Polyols​

    Polyols, including polyethylene glycol (PEG) and polypropylene glycol(PPG), require filtration after neutralization or catalyst removal steps.JOECHRE filters handle these viscous media efficiently, producingdry, non-sticky filter cake and supporting consistent product quality.Their enclosed design and ability to perform heel volume filtrationreduce product losses and limit manual handling. In many cases, filteraid consumption is reduced or eliminated due to the fine syntheticfilter cloths, lowering operating costs and simplifying validation inpolyurethane precursor production.
