Consists of polished stainless steel plate which is clamped in the lower grip. One end of the sample is adhered to the plate and the other end is held in the upper grip. The sample is peeled off of the plate and the strength is measured. The upper grip is typically lightweight to enable the use of a small load cell.
This fixture utilizes a sliding sample plate to maintain a 90° angle while measuring peel force. The adhesive sample is attached to the plate while the opposite end is secured by the upper grip.
Measures peel strength at 90° to a surface. The adhesive backed sample is wrapped around the wheel, and the end of the sample is folded back on itself to provide an adhesive free area which is clamped into a grip. Samples can be tested in widths up to 50 mm (2 in).
Type: Pressure sensitive adhesives, tapes, and labels.
Measures the tack (instant grip) of the specimen by
lowering the looped material until it makes contact with a stainless steel plate and then measuring the force required to release the sample. The plate is attached with a tab that is placed in the lower grip.
