Nitrile rubber (NBR)

The majority felt the proposed applications, oil and grease resistant, general purpose equipment. For fuel and industrial fluids contain various mixtures. Gilikol based brake fluids and EP additive is weak resistance to oils. Nitrile rubber, typically at temperatures between -40 ° C to 105 ° C is used, spaced 120 ° C is stable. Value functions are preferred in terms of balance.

Production of gaskets, cork-filled nitrile compounds are used.Strength properties of these materials such as nitrile is standard.The presence of yeast also compressibility (volume to shrink) feature saves. Nitrile mushroom, but use a static field to find applications.

Polyacrylic rubber (ACM)

EP additives in oils at high temperatures and is more durable than nitrile rubber150 ° C is usually used. Ozone resistance is good. Fuel resistance and low temperature resistance is low (-30 ° C min.) Gear box seals are used in particular.

Silicone Rubber (MQ, VMQ, PVMQ)

-60 ° C to 200 ° C between uses.Spaced at 250 ° C is stable.The main application areas are the crankshaft seals. Flexibility, weather resistance and ozone resistance is high. Fuel, the EP type lubricants and is not recommended for applications requiring high mechanical properties.

Fluorocarbon Rubber (FKM)

-40 ° C to 150 ° C is available. Phosphate ester fluids, glycol based brake fluids, water vapor, ozone and weather resistance is good. For fuel and petroleum-based oils are not suitable.

Styrene butadiene rubber (SBR)

Glycol based brake fluids, acids and bases, is resistant to alcohol. -50 ° C to 100 ° C. These materials are used. Is not resistant to oils and petroleum-based fuels.

Natural rubber (NR)

A temperature range of -60 ° C to 90 ° C.. Environment in terms of strength shows similar characteristics with SBR. Areas that require high flexibility and mechanical properties are used.

Polytetrafluoroethylene (PTFE)

Almost all chemical substances used in industry is a durable plastic material.-260 ° C and 260 ° C are among the areas.Solid with low coefficient of friction. Does not indicate that adhesion-lubricated bearings material. Some types are very good electrical insulator. Depending on the application of pure, glass fiber, carbon, graphite, bronze with PTFE is molybdenum sulfide.

Polyamide (PA)

Common as "nylon" is known. -20 ° C to 90 ° C is available. Limit the use of special types can be up to 140 ° C. Friction and wear characteristics are very good. Oils, fuels, with esters, ketones are resistant.

Hydrogenated Nitrile Rubber (HNBR)

Hydrogenated nitrile rubber polymers derived from NBR. Prepared in this way the properties of materials with high mechanical strength and corrosion that are more resistant.. Media resistance is as NBR.

Thermoplastic polyurethane (TPU)

TPU injection molding business with opportunities for an effective way has good mechanical properties. The main advantage of TPU abrasion resistance over a wide temperature range, flexibility, oils, greases, and is resistant to many solvents.
