PST-434 is a silicone grease that’s designed for demanding applications where maximum surface contact is required under load, and where extremely low temperatures are expected. This Lithium-filled silicone grease is comparable to Dow Corning Molykote 33 bearing grease (DC-33) from Dow Corning, and Novagard G321 silicone lubricant.
PST-434 has an operating range of −70°C to 204°C and an unworked penetration in the 240 to 300 range with a typical value of 260. This silicone lubricating grease provides the following features:
In addition, PST-434 silicone lubricant combines hydrolytic stability with chemical and thermal resistance.
Applications for PST-434 silicone grease include:
PST-434 is supplied in drums, plastic pails, jars, cartridges, and plastic tubes. Private labeling and custom packaging are available to meet special requirements. Contact PolySi Technologies for more information.
