Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If standard rotomolding LDPE
Conventional rotomolding grades typically <1.44 relative viscosity.
If contains polycolor pigments > specific threshold
Heavily pigmented polymers may classify as paints/varnishes if pigment dominates.
If masterbatch with additives >5%
Polymer concentrates/masterbatches with significant additives shift to prepared binders heading.
