Thermoplastic trays have good shape stability. Even if they are immersed in boiling water for a long time, the trays will not be severely deformed or shrunk, so that they cannot be used.
High transparency. The molded trays can maintain high transparency and are particularly suitable for use with cold light whitening devices.
Good thermoplasticity. Compared with similar products, thermoplasticity has obvious advantages and is particularly suitable for home use. The gum line is very clear.
Repeated molding is possible. Due to the uncertainty of water temperature and immersion time, the tray molding effect is often poor. Even if this product is poorly molded, it can be remolded in 150℉-190℉ hot water, which is not available in other products.
