Why Silicone Rubber is a Gold standard in Industry where you need a better service life ?

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 degradation to certain corrosive chemicals. The base metal from both are derived are Sand or Silica and then processed accordingly. We can compare it as a flexible glass in polymers owing to its resemblance due to the base metals, properties it possess.

Bond Energy of glass 450 to 460 kJ/mol, Silicone rubber 440 to 450 kJ/mol

and the list goes on with your imagination and requirements. Silicone rubber proves to be a polymer which can be fabricated into any extend with the proper ingredients and fillers based on its mysterious chemistry and nature. This list will be kept on updating and each properties will be deeply technically explained.

Silicone are again classified based on its type of curing

Processing methods like Extrusion, Moulding, Hand Fabricating, Dipping, Calendaring etc.

All types of Industry Standards, Compliances and Specifications have been Covered

FDA, USP Class VI, ISO 10993, BfR
