The Universal Selection Source: Plastics & Elastomers


Haze

Haze is measured as the percentage of incident light scattered by more than 2.5° through the plastic specimen. Haze is caused by impurities contained in the plastic material or its level of cristallinity. The lower the Haze value, the higher the clarity. If Haze value is greater than 30%, the material is diffusing. Hazemeters and spectrophotometers are used to measure the level of Haze.

Haze has no specific unit. It is expressed in %.

Haze of plastic materials is usually measured by ASTM D1003.
