Neoprene (Chloroprene) Rubber O-Rings & Seals (3)

Description

NBR (Nitrile) is the most cost effective and commonly available O-ring material. Ideal for use as seals for pumps, drive belts, and other general engineering applications in the hydraulic and pneumatic industry.NBR is good for applications where the O-ring is exposed to fats, greases and animal or vegetable oils.

For applications requiring contact with diesel or temperatures higher than 120°C you may wish to consider Polymax FKM (Viton®) O-rings.

Neoprene (Chloroprene) Rubber O-Rings & Seals (6)

(Video) O RING RUBBER ROUND CORD NEOPRENE SIZE=DIA 10MM

Description

Silicone (VMQ) rubber contains methyl and vinyl groups attached to the main silicone chain. Silicone O-rings are characterised by excellent resistance to temperature extremes and thermal cycling. Silicone rubber compound does not impart odour or taste, which makes it suitable for many food and pharmaceutical applications.

Silicone rubber however, has poor mechanical properties as compared to other elastomers and for this reason silicone O-rings are generally not used in dynamic applications. It is not suitable for use with silicone O-ring lubrication, PTFE alternatives should be used instead.


Temperature Range

  • Up to 200°C (Intermittant)
  • Down to -40°C
  • Recommended temperature range -20°C to +180°C

    Chemical resistance

    • Dry heat
    • High - aniline point oils
    • Chlorinated DI - phenyls
    • Food processing applications
    • Excellent ozone resistance.
    • Water (Low temperature only)

    Not compatible with:
    • Most Petroleum fluids

Neoprene (Chloroprene) Rubber O-Rings & Seals (7)

Description

PTFE is a highly resilient O-ring material unaffected by virtually all known acids, alkalis and solvents. It is tough, abrasion resistant and capable of withstanding temperatures between -200°C to +250°C. It also possesses outstanding weather, ozone and electrical resistance. For this reason, it is the O-ring of choice for use in aerospace, food, pharmaceuticals and telecommunications industries.

PTFE O-rings could be a more economical alternative to FFKM materials, but they are not easily compressed and have little memory to be able to return to their original form. This can be a disadvantage if under permanent strain and may not create the best lasting seal.

Temperature Range

  • Up to 250°C (Intermittant)
  • Down to -70°C
  • Recommended temperature range -60°C to +230°C

    Chemical resistance

    • Excellent resistance to almost all chemicals
    • Not subject to ageing, so a near infinite shelf / storage life
    • Can be use in food, chemical and medical industries (among others)
    • Low elasticity (memory), making it unsuitable for dynamic applications unless energised by suitable material (I.E. rubber)
    • Low coefficient of friction

    Not compatible with:
    • Low compression vacuum sealing flanges
    • High vacuum seals
    • High temperature steam

Neoprene (Chloroprene) Rubber O-Rings & Seals (8)

Description

Chloroprene (or Neoprene / CR) was one of the first developed synthetic compounds, invented by DuPoint™ scientists in 1930. Chloroprene is a good multi-purpose material, it exhibits fair oil resistance and good ozone and weather resistance. A combination of both these properties is usually not found in other commonly available elastomers like NBR and EDPM.

Chloroprene is often used in refrigeration systems due to the excellent resistance to refrigerants such as Freon® (R12, R13, R21, R22, R113, R114, R115, R134A) and ammonia.

Temperature Range

  • Up to 110°C (Intermittant)
  • Down to -40°C
  • Recommended temperature range -30°C to +100°C

    Chemical resistance

    • Ammonia gas
    • High Aniline point oils
    • Refrigerants (Freons)
    • Silicate esters
    • Weather and Ozone

    Not compatible with:
    • Brake fluids
    • Ketones
    • Phosphate esters

FAQs

What is neoprene chloroprene rubber used for? ›

On its own, neoprene is commonly used to mass-produce reliable gaskets, cable jackets, tubing, Orings, seals, tire-sidewalls, gasoline hoses, wetsuits, and orthopaedic braces.

