in PC/ABS parts is more noticeable in ultra-quiet electric vehicles, and more intrusive in self-driving cars that will be used for entertainment and relaxation, not just transportation.
The new DOW CORNING™ HMB-1903 Masterbatch delivers high anti-squeak performance at low loadings (typically 4 wt%), and remains stable throughout the useful life of the part. It can also replace time-consuming, labor-intensive post-treatments such as coatings, lubricants and felts, and expensive specialty resins.
- Higher productivity/faster cycle times by avoiding secondary operations
- Expanded design freedom by enabling complex geometries
- Retention of impact, tensile strength/modulus and elongation properties
- Attractive surface appearance
The Dow Performance Silicones webinar will describe automotive trends behind the demand for better anti-squeak solutions, and compare the new silicone technology with traditional approaches.
Topics will include:
- How our silicone technology addresses stick-slip phenomena that cause squeaking
- Product test data on RPN and impulse performance, and mechanical properties
- Technical guidance on using the new additive
