Anti-Squeaking Masterbatch, dampen sound, diminish noise, PC / ABS parts, reduce Evs’ interior noises,

Description

Noise reduction is an urgent issue in the automotive industry. The noise, vibration and sound vibration (NVH) inside the cockpit is more prominent in ultra-quiet electric vehicles. We hope that the cabin becomes a paradise for leisure and entertainment. Self-driving cars need a quiet internal environment.

Many components used in car dashboards, center consoles and trim strips are made of polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) alloy. When two parts move relatively to each other (stick-slip effect), friction and vibration will cause these materials to produce noise. Traditional noise solutions include the secondary application of felt, paint or lubricant, and special noise-reducing resins. The first option is multi-process, low efficiency and anti-noise instability, while the second option is very expensive.

Silike’s anti-squaking masterbatch are a special polysiloxane that provides excellent permanent anti-squeaking performance for PC / ABS parts at a lower cost. Since the anti-squeaking particles are incorporated during the mixing or injection molding process, there is no need for post-processing steps that slow down the production speed. It is important that SILIPLAS 2070 masterbatch maintain the mechanical properties of PC/ABS alloy-including its typical impact resistance. By expanding design freedom, this novel technology can benefit automotive OEMs and all walks of life. In the past, due to post-processing, complex part design became difficult or impossible to achieve complete post-processing coverage. In contrast, silicone additives do not need to modify the design to optimize their anti-squeaking performance. Silike’s SILIPLAS 2070 is the first product in the new series of anti-noise silicone additives, which may be suitable for automobiles, transportation, consumer, construction and home appliances.

Features

•Excellent noise reduction performance: RPN<3 (according to VDA 230-206)

• Reduce stick-slip

• Instant, long-lasting noise reduction characteristics

• Low coefficient of friction (COF)

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

• Effective performance with low addition amount (4wt%)

• Easy to handle, free flowing particles

The noise risk priority index (RPN) results show that when the content of SILIPLAS 2070 is 4% (wt),the RPN is 2. RPN below 3 indicates that the noise is eliminated and there is no long-term application risk.

Fundamental Parameters

The graph of the pulse value change in the stick-slip test of PC/ABS after adding 4% SILIPLAS2070:

It can be seen that the stick-slip test pulse value of PC/ABS after adding 4% SILIPLAS2070 has dropped significantly, and the test conditions are V=1mm/s, F=10N.

After adding 4% SILIPLAS2070, the impact strength will not be affected.

Benefits

• Minimize disturbing noise and vibration

• Provide stable COF during the service life of parts

• Optimize design freedom by implementing complex geometric shapes

• Simplify production by avoiding secondary operations

• Low dosage, improve cost control

Application field

• Automotive interior parts (trim, dashboard, console)

• Electrical parts (refrigerator tray) and trash can, washing machine, dishwasher)

• Building components (window frames),etc.

Goal customers

PC/ABS compounding plant and part forming plant

Usage and dosage

Added when the PC/ABS alloy is made, or after the PC/ABS alloy is made, and then melt-extrusion granulated, or it can be added directly and injection molded (under the premise of ensuring dispersion).

The recommended addition amount is 3-8%, the specific addition amount is obtained according to the experiment

Package
