Case Study - Reducing NVH in Glove Boxes
Background
Minimizing noise is a common challenge automotive engineers face during the design process. Noise, vibration and harshness is often a result of friction between two components. When tasked with reducing friction and NVH, a lubricant is often selected as a cost-effective solution. A supplier of plastic components for major Automotive OEMs approached Nye to recommend a grease for the latch of their new glove box design. This supplier had previously ordered from Nye and was satisfied with their experience. They were looking for a grease that would reduce NVH and extend the life of the glove box.
Challenge
- Can we provide a plastic-compatible lubricant that reduces friction and improves durability?
- Can Nye’s lubricant reduce NVH in the customers glove box design?
Solution
Uniflor™ 8512
A PTFE thickened, medium viscosity, completely fluorinated grease
- Compatible with most plastics and elastomers
- Reduces noise and controls motion
- Provides lifetime lubrication
| Product | Chemistry | Temp Range (°C) | Oil Separation (24 hrs @ 150°C) | Evaporation (24 hrs @ 150°C) |
|---|---|---|---|---|
| UNIFLOR 8512 | PFPE/PTFE | -50 to 225 | 6.8% | 1 % |
Results
After completing in-house validation testing, the customer decided that Uniflor™ 8512 was compatible with the materials of their design and sufficiently reduced NVH. In this case, the Uniflor™ 8512 will improve the durability and extend the life of 600,000 glove boxes annually.
