Advantages

When jointly used with non-toxic zinc-based stabilizers, “PLENLIZER” remarkably improves heat stability of vinylchloride resin by preventing the resin from getting zinc burning. “ST” Series, ester-type products made from carboxylic acid and polyalcohol, are listed in the Positive List of Japan Hygienic PVC Association. “HC-103S” works as an efficient HCl gas catcher which is heavymetal-free.
