SILIPLAS 2073, An Efficient Anti-Squeaking Masterbatch for Quieter EV Interiors

SILIPLAS 2073 is an innovative silicone additive designed to reduce noise in automotive interiors. Specifically formulated for Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) blends, it delivers immediate and permanent anti-squeak performance, effectively preventing noise generation within the passenger cabin. This masterbatch eliminates the need for time-consuming and labor-intensive post-processing, thereby enhancing cost control, design freedom, and production efficiency.

The key emerging trends in EV place a strong emphasis on minimizing interior noise. Noise, Vibration, and Harshness (NVH) issues are more pronounced in ultra-quiet EVs and can be particularly disruptive in multi-functional self-driving cars. SILIPLAS 2073 masterbatch offers OEMs a novel method to address this challenge directly. It provides not only exceptional noise suppression but also offers high cost-effectiveness and processing efficiency.

Effectively Reduces Automotive Interior Noise

High Performance at Low Loading Levels

SILIPLAS 2073 masterbatch maintains excellent and stable noise reduction performance throughout the entire service life of the component. Test results demonstrate that at a low loading level (4 wt%), the RPN (Risk Priority Number) value is less than 3, indicating no long-term noise risk.

Furthermore, SILIPLAS 2073 masterbatch achieves an extremely low number of stick-slip events, indicating minimal occurrence of this friction-induced phenomenon during noise testing. Stick-slip, caused by friction between component surfaces, is a common source of noise. Compared to unmodified, pure PC/ABS blends, this masterbatch significantly reduces the stick-slip count.

Preserves Key Resin Properties

SILIPLAS 2073 masterbatch does not negatively impact the crucial mechanical properties of PC/ABS resins. Impact resistance at room temperature is comparable to that of pure PC/ABS resin, while tensile modulus, tensile strength, and elongation at break remain at high levels. Furthermore, adding this masterbatch results in an attractive surface appearance for PC/ABS blends, enhancing the aesthetics of the components.

Enhances Design Freedom and Processing Efficiency

Traditional noise reduction solutions often involve post-processing steps like applying anti-squeak felts, lubricants, or coatings, or replacing PC/ABS with specialized quiet resins. These post-treatments add time, cost, and complexity to the production process, can limit design freedom, and may only be feasible on simplified part geometries. Additionally, lubricants can deplete over time. Anti-squeak coatings often require manual application and post-curing, can be impact-sensitive, may develop micro-cracks that compromise performance, and can cost twice as much as standard PC/ABS. In contrast, using SILIPLAS 2073 masterbatch in PC/ABS resins simplifies the component production process and reduces overall costs.

Supplied in granule form, this new masterbatch is easy to use, simplifies processing, and imparts anti-squeak properties to molded parts immediately upon incorporation, allowing them to proceed directly to the next production step. By eliminating post-processing, it further accelerates cycle times and boosts production efficiency.

Beyond automotive interior applications like dashboards and center consoles, this new masterbatch is also suitable for components in appliances, such as refrigerator trays and storage bins, as well as in transportation applications.