What are neoprene O-rings used for? ›

Neoprene o-rings are typically seen in the refrigeration sector, as they demonstrate remarkable resistance to chemicals such as ammonia and a variety of coolants. Neoprene o-rings also perform well in contact with oils and many chemicals and has good resistance to sun, ozone and weather.

What is the difference between neoprene and chloroprene rubber? ›

Neoprene and chloroprene are types of synthetic rubber materials. Neoprene is a polymer made from chloroprene. The key difference between neoprene and chloroprene is that neoprene is a polymer material, whereas chloroprene is the monomer for neoprene production.

Is neoprene rubber better than rubber? ›

While both materials are durable, neoprene is much more efficient for sealing applications. Its flex cracking resistance and high resilience makes it the superior option for rubber gaskets. Neoprene will withstand highly abrasive conditions much longer than natural rubber and many other materials.

Does neoprene rubber absorb water? ›

Neoprene is a synthetic rubber material that is soft and comfortable to wear, is flexible and is perfect for insulation, it doesn't absorb water. Neoprene is resistant to water penetration, is strong, is quick-drying and is hypo-allergenic.

What does neoprene protect against? ›

Neoprene's chemical inertness helps it resist impacts from weather, ozone and other outdoor variables, as well as withstand petroleum-based mixtures such as solvents, oils and greases. Neoprene bearing pads are also used in bridges as a safety mechanism.

What is so special about neoprene? ›

Neoprene has good resistance to chemicals, water, heat, flames, oxygen and ozone. It has more resistance against water, solvents and heat compared with natural rubber. The material is also good against weather and sunlight meaning that it ages well and does not need replacing too often.

What are the pros and cons of neoprene rubber? ›

NEOPRENE® (POLYCHLOROPRENE) RUBBER

NEOPRENE® is resistant to ozone, sunlight, oxidation and many petroleum derivatives. Added advantages include good resistance to water, many chemicals, good resilience characteristics and high tensile strength properties. DISADVANTAGES: NEOPRENE® has few practical limitations.

What is the shelf life of neoprene O rings? ›

For example, a Neoprene O-Ring under a proper storage environment has a shelf-life of 15 years, but if these o-rings are subjected to UV radiations or heat when stored in the storage room, their useful life could become much less. The factors that affect the shelf-life includes: Stress & Strain. Humidity.

What are the disadvantages of neoprene rubber? ›

Disadvantages of neoprene

The primary disadvantage of neoprene is its cost. Several other materials offer similar characteristics at a lower price. Neoprene also offers poor resistance to strong oxidising acids, esters, ketone and certain hydrocarbons. Other rubber materials deliver superior oil resistance.

What is another name for chloroprene rubber? ›

Chloroprene rubber (CR) is a synthetic rubber that is also known by the trade name Neoprene.

How strong is neoprene rubber? ›

With a tensile of 2,500 PSI, this ultra-strength rubber is designed for maximum performance and service and exhibits high mechanical stability. BRP's ultra-strength neoprene rubber is made with 100% virgin polychloroprene polymer and demonstrates fire resistant properties.

Does neoprene crack? ›

Neoprene can survive in outdoor conditions longer compared to natural rubber because of its resistant to ozone and oxidation. This allows Neoprene to not be worn out and cracked when exposed to an outside environment. The biggest disadvantage of Neoprene, however, is the relatively higher cost of the material.

Why is neoprene so expensive? ›

Among the petrochemical-derived fabrics, Neoprene is one of the most costly. This textile is relatively difficult to produce, and its beneficial attributes drive its price upward even further.

What is the strongest type of rubber? ›

Nitrile. Nitrile (also known as Buna-N) is a copolymer of butadiene and acrylonitrile and one of the strongest rubber materials in applications involving oil and fuel.

What are the advantages of chloroprene rubber? ›

Chloroprene rubber has a combination of several technically essential properties, such as good mechanical properties, heat resistance, ozone and weather resistance, flame resistance and adequate electrical properties, which are not obtained with other synthetic rubbers. Thus, it has a broad spectrum of usage.
