The patented NITROdry resin dryer provides processors with a new, oxygen-free tool to avoid degradation of nylons, PBT, PLA and TPU’s that is the result of prolonged exposure to heat in the presence of oxygen. The first, self-contained, oxygen-free dryer is ideal for press-side drying of newly designed polymers with unique properties. These materials can suffer degradation of performance with respect to strength, ductility, color (opaqueness), viscosity, chemical resistance, stiffness and stability due to extended exposure to heat and oxygen.
