TPU or Thermoplastic Polyurethane is the latest development in the materials used in the manufacture of cellphone covers. TPU covers allow for superior protection through increased flexibility, durability and shock absorption capabilities. The covers are thinner, more light weight and more durable than conventional covers. TPU covers have the ability to retain the polished look of hard plastic but their flexible properties make them more scratch, finger print and oil resistant than conventional covers.
