Description
DA-100, DA-418 is acrylic copolymer with high molecular weight (HMW) and super melt strength. It is processing
aid for general purpose and it can obviously improve melt strength of PVC compound, prevent bubble from melt
and crack to get more homogeneous foaming structure and low density of product. It also can improve surface
gloss of PVC product.
It is white flowing powder. It can be dissolved in ketone and chloroform, but not in water and alcohol
