NX-530 is ultra-high molecular weight acrylic copolymer with
multi-layer structure. It can promote the processability and
plasticization, improve hot-melt strength and viscoelasticity, and
thus achieve good surface quality with uniform and dense foam
structure of PVC products. It can be dissolved in chloroform and
methyl ethyl ketone, can not be dissolved in water and ethanol.
NX-530 iswidely used in rigid PVC, such as window profiles, siding,
fences, roofing sheets, pipes, fittings, injection-molded parts,
wood-plastic composites and foamed products. The recommended dosage
for foamed products is 5-8 phr for 100 phr PVC resin.
