Does stretching the tape during application affect the performance?
A. When used on substrates that shrink after the tape is applied, such as extruded PVC moldings, it is necessary to stretch the tape and liner at a controlled rate with a stretch laminator. When the part shrinks, the tape will shrink at the same rate. The tape should not be stretched more than 3-4%. Controlled stretch in this range will not have an adverse effect on tape performance. However, excessive stretch can reduce the effective tape thickness and affect adhesion and stress handling performance. Q.
