This polyester casting tape has a knitted polyester backing which provides a safe, comfortable cast which is 100% X-ray translucent. 3M Scotchcast Poly Casting Tape has a 'low memory-stretch' characteristic due to its micro-creped backing. This enables it to conform well to body contours during application whilst minimising the risk of constriction. It is easy to use and has excellent moulding characteristics.

Lightweight for easy mobility. Stretches to conform well to contours for a more comfortable, better fitting cast. Porous weave allows the skin to breathe.
