Synthetic lubricants that reduce noise and convey a quality tactile feel to hand-operated interior components, while ensuring material compatibility.

Compartments such as pull-out bins, door compartments, cupholders and the glove box. In most instances, the sliding surfaces of these interior components are exposed when pulled into their open positions. A lubricant that stays in place and gives plastic a quality sound and feel is recommended.

Sun Visor. A visor’s two rotating parts stay at rest for long periods – a difficult duty for grease, which tends to get squeezed out of the surfaces that are in contact. Additionally, due to the visor’s location, lubricants cannot leak oil or emit odour. A odourless, synthetic hydrocarbon grease is recommended, enabling the visor to remain in place for extended periods, yet move smoothly when activated.

Seat lubrication is common; lubricating seat tracks is an aesthetic and mechanical challenge. When seats are pushed completely forward or back, a portion of the tracks is exposed, so neutral coloured greases are preferred. Because of the track’s proximity to seat fabric and carpeting, the grease cannot stain or leak oil. Finally, the seat track assembly has to allow for play without rattling or vibrating at high speeds.

Climate control systems. Contemporary climate control systems rely upon a series of motorised vents to re-route airflow for operator comfort. A synthetic lubricant for this application should be engineered specifically to work with plastic gears and be virtually odour free. It should also offer stability at low temperatures.

Shifter & Gear Levers. PRNDL assemblies require lubrication mainly to dampen noise and create a perception of quality not often found in plastic parts. The synthetic lubricant should enable the mechanism to slide smoothly between notches, while imparting a quality feel to the thumb-activated release mechanism. It should withstand the cold and offer vibration and noise reduction.
