Characteristics:
●Within a certain period of time, the surface of products can precipitate silicone oil for self-lubricating.
●Excellent heat aging resistance and low compression set performance, oil content 5%~8%.
Main Applications:
●Automotive industry, machinery industry, and aerospace industry, such as various silicone rubber connectors, sealing elements and washers requiring self-lubricating property with molding process.

● Physical data in the above table is for reference only.
● Vulcanization condition: 175℃* 5Min.
● Ratio of curing agent liquid 2,5-Dimethyl-2,5-di(tert-butylperoxy) hexane: 0.65%.
●The supplied test report is obtained by the Quality Inspection Department with the curing conditions and testing method of the company; due to the difference of curing conditions and testing method, we can’t guarantee that both parties obtain the same testing result, and we suggest that users should use the test data obtained under their own testing conditions as the reference for service performance. All the above performance data and application recommendations are only a reference for use on the service performance of product, instead of a guarantee on the effectiveness or general applicability of our products under a certain application.
