GENERAL PURPOSE TUBES

The general purpose tubes and hoses are used for the general purposes which do not require high range of purity of the compound. These are mostly used in many domestic appliances and in the workshops or hobby applications because of their excellent flexibility.

MEDICAL/FOOD GRADE TUBES

These are specially designed hoses and tubes which are made in a manner so that they do not react with any medical or food material. They are sterilized in standard autoclaves in order to make them fit for the application in which they come in close contact with the food ingredients, body tissues and fluids or sensitive drugs. In this particular type of tubing the manufactured silicone tubes and hoses are completely tasteless, odorless, and non-toxic with a special property which does not support bacterial growth.

The high pressure tubes and hoses are made by strengthening their composition with wire or polyester braids which combats expansion and flattening. These tubes are mostly used when then the tubes are in direct contact with pressurized gases or suction is conducted. However, sharp edged clamps and fitting should be avoided near the tubes as they have low tensile strength and resistance to steam which may cause excessive wear and tear.

USES OF SILICONE TUBES IN THE INDUSTRIAL SECTOR

Silicone has a multiple usage in the industrial sector because of its excellent properties and types which provide a very wide area for functioning. Some of these uses are:

Butyl Rubber Sheets, Manufacturer, Exporter, Mumbai, India

Butyl Rubber Sheets

Butyl rubber sheets are also known as isobutyl-isoprene rubber (IIR) in the commercial world. They are manufactured by polymerizing of 98% isobutylene with 2% of isoprene, which is a naturally occurring organic compound produced by many plants. The compound has wide industrial usage due to its remarkable property to retain air and its resistance against any form of deformation due to the extreme heat or weather conditions. These distinguishing features also make it the preferred choice in the automobile industry for inner tube manufacture.

CHARACTERISTICS:

Some of the key characteristics of the PTFE rods are:

The IIR has low moisture permeability due to its closely knit molecular structure.
The same structure is responsible for its excellent resistance against ozone and chemical attack.
The IIR has got excellent ageing stability making it last long without replacement or repair.
It has got very high hysteresis.
It has extremely low levels of saturation.
It can be used in extremely wide range of temperatures lasting from -45C to +130C.
The low resilience of the IIR makes it an ideal material for vibration damping.
It is used with hydrocarbons and oils due to its low resistance.
It does not tear easily.
It is extremely resistant to flexing, abrasion and weathering making it an excellent choice for outdoor usage.
