More About Silopren* LSR 4655 SL Liquid Silicone Rubber

Silopren LSR 4655 SL can be customized by a range of durometers and lubricant load levels – all USP Class VI and ISO 10993 (parts 5, 6, 10 and 11) compliant.  In addition, it can provide a delayed lubricant surface bloom which enables efficient part molding without the common mold fouling seen with other self-lubricating materials.

As evident by a low coefficient of friction, Silopren LSR 4655 SL can provide high-slip surface for the automated assembly of molded components and devices. Molded parts made from Silopren LSR 4655 SL have been shown to have long lubricating life. 

Silopren LSR 4655 SL can also be formulated to a wide variety of hardnesses via our custom compounding center to meet specific end use requirements.  Silopren LSR 4655 SL is an excellent candidate for a variety of applications that require a lubricious surface including seals, stoppers, needle-free access valves, septums and o-rings.
