The BRB-900A Blocking Tester is economical and easy-to use for film and sheet blocking spot checks and quality control. It was designed to measure the undesired static adhesion which can exist between layers of certain types of plastic films. The BRB utilizes a compact mechanical balancing system that incrementally adds weight equivalent to 90 ml per minute of water.
Through use of this system, the BRB can increase the precision and speed of blocking tests and meets or exceeds all conditions specified by ASTM D3354. The BRB Tester features a magnetic clamp to securely hold the sample in place, eliminating the need for tape. The force required for separation is shown in tenths of a gram on an onboard display. All variables are monitored electronically to maximize accuracy and repeatability.
