About Polyurethane 

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
