Dow Performance Silicones, will introduce at Chinaplas 2018 at the DuPont stand (7.2D61) a new silicone-based technology for minimizing squeaking noise in automotive interiors and other applications. The new additive, designed for use in polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) alloys, delivers excellent anti-squeak performance without the need for post-treatments that can negatively affect cost, design freedom and processing efficiency. As the first in a new product family, this technology will reportedly expand the company’s already extensive portfolio of silicone solutions that extend properties, enhance processing and reinforce materials.
Anti-squeak additives are becoming increasingly important in the auto sector with increased penetration of quieter electric and hybrid electric vehicles.
Dow Performance Silicones will also showcase at Chinaplas 2018 two families of TPSiV silicone-based thermoplastic elastomers offering a soft, silky feel and outstanding flexibility without the need for flexibilizer additives. These materials provide strong adhesion to selected polymer substrates for overmolding applications.
Further, Dow Performance Silicones will display several other silicone additives at the DuPont stand. Two are slip additives that enhance flow properties in polyamide compounds. Dow Corning MB50-011 Masterbatch and Dow Corning HMB-1103 Masterbatch reduce coefficient of friction to improve processing and wear resistance. The third solution, Dow Corning HMB-0221 Additive, is both an anti-scratch surface agent and a processing aid. It delivers improved quality, feel and appearance in automotive interiors, and also enhances processability.
