  Silicone Curing: Types, What to Choose according to your Industry? In Silicone Rubbe r chemistry majorly 5 types of curing happen Addition Curing using Platinum Catalyst Free Radical Curing using peroxide Condensation Curing using Tin like Catalyst Moisture Curing using Acetoxy, Alkoxy etc. UV Curing using UV Light In this article we will explain the benefits of each curing system and how it helps on selecting the product for different applications. Our Major Focus area will be Platinum based , Peroxide based Curing which is majorly used in the fabrication of silicone rubber. Platinum catalyst based curing is chemical reaction used by Hydrosilylation where vinyl groups in the rubber and silane hydrides react in presence of platinum catalyst to do cross linking. Si–H + CH₂=CH–Si —Pt→ Si–CH₂–CH₂–Si The hydride molecule will connect many vinyl-silicone chains in the presence of platinum, causing an addition reaction, the major factors contribute the reaction is the hydride, v...

This article covers all the features of Silicone Rubber which makes us helps, to understand why silicone chosen over as a best solution for silicone tubes in various industries. All the different properties have been explained scientifically and why it is chosen over different purpose has been clearly mentioned over, the technical data will be updated over periodically and separate technical sheets have been linked for a complete identification. For a better understanding and simplification of the inside chemicals we can compare silicone and glass, both are like relatives with Silica as a common ingredient Molecular structure of glass is Rigid 3 D structure with oxygen linked all sides making it hard with a very high bond energy, whereas silicone is a 2 D flexible organic group with organic( C and H) in the sides making it flexible . This itself explains the non-reactive nature of glass whereas the reactive vulnerability of silicone after a certain temperature and chemical degr...
