Anti-squeaking Masterbatch, PC/ABC material noise reduction solution to solve the noise problem of auto parts and home appliances

Noise pollution is one of the main problems of environmental pollution. Among them, the car noise generated in the process of car driving accounts for a very important part. Car noise, that is, when the car is driving on the road, the engine, the dashboard, the console and other interior, etc., the sound that seriously affects human health.

In recent years, new energy vehicles have grown significantly and rapidly occupied a large part of the market, out of the impact of engine noise, automotive interior parts noise pollution phenomenon has become particularly prominent and difficult to ignore, the impact on People's Daily driving life is also increasing. It can be seen that reducing the noise of automotive interior parts is a major problem that the automotive industry must overcome.

In terms of automobile noise reduction, the traditional noise reduction methods mainly include pasted flannelette, non-woven fabric or tape; Coated with lubricating oil and grease; Rubber gasket; Screw fixing, etc., usually has low efficiency, unstable noise reduction performance, expensive, complicated processing technology and other problems. In addition, there is an added noise reduction masterbatch [https://www.siliketech.com/anti-squeaking-masterbatch/], which can effectively avoid the above problems and achieve a good noise reduction effect.

SILIKE Anti-squeaking Masterbatch [https://www.siliketech.com/anti-squeaking-masterbatch/], the essence is a special polysiloxane that provides excellent long-lasting noise reduction performance for PC/ABS materials at a low cost. In terms of noise reduction of automotive parts, it has the following characteristics:

- Excellent noise reduction performance: RPN

- Reduce stick and slip.

- Instant, long-lasting noise reduction features.

- Low coefficient of Friction (COF).

- Minimal impact on key mechanical properties of PC/ABS (impact, modulus, strength, elongation).

- Low addition (4wt %).

- Easy to handle, free-flowing particles.

Typical test data:

SILIKE Anti-squeaking Masterbatch has excellent performance in automotive noise prevention, with the advantages of minimizing intrusive noise and vibration, low additive amount, and improved cost control. Here's a comparison of some lab test data.

Figure 1 shows the comparison of noise risk index (RPN) test data. If RPN is lower than 3, noise is eliminated and there is no long-term application risk. It can be clearly seen from Figure 1 that when the addition amount of SILIPLAS2073 is 4wt%, the RPN is 1, and the noise reduction effect is excellent.

Figure 2 shows the variation of stick-slip test pulse value of PC/ABS after adding 4%SILIPLAS2073. The test conditions are V=1mm/s and F=10N.

FIG. 3 shows the comparison of stick-slip state and noise before and after adding 4% SILIPLAS2073.

It can be seen from the graphic data that the stick-slip test pulse value of PC/ABS with 4%SILIPLAS2073 is significantly reduced. As shown in FIG. 3 and FIG. 4, after adding SILIKE Anti-squeaking Masterbatch, the stick-slip state and noise condition of PC/ABS are significantly improved.

By comparing the impact strength of PC/ABS before and after using SILIPLAS2073 (as shown in the figure below), it can be seen that the impact strength is significantly improved after adding 4%SILIPLAS2073.

In summary, the noise reduction effect of SILIKE Anti-squeaking Masterbatch in PC/ABS automotive interior parts is obvious, which can minimize disturbing noise and vibration, improve impact strength and basically do not affect its key performance, and provide a quiet internal environment for car driving. In addition to being suitable for automotive interior parts, it can also be used in building components, home appliances and other fields.
