Rubber Moulded Goods & Extrusions

Manufacturing Rubber and its components is like cooking a recipe. The better ingredients you use and the purity of the same has a telling effect on the finished product. Cooking is an art so the skill of labour and presence of updated technology is important to ensure homogeneous curing of rubber to ensure the products do not malfunction when working in different environments.

Infrastructure and Quality Control

Process control can only be achieved when all aspects of production is done in-house.

At our manufacturing facility in Kolkata, we start from inbound material analysis and branch out to compounding, mixing, extrusion, moulding and finishing inhouse.

All our dies are made in-house on VMC & CNC with complete 3D software support in Solidworks and Most2D

It's important to know which physical, mechanical and chemical resistance properties are required. It's also important that a material is compounded and tested to meet any necessary industrial specifications such as UL, ASTM, IS, BS, SAE, FDA, NSF International Standards. Listed.

We have all the in-house facilities to check various physical attributes and have a experienced team to help recommends the best rubber for your use and application.

We check and select our rubbers based on :

Tensile strength

Elongation @ Break

Hardness range / Durometer

Compression set at room and operating temperatures

Aging in sunlight, ozone, heat, storage, etc.

Colour (if colour matching is desired or necessary

Aesthetics:

Speed of recovery from deflection

Flexibility

Permeability to gases

Resistance Properties:

Reaction to acids or caustics

Reaction to Oils

Hydrocarbon solvents

Oxygenated solvents

Flame or temperature extremes

Tearing

Abrasion

We work with all kinds of rubber. Brief synopses of various types of rubber we work with are:

Silicone (Polysiloxane)

features excellent resistance to ozone, sunlight and oxidation, and is very colour stable. It also maintains excellent flexibility at low temperatures, has outstanding resistance to high heat, has low compression set and is a very good electrical insulator. However, it is not recommended for applications that require abrasion resistance, tear and cut growth resistance and high tensile strength. Nor is it recommended for resistance to oil, gasoline, solvents, alkalis and acids.

EPDM (Ethylene-Propylene-Diene-Monomer)

EPDM (Ethylene-Propylene-Diene-Monomer) is well known for its excellent ozone, weathering and aging resistance. It also has excellent water and steam resistance, maintains its flexibility at low temperatures, features excellent resistance to alkalis, acids and oxygenated solvents. It is not recommended for resistance to oil, gasoline and hydrocarbon solvents. EPDM is found in a wide range of applications and is excellent for outdoor use.

Nitrile (Acrylonitrile-butadiene)

Nitrile (Acrylonitrile-butadiene) has very good oil, gasoline and abrasion resistance. Its resistance to alkalis and acids increases as the nitrile content of the compound increases. Nitrile must be specially compounded for resistance to ozone, sunlight and natural aging. It has poor resistance to oxygenated solvents. Nitrile is superior to neoprene in oil and solvent resistance, but is not recommended for applications where it is exposed to severe weathering.

Viton (Fluoroelastomer)

Viton (Fluoroelastomer) provides premium performance and long-term reliability in very harsh and corrosive environments. Their exceptional resistance to heat aging and a broad range of fuels, solvents and chemicals makes them ideal for many demanding aerospace, automotive and industrial applications. Fluoroelastomers also offer excellent resistance to weather, ozone, oxygen and sunlight, and are inherently more flame retardant than hydrocarbon rubbers.

SBR (Styrene-Butadiene-Rubber)

SBR (Styrene-Butadiene-Rubber) has excellent impact strength, good resilience, tensile strength, abrasion resistance and maintains flexibility at lower temperatures. It is not the elastomer of choice where resistance to oil, gasoline and hydrocarbon solvents is required. SBR materials are also not suitable for exposure to the outside elements such as UV and ozone

SBR (Styrene-Butadiene-Rubber)

SBR (Styrene-Butadiene-Rubber) has excellent impact strength, good resilience, tensile strength, abrasion resistance and maintains flexibility at lower temperatures. It is not the elastomer of choice where resistance to oil, gasoline and hydrocarbon solvents is required. SBR materials are also not suitable for exposure to the outside elements such as UV and ozone

Natural Rubber (Polyisoprene)

Natural Rubber (Polyisoprene) as the name suggests is the only naturally occurring elastomer. It has excellent impact strength, resilience, tensile strength, abrasion resistance and tear resistance. It is not recommended for applications where resistance to oil, gasoline and hydrocarbon solvents is required.

Based on the above products we manfacture all kinds of extrusions in different shapes , sizes and material.

We take pride in making rubber gaskets suitable to carry Portable water and peroxide cure it to pass strict NFS guidelines.

Our state of the moulding unit is capable to mould various complex shapes with steel or plastic cores and work on zero tolerances to allow complex industrial sealing applications at both high and low pressure.

Some of our standard products include gaskets, Rubber Pads, Seals, Tubings, Flange Gaskets, Washers, Sponge Gaskets, Silicon Rubber Tops, Gaskets for uPVC windows. Our extrusions find application in various automobile applications.
