As568 Standard PU 90shore Excellent Wear and Abrasion Resistant Polyurethane O Ring​

Introduction for O Rings

Material description for Polyurethane/PU Rubber O-Rings

Polyurethane is an organic polymer. Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl

groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Polyurethane

is a widely used compound due to its superior strength, tear and abrasion resistance. Polyurethane also provides excellent permeation

resistance.

Features:

• Good hydraulic oil and gasoline resistance
• Resistant to pure aliphatic hydrocarbons (propane, butane, fuel)
• Resistance to mineral and silicone oils and greases
• Resistant to water, oxygen, ozone and aging
• Excellent tear and abrasion resistance
• Available in multiple types and compounds to meet performance and cost requirements

Limitations:

• Not compatible with acids, ketones, esters, ethers, alcohols, glycols
• Hot water, steam, alkalis and amines

Service Temperature:

-65° to 225° F (-54° to 107° C). Depending on compound and application

Following elastomers can be use in O ring :

* Aflas® or Kalrez®(FFKM)
* Acrylate Rubber(ACM)
* Butyl Rubber(IIR)
* Ethylene-propylene (EPR, EPDM)
* Ethylene Acrylate Rubber(AEM)
* Fluorocarbon (FKM/FPM/FKM)
* Fluorosilicone(FVMQ)
* Hydrogenated Nitrile (HNBR)
* Neoprene Rubber(CR)
* Nitrile Rubber (Buna-N/NBR)
* Natural Rubber(NR)
* Polyurethane(PU)
* Silicone Rubber
* Styrene-butadiene Rubber (SBR)
