PET MODIFIER MB 02(S 91127)

PET intrinsic viscosity modifier masterbatch with elastomer as carrier polymer. It raises intrinsic viscosity of PET scrap material during extrusion. It increases molecular weight and improves melt strength, hydrolytic stability and mechanical properties. It upgrades lower molecular weight poly condensate polymers and prevents splitting. Used in PET box strapping. Its dosage rate is 1.5 - 2.5%.
