ПВА (поливиниловый спирт)

Polyvinyl Alcohol (PVA) is a unique functional resin (high polymer) manufactured from vinyl acetate monomer (VAM) via a multi-step process. VAM is polymerized into polyvinyl acetate (PVAc) and then converted to PVA . PVA is a safe, biodegradable, water soluble polymer with a wide range of applications. We are pleased to offer the best quality and a wide range of PVA specifications listed below; Partially hydrolyzed Product namesHydrolysis (mol%)Viscosity (cps)Volatiles (%)≤Ash (%)≤PH ValueHW-0586.0-90.04.0-6.07.00.55-7HW-1086.0-90.06.0-10.07.00.55-7HW-1286.0-90.09.0-13.07.00.55-7HW-15-I86.0-90.014.0-20.07.00.55-7HW-15-II90.0-94.015.0-21.07.00.55-7HW-15-III94.0-96.016.0-22.07.00.55-7HW-17-I86.0-90.020.0-26.07.00.55-7HW-17-II90.0-94.020.0-30.07.00.55-7HW-17-III94.0-96.020.0-30.07.00.55-7HW-20-I86.0-90.027.0-34.07.00.55-7HW-20-II90.0-94.029.0-36.07.00.55-7HW-20-II94.0-96.031.0-38.07.00.55-7HW-22-III86.0-90.035.0-43.07.00.55-7HW-22-I90.0-94.037.0-45.07.00.55-7HW-22-II94.0-96.039.0-47.07.00.55-7HW-24-I86.0-90.044.0-50.07.00.55-7HW-24-I90.0-94.046.0-52.07.00.55-7HW-24-II94.0-96.049.0-57.07.00.55-7HW-26-I86.0-90.050.0-58.07.00.55-7HW-26-II90.0-94.053.0-60.07.00.55-7HW-26-III94.0-96.056.0-63.07.00.55-7
