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.

Temperature Range

  • Up to 120°C (Intermittant)
  • Down to -30°C

Avoid prolonged use at higher extremes

Chemical resistance

  • Many hydrocarbons
  • Fats
  • Oils & Gasoline
  • Petroleum based hydralic fluid (HFD-R)

Generally atacked by:
  • Ozone
  • Esters
  • Retones
  • Aldehydes
  • Chlorinated
  • Nitro Hydrocarbons

Description

FKM (Viton ®) O Rings have a low compression set and have high temperature and chemical resistance. More expensive than NBR O Rings.

The terms FPM, FKM and Viton® very often cause confusion and lead to incorrect interpretations. All of these designations actually stand for one single base material:fluoro rubber.

NORSOK approved compound also available on request.

Available with the following Approvals/Certifications. Please call 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.

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.

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.
