Overview
  • Platinum Silicone Gaskets

    To make Silicone gaskets, there are two cure system options with silicones, however, that produce materials with different characteristics,whose impact should be considered before selection. Silicone materials may be cured using free radical (peroxide) or addition (platinum) cure mechanisms.

    Platinum-cured and peroxide-cured silicone gaskets can both be made to USP Class VI and other industry specifications, but a platinum-cured gasket has a higher purity and lower leachability than peroxide-cured silicone.


Standards
We provide sanitary gaskets in all standards such as:
★ DIN32676 (Series A)
★ ISO1127 (DIN32676 Series B)
★ ASME BPE (DIN32676 Series C)
★ ASME BPE Category I & II ( lipped & unlipped)
★ ISO2852
★ SMS3019
★ BS4285
★ and etc.

Silicone is widely used in pharmaceutical applications for two major reasons.

First, and foremost
Is safety. Silicone does not contain plasticizers or other additives that could leach into a drug product and cause toxicological issues.

Second
Silicone is highly flexible and tear-resistant, making it a good choice for sealing fluids in downstream processes.


Platinum Cured Silicone VS Peroxide Cured Silicone
Peroxide-cured gaskets contain a small residue of 2,4 DCBA (dichlorobenzoic acid) as a by-product of the curing reaction.
Platinum-cured gaskets have no 2,4 DCBA residues, its only by-product is H2O.
In some critical bioprocesses, the small amount of DCBA might harm the media that is made. The relative value and impact of these characteristics should be evaluated carefully when selecting the silicone type for fluid handling applications.
