Silicone rubber is an elastomer composed of silicone together with carbon,oxygen and hydrogen.
IN 1930, JAMES FRANKLIN HYDE RAN THE FIRST RESEARCH TO PRODUCE COMMERCIAL SILICONES.
Silicon is an element which is present in silica (sand) while silicone rubber is manufactured by extracting silicon from silica and passing it through hydrocarbons. It's then mixed with the other chemicals to create silicone.
A silicone or polysiloxane is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group).
Silicone rubber has wide temperature range from -80 to 300°C so this elastomer can be used for wider range of products which will be able to sustain the above given temperatures in various industries.
Transparency Wide Service Temperature Range Resistance to Natural Ageing (Oxidation & UV) High Fire and Flame Resistance Low Temperature Flexibility Hydrophobic in Nature Good Chemical Resistance High Dielectric Strength & Excellent Insuating Properties Excellent Processibility Non-Toxic in Nature Biologically Neutral
The various types of silicone rubbers include room temperature vulcanize, liquid silicone, fluorosilicone and high-consistency rubber.
VMQ(Vinyl Methyl PolySiloxane),PVMQ(Phenyl Vinyl Methyl PolySiloxane),FVMQ(Fluoro Vinyl Methyl Polysiloxane)
There are two types: 1.Platinum Curing , 2.Peroxide Curing
Curing agent is used to vulcanize the raw elastomers at higher temperature by creating crosslinks .
Platinum Cured Silicone has Non-yellowing & Clearer appearance, Good Tensile & Tear Strength compared to Peroxide Cured Silicone and It is preferred by the pharmaceutical, food and beverage industries due to its transparency and lack of peroxide by-products ;On the other hand Peroxide is Cost-effective,Easy to produce & Requires lower temperature to cure,Longer Shelf-life.
Post-curing is the process done on the silicone products after curing which is mandatory so to eliminate odour, stickiness and as well as to obtain optimum properties.200°C @ 4 hours
FLUOROSILICONE ARE MATERIALS MADE OF SILICONE ELASTOMER BASE THAT HAS BEEN FLUORINATED TO PREVENT IT FROM DEGRADING WHEN IT COMES INTO CONTACT WITH CORROSIVE CHEMICALS ,FUELS & HARSH ENVIRONMENTAL CONDITIONS.
MAIN DIFFERANCE IS OF FLAME RESISTANCE AND FLUOROSILICONE HAS BETTER SERVICE LIFE COMPARED TO SILICONE BUT IT IS MORE EXPENSIVE AS COMPARED TO SILICONE.

AN INFLATABLE IS AN OBJECT THAT CAN BE INFLATED WITH A GAS, USUALLY WITH AIR, BUT HYDROGEN, HELIUM AND NITROGEN ARE ALSO USED. ONE OF SEVERAL ADVANTAGES OF AN INFLATABLE IS THAT IT CAN BE STORED IN A SMALL SPACE WHEN NOT INFLATED, SINCE INFLATABLES DEPEND ON THE PRESENCE OF A GAS TO MAINTAIN THEIR SIZE AND SHAPE.

MSDS means Material Safety Data Sheet. A Material Safety Data Sheet (MSDS) is a document that contains information on the potential hazards (health, fire, reactivity and environmental) and how to work safely with the chemical product. It is an essential starting point for the development of a complete health and safety program. It also contains information on the use, storage, handling and emergency procedures all related to the hazards of the material. The MSDS contains much more information about the material than the label. MSDSs are prepared by the supplier or manufacturer of the material. It is intended to tell what the hazards of the product are, how to use the product safely, what to expect if the recommendations are not followed, what to do if accidents occur, how to recognize symptoms of overexposure, and what to do if such incidents occur.
The minimum radius to bend a tube or hose without twisting it is known as Bend radius. It is mainly used for Hoses
Burst pressure is literally the pressure that a pressure vessel like pipe or tube can handle before rupturing or “bursting”. Burst pressure is a function of the material’s strength and pressure vessel dimensions (i.e. wall thickness, inside and outside diameter).

The Viton having a specific gravity of 1.86. Which is greater than the acid solution (sulfuric acid) will sink. All other elastomers which have a specific gravity of less than 1.73 will float,we can also know by it's appearance & smell.
Viton rubber is a fluoro elastomer, whereas epdm rubber is ethylene-propylene-diene-monomer. The primary differences between Viton® and EPDM is in their chemical resistance and temperature ranges.Viton® temperature resistance ranges from -20°C to 210°C, while EPDM temperature resistance ranges from -45°C to 145° This means that both are excellent for extreme temperatures, but EPDM has a slight edge in colder temperatures, while Viton is better for heat resistance at higher temperatures.Viton is resistant to mineral and vegetable oils, gasoline, most alkalis and aromatic hydrocarbons. . EPDM, on the other hand has good resistance to hot water and steam, silicone oils, polar solvents like ketones and alcohol and glycol based brake fluids
Hoses are typically used for applications that involve high pressure, whereas a tube is more often used for lower pressure applications.
C.T. Sleeve is tightly installed on roller by air pressure as its inner dia is less than roller dia.
Systemic Toxicity tests evaluate the generalized biological effects to organs and tissues following exposure to a medical devices, bio-material, or their extracts. The term systemic implies that the exposure occurs by one route and the toxic substance is carried to distant locations causing an adverse effect. Systemic toxicity is typically evaluated in studies of acute, sub-acute, sub-chronic, and chronic duration based on the device’s intended exposure.
