Silicone Grease & Silicone Compounds

Silicone Grease & Silicone Compounds PolySi® G-MAN® Lubricants

Silicone Grease and Silicone Compounds from PolySi® G-MAN® Lubricants offer excellent dielectric properties, extremely high and low-temperature capabilities (-100-400 F), water resiliency, and oxidation resistance.

These characteristics make our PolySi® G-MAN® Silicone Greases excellent for lubricating, coating, and sealing plastic and rubber parts. The silicone-based materials reduce friction and provide long-lasting lubrication not found in traditional lubricating materials. PolySi® G-MAN® Silicone Greases are also organic and non-hazardous.

PST-500 Silicone Grease

Silicone compounds by PolySi® G-MAN® Lubricants are grease-like lubricants containing silicone fluids and inert silica fillers.  Silicone compounds are resistant to oxidation and thermal degradation and maintain their properties over a wide temperature range. The PST-500 Silicone Compound Series is designed as release agents, and may be used as o-ring assembly lubricants, non-conductors of electricity, non-curing sealants and as assembly lubricants for plastic and rubber parts. PST Silicone 500 series compounds may be used for applications where they function in a dual role as both a lubricant and a non-curing sealant.

PolySi® G-MAN® Silicone Greases that meet FDA 21 CFR 178.3570 and FDA 21 CFR 173.500 lubricants and incidental food contact include: PST-511, PST-599, PST-504.

If your needs are not met within our standard PolySi® G-MAN® offering, our design engineers can custom blend a lubricant to solve even the most complex lubrication problems. The PolySi® technical team will work with you to identify the best product for your application.
