Description

Nitrile (or NBR) O-Rings are most commonly available and are cost effective.Ideal for use as seals on pumps, drive belts, and other general engineering applications.
NBR is good for applications that need to withstand fats, Greases and high temperature (+70°C).
For automotive applications requiring contact with petrol or diesel you may wish to consider Polymax Viton o ring kits

Available with the following Approvals/Certifications. Please call for further information.

Viton O-rings

Description

FKM (Viton®) O-rings have excellent chemical resistance and can be used at temperature range of between 15°C and 200°C. Although generally more expensive than NBR (Nitrile) O-rings, FKM has found wide acceptance in the aircraft, automotive and chemical industries.

The terms FPM, FKM and Viton® can lead to incorrect interpretations. These designations stand for one single base material: fluorocarbon rubber.

Polymax is also able to supply specially compounded FKM O-rings meeting Norsok M710, FDA, USP Class VI, UL94 V0, EN549, Viton® A, B, G, GF, GLT, GFLT, ETP standards on special request. Please contact us for further information.

Informatie

EPDM-materialen zijn in de regel goed bestand tegen heet water, waterdamp, veroudering en chemicaliën en maken vele thermische toepassingen mogelijk.

Zij worden onderverdeeld in met zwavel en peroxide gevulkaniseerde typen, waarbij de peroxide mengsels thermisch hoger belast kunnen worden en een duidelijk geringere vervormingsrest vertonen.

Silicone O-rings

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
    • Ketones (MEK, Acetone)

Informatie

PTFE is een gefluoreerde kunststof. PTFE heeft een groot aantal positieve eigenschappen, die in de afdichtingstechniek onmisbaar zijn geworden. Hij onderscheidt zich door zijn bijna universele resistentie tegen chemicaliën, toepasbaarheid bij temperaturen van -200°C tot +250°C en een uiterst geringe wrijving. Het resultaat hiervan zijn zeer goede glij eigenschappen, geen stick-slip-effect, bijzondere stijfheid en een bijna onbegrensde ozon-, weer- en verouderingsbestendigheid.

Verkrijgbaar met de volgende Certificaten. Zoek contact op voor meer informatie.

Temperature Range

  • Up to 250°C (Intermittent)
  • Down to -200°C

Chemicaliën weerstand

  • Universele resistentie tegen chemicaliën
  • Verouderingsbestendigheid en heeft een oneindigend Plankleven
  • Is voor farmaceutisch en medisch gebied uitermate geschikt
  • Alleen elementaire fluor en alkalimetalen tasten PTFE bij hoge temperaturen en druk aan.

Niet geschikt voor:
  • PTFE is niet of slechts weinig elastisch en is dus niet geschikt voor dynamische toepassingen
  • Hoge vacuümafdichtingen
  • Hoge temperatuur stoom.
Neoprene O-rings;

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
