- Chemistry. Typically, lubricants based on silicone, PFAE (perflourinated), most synthetic hydrocarbons (SHC or PAO), or mineral oils work well with plastics.
- Viscosity/NLGI grade. High-viscosity oils, generally ISO VG 100 or more, are less apt to penetrate and adversely affect plastic materials.
- Aging resistance. As lubricants age, they are more likely to attack plastic. Therefore, long-term plastic applications call for synthetic lubricants, which have a high aging resistance.
- Recommendations. Mineral-oil-based lubricants don’t attack most plastic materials and offer excellent performance for the dollar in general plastics applications.
What lubricants can be used on plastics?

Synthetic HydroCarbon (SHC)-60 to 150°C Ester -70 to 150°C PolyAlkylene Glycol (PAG) -40 to 180°C Silicone -75 to 200°C PerFluoroPolyEther (PFPE) -90 to 250°C. Make sure your oil and plastic are compatible, otherwise the part may crack or craze, leading to premature failure. Use caution with ester and polyalkylene glycol.
Why use synthetic lubricants in long-term plastic applications?
Feb 01, 2019 · Montan Waxes are great to use with engineering plastics like PVC, polyester, polyamide, etc. Montan Waxes offer high effectiveness even at low concentration levels. There is no product loss and it is non-blooming. Polyolefin Waxes are used as an external lubricant with PVC. They provide great lubrication as well as aesthetic appearance, which is especially …
What is the best lubricant for hard plastic?
siliconeLubricants with silicone or PTFE (polytetrafluoroethylene) are best for use on plastic surfaces. PTFE is hydrophobic, meaning it repels water, so lubricants containing it are effective in damp conditions. Silicone lubricants make surfaces ultra-slippery while repelling water.Sep 27, 2013
Is vaseline a good lubricant for plastic?
Yes- vaseline is a petroleum jelly and it can degrade plastics - AND - it is about 8000 weight! It will glue the gears rather than lube them. I suggest some white lithium grease - and just a touch will do ya. Candle wax works very well too.Dec 14, 2015
Can WD 40 be used on plastic?
WD-40 can be used on just about everything. It is safe for metal, rubber, wood and plastic. WD-40 can be applied to painted metal surfaces without harming the paint. Polycarbonate and clear polystyrene plastic are among the few surfaces on which to avoid using a petroleum-based product like WD-40.

Will lithium grease harm plastic?
Lithium-based lubricants are used in cars and machinery in general. It's not advisable to use them on plastic parts. As lithium is based on petroleum, it tends to speed up rubber and plastic components decay.Apr 19, 2021
Will silicone spray hurt plastic?
No, silicone sprays won't damage plastic. They actually work very well to lubricate and protect plastic surfaces.Dec 2, 2020
Is silicone lubricant good for plastic?
Because silicone oil is super slippery and minimally-reactive, it can lubricate most anything. It works especially well on porous items, such as plastic parts, but is a good lubricant on locks, hinges, and guns.
How do you rejuvenate plastic?

What is the best lubricant for plastic gears?
Typically, lubricants based on silicone, PFAE (perflourinated), most synthetic hydrocarbons (SHC or PAO), or mineral oils work well with plastics.Aug 1, 2000
Can you lubricate plastic?
A lubricant's compatibility with plastic is largely determined by its chemical structure. Lubricants based on silicone, perfluorinated PFAE, mineral oils, and synthetic hydrocarbons (SHC or PAO), typically work well with plastics.
What is self lubricating plastic?
Self-lubricating plastics from igus® are made from tribologically-optimized polymer blends. Tribology is an area of study that deals with the design, friction, wear and lubrication of interacting surfaces in relative motion.
Is dielectric grease safe for plastic?
Since dielectric grease is a silicone grease, it should not be used on silicone-based rubbers or plastics, as it will break them down over time. The grease does not conduct electricity, so it shouldn't be applied directly to the mating surfaces (pins and sockets) of an electrical connection.Feb 26, 2015
What are the two types of lubricants used in plastics?
There are two types of lubricants that are used with plastics, external lubricants and internal lubricants. External lubricants are generally fatty amides, paraffins, etc.
Why use synthetic lubricant in plastic?
Hence, it is ideal to use synthetic lubricants in longer-term plastic applications because synthetic lubricants tend to have high aging resistance. Formaldehyde and styrene, which are outgassing plastic byproducts accelerate the lubricant aging process and hence must be kept to a minimum if possible.
What is polyolefin wax used for?
Polyolefin waxes are also used as internal lubricants in PO compounds and masterbatch applications.
What additives are not recommended for use with plastic?
Metal part lubricants containing EP additives, corrosion protector, and metal deactivator additives are not recommended for use with plastics. Viscosity – High viscosity lubricants with ISO VG greater ...
What temperature can Montan wax be used in?
They have great compatibility with plastic and can operate in a wide temperature range of -90F to 425F. Montan Waxes are great to use with engineering plastics like PVC, polyester, polyamide, etc. Montan Waxes offer high effectiveness even at low concentration levels. There is no product loss and it is non-blooming.
Why do 3D insiders use lubricants?
Lubricants are used in plastics mainly to reduce friction between the processing machinery and the plastic materials. Another reason which may not be apparent is the reduction of friction between the molecules of the plastic materials.
Why should the melting point of lubricant be close to the molding temperature?
The melting point of the lubricant should be close to the molding temperature because that will allow the formation of liquid films on the plastic surface when the plastic shape has formed. Too much difference in those temperatures can cause complications.
