The important physical charactoristics of mouthguard materials are tensile strength, softness, compression percent and uniform density. The
ProForm laminate maintains these characteristics best because of its heat/pressure laminating process. Tensile strength of the laminate is
excellent because of the laminate's two layers of material making up the mouthguard. Density is maintained at the pressure laminating
process so shrinkage of the mouthguard is uniformly controlled. If you want the best, the ProForm Laminated Mouthguard is the choice.
