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:

Nitrile Rubber Sheets, Manufacturer, Exporter, Mumbai, India

Nitrile rubber Sheets

rubber belongs to the family of unsaturated copolymers and is also commonly known as Buna-N, Perbunan, acrylonitrile Butadiene rubber and NBR.

PROPERTIES :

The NBR sheets have an excellent resistance towards abrasion and gas diffusion.
NBR sheets have great affinity towards a wide variety of surfaces due to the polarity of the Nitrile Rubber Molecules which makes it an excellent adhesive for the industrial sector.
It can work under high operating temperature ranging from -30C to +120 C.
The NBR sheets show rapid depletion if exposed to direct sunlight or moderate to high atmospheric ozone.
The NBR sheets were primarily designed to prevent oil attack due to its excellent mechanical properties which remain intact even when it is directly exposed to oil and grease for a prolonged period.

USES

The Automobile and Industrial sector has multiple requirements and usage of NBR as it is used in the production of variety of goods:

It is used in making of disposable Non-Latex Gloves
Automotive transmission belts
Hoses
O-rings
Gaskets
Oil seats
V belts
Synthetic leather
Printer’s form rollers
Cable jackets

In the chemical industry the NBR has a role to play as it is used in the manufacture of:

NBR latex is used in the preparation of adhesives
Manufacture of pigment binders
