ASA Polymer resin is a ternary copolymer consisted of Acrylonitrile, Styrene and Acrylate. ASA Copolymer integrates acrylates's high impact strength and excellent weather-resistance, chemical resistance and high hardness of acrylonitrile, good processability of styrene. It can be extruded single & coextruded over ABS and PVC. ASA is particularly used in outdoor applications that require long term color stability, excellent weather resistance.

Package & Storage
IH801 is delivered in the form of cylindrical or spherical pellets. The bulk density of the pellets is from 0.55 to 0.65 g/cm³. Values may differ for special grades.
Standard Package:25kg or 1000kg PE-bag on pallet, shrink or wrapped with PE film.
In dry areas with normal temperature control, IH801 pellets can be stored for relatively long periods of time without any change in mechanical properties.
With unstable colors, however, storage over a number of years can give rise to some change in color. Under poor storage conditions, IH801 absorbs moisture, but this can be removed by drying.
