UHMW Plastic’s Water Absorption

UHMW plastic’s water absorption degree is very low ,the value of it is less than 0.01% .That means 1000g UHMW Plastic products immersed in water has only a very tiny expansion rate ,almost can be ignored ,the volume expansion is less than 0.01% .

Because UHMW plastic does not absorb any water ,the physical property is stable .Even after 10 years immersion ,the size ,the density ,or any other index will be changed .The water absorption is a very important parameter for various plastics ,once the plastic absorb water ,the infiltrated water will have chemical reaction with inner molecules ,so the damage degree is inestimable .With many tests results ,the people finally adopts UHMW plastic as fenders material .
