Known Application

UV一856 is a new multifunctional nylon additive that combines several beneficial properties in one molecule. Due to its unique molecular structure, UV-856 is resistant to the reductive environment of nylon melts and acts as a melt stabilizer and processing modifier. This effect has been proved by the high stability of nylon melt pressure and results in high quality nylon injection and extrusion Products, as well as lower yarn breakage rates during fiber spinning.
