How AquaCast Liner Works
AquaCast Liner is made with expanded polytetrafluoroethylene (ePTFE) which contains billions of tiny pores that are much larger than moisture vapor molecules but much smaller than liquid water droplets. The AquaCast waterproof liner remains dry while your skin gets wet. Water will drain quickly out of the ends of the cast. The patient’s body temperature heats up the remaining water causing it to vaporize and pass through the liner and the fiberglass cast tape. All AquaCast Liner products are not made with natural rubber latex.
