Won't swell or deteriorate in water. Urethanes remain stable even when immersed in water as warm as 120 F for very long periods of time. Urethanes are frequently utilized because of their excellent insulating properties. However, with certain additives, electrical conductivity can be increased. Resistant to ozone and oxygen.
Urethanes are virtually immune from attack by ozone and oxygen.
This makes them the ideal for use around electrical equipment without the cracking and hardening associated with other elastomers and plastics. Wide resistance to oil, grease and chemicals. Urethanes resist attack from a wider range of chemicals and substances than most rubbers and plastics. They perform well under contact with solvents, oils, and chemicals. Urethanes resemble most plastics and other elastomers because friction against non-lubricated surfaces generally decreases with harder formulation.
