High-Performance Polyurethane Film
Polyurethane is a very tough, chemically resistant elastomer. The following tables can give you insight into how polyurethane material reacts to a number of different compounds. Each of the tests were performed at room temperature.
Please Note: Chemical resistance typically improves as the material's durometer increases.
KEY:
E - Excellent: little or no damage
G - Good: slight loss of properties, slight swell
F - Fair: swelling and some loss of properties
P - Poor: significant loss of properties and significant swelling
D - Dissolves
