Linear Dimension Change

Calendering or extrusion processes of nonrigid thermoplastic or film materials can often lead to variances in the dimensional properties of these materials. ARDL provides Linear Dimension Change testing to assist in measuring the uniformity of internal strain of materials for quality control. After discussing requirements with our customers, ARDL follows ASTM procedure when exposing materials to specified conditions at elevated temperatures and times.
