- Wear and Friction Solutions Automotive Interiors
The perception of quality in an automotive interior goes beyond how the interior looks and includes how it “feels” and how it “sounds”. Buttons and knobs must not stick and should move smoothly. There should be no harsh or unwanted noise to take away from the driving experience. LUBRICOMP™ and LUBRILOY™ compounds can help contribute to the high quality interior consumers demand.
Buzz, Squeak and Rattle
The panels and trim pieces that make up the structure of the vehicles interior are prone to noise generation whenever two parts come in contact with each other. BSR is one of the primary quality issues facing automotive manufactures today. Traditional solutions include adding tape based felt spacers to keep material separated, adding cost and complexity to the build.
Internally Lubricated Compounds:
The addition of an internal lubricant to a thermoplastic material can help reduce the coefficient of friction between two plastic parts, allowing them to slide past each other reducing the vibration that leads to noise. Traditional lubricants like silicone and PTFE are effective, and novel alloy technology can add improved damping characteristic.
Measuring Performance
Standard wear and friction measurements like thrust washer wear (ASTM D3702) or sliding sled (ASTM 1894) testers can’t always determine if two mating materials will generate noise. Specialized testing for slipstick characteristics (VDA 230-206) can be a more effective tool for comparison. The wear and friction labs at LNP can leverage multiple characterization tools to aid in application development efforts.

- ᵍ Measurements made from Laboratory test Coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article.
- ⁷ Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding.
