 Why Butyl Tapes used in Sound and Accoustic Damping? ‘A rubber that absorbs a greater amount of energy is a better damper’, This is the principle of noise, vibration and harshness reduction and cancellation using butyl tapes. Butyl Tapes from CENFUSE are high viscoelastic and it absorbs vibrations, noises, harshness by converting mechanical energy into heat energy in low level. When a vibration in the form of noise, shock, sudden impact (like a jerk in automotive) butyl tape absorbs and converts this into low heat acting as a absorber or an NVH shield. CENFUSE tapes are made from Butyl Rubber, along with high viscosity polybutylene with high extending non toxic fillers which will keep the tape non curing and flexible. Due to its non curing property it stays highly viscous and never hardens or become brittle over time during the change in temperature. The tape is of high density and the same can be increased or decreased under tight lab conditions based on the customer require...

  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...
