This plastic‑friendly synthetic hydrocarbon lithium grease is a lithium‑soap thickened lubricant based on synthetic hydrocarbon base oil. It is specially developed to minimize stress‑cracking risk on engineering plastics. The grease provides boundary lubrication for meshing plastic gears and moving automotive plastic components, reduces friction and abrasion during cyclic movement, and maintains long‑term component integrity in automotive interior mechanical assemblies.
Product DetailsPlastic‑Friendly Grease Synthetic Hydrocarbon Lithium, Compatible with Plastic for Gear Automotive Plastic ComponentThis synthetic hydrocarbon lithium grease is compounded using refined synthetic hydrocarbon base fluid, lithium soap thickener and balanced anti‑wear, anti‑oxidant additives. The base‑oil composition is carefully selected to eliminate aggressive aromatic fractions that commonly induce environmental‑stress cracking of polycarbonate, ABS, POM and other engineering plastic grades.
When applied onto meshing plastic gear tooth surfaces, the grease forms a tenacious lubricating film. This film lowers sliding and rolling friction between gear teeth, mitigates tooth‑surface abrasion, reduces gear‑generated noise, and extends the service life of plastic gear sets. For movable automotive plastic components including adjustment sliders, latch mechanisms and interior actuating parts, the grease lubricates mating plastic‑to‑plastic and plastic‑to‑metal contact interfaces. It alleviates stick‑slip movement and suppresses squeaking noise during repeated mechanical actuation.
It exhibits outstanding material compatibility with a broad portfolio of automotive engineering plastics. It will not promote swelling, softening, crazing or stress cracking on plastic parts even under sustained static contact. Meanwhile, the incorporated anti‑oxidant additives resist thermal‑oxidative deterioration when components are exposed to moderate interior temperature fluctuations inside vehicle cabins.
The grease is suitable for initial lubrication during automotive component mass‑production assembly, as well as maintenance lubrication of plastic gear mechanisms. Appropriate coating thickness should be controlled; excessive grease quantity may attract dust and particulate contamination, which accelerates abrasive wear on delicate plastic gear surfaces.
Blending with silicone‑based greases or mineral‑oil lithium greases is not recommended. Incompatible mixtures may impair the plastic‑friendly properties and weaken anti‑wear performance. Store the product in tightly sealed containers within cool, dry indoor warehouse. Avoid prolonged high‑temperature storage to preserve original grease consistency and reliable plastic compatibility for automotive plastic gear and component applications.
