Neoprene

(CR….Chloroprene Rubber) General Temperature Range -10/+220 F

Generally resistant to: Moderate acids and chemicals, ozone, oils, fats, and many solvents.

Generally affected or attacked by: Oxidizing acids, esters, and ketones. Aromatic chlorinated and nitro hydrocarbons.

This material can be found in everyday products which you may use. This synthetic rubber is rather flexible over a wide temperature range. Neoprene is used in diving suits because of its water resistant characteristic. This enables the material to be used in electrical insulation, automotive fan belts, orthopedic braces, protective sleeves, etc. This material can also be used as a noise insulation for various products such as drum practice pads. Weather stripping is typically made out of neoprene because of its fire resistant characteristics.

Neoprene is a good general purpose material for many gasket applications.

Natural Rubber

(NR….Polyisoprene) General Temperature Range -20/+185 F

Generally resistant to: Water, air and average concentration acids. Bases, alcohols, salts, ketones, and has the best abrasion resistance.

Generally affected or attacked by: Strong acids, ozone, bases, oils, solvents, and most hydrocarbons.

This material is typically collected in the form of latex from specific trees. Once the milky substance is refined, the rubber is ready for commercial use. Natural rubber has a large stretch ratio and resilience which can be useful when needed. This extremely waterproof material is used for many products you may use on a daily bases such as the shoes you wear.

Natural Rubber, also known as “GUM” rubber has good tensile strength and tear resistance.

Applications

Because of its elasticity and resilience, natural rubber is used in many different applications. We create natural rubber gaskets and natural rubber washers. Rubber makes a great seal because it is resistant to water and many other fluids. Natural rubber gaskets, for instance, do an excellent job of sealing up a small space between two components and preventing any leaks during operation. In combustion engines, natural rubber gaskets can help to maintain the compression that is essential to create power. Other applications include:

Quality Assurance

Our extensive knowledge in rubber manufacturing makes us an excellent choice if you are in need of a natural rubber gasket manufacturer or a natural rubber washer manufacturer. With capabilities like extrusion, molding and die cutting all in our state of the art facility, there’s very little that we can’t do in terms of rubber manufacturing. works very closely with all of our material suppliers so that we can control the quality of our products and always meet the needs of customers by having the right quantities on hand at all times.

Other Materials

As great as natural rubber may be, it is by no means the only product that we work with.

Closed Cell Sponge

Produce closed cell sponge products to your specifications. This material is used for gasket and sealing applications that require a soft, compressible material. These sponges are extremely impermeable to water, and good choices for shock absorption, weather sealing and thermal barriers. A wide range of closed cell sponge materials are available to best suite your applications. From 100% pure materials such as Neoprene or EPDM, to high quality blended materials such as Neoprene/EPDM/SBR mixes. Many materials meet UL-94 requirements and can range in temperature from -110 to +220 F. Many of these also meet FMVSS-302 requirements.

We work with a large variety of non-metallic materials, one of these materials is the soft, compressible material known as closed cell sponge. This type of rubber has both a wide range in terms of temperature environment, from extreme cold to intense heat. Another name for closed cell sponge is expanded rubber; it gets this name due to how the material is made up. The cells are similar to that of balloons, the cells in a closed cell sponge hold gas which does not allow for moisture to pass through the material.

If you are unsure if closed cell sponge is the right material for your application, do not hesitate to call one of our knowledgeable experts today. We would be happy to discuss our materials in detail, going over every advantage and disadvantage each material brings to your application.

Viton

(Fluorocarbon….Fluorinated Hydrocarbon) General Temperature Range +10/+450 F

Generally resistant to: All aromatic, aliphatic, and halogenated hydrocarbons. Also many acids, animal and vegetable oils.

Generally affected or attacked by: Ketones, esters, and nitro containing compounds.

This synthetic rubber is relatively popular for the production of O-rings and molded parts. It can also be used in linings of hose for automotive when biodiesel is used. This material should not be used in areas where high temperatures exist due to the decomposition and leaking of fluids from specific compounds.

Viton is known for its higher temperature resistance along with the ability to withstand many solvents, acids, fuels, and oils.
