LTTPs do have a limited shelf life as these materials are made from organic components that are vulnerable to environmental factors. UV rays, heat and humidity, bacteria and germs can all have a negative effect on the thermoplastic material causing breakdown. Always store your splinting materials flat in a dry, dark place for maximum benefit.
Each product has a label indicating its expiration date which varies from three to five years, depending on the product. If your product has been sitting on the shelf for longer than the expiration date on the label, it may not perform as expected. It may become brittle, discolored and overly stretchy. So, it is important to carefully manage your inventory of materials and to adopt the first-in – first-out principle.
