Polypropylene Wax

VISCOL Products
Preface
SANWAX (polyethylene wax) and VISCOL (polypropylene wax) are widely used in various industries
by taking advantage of each feature.
For example, these products are used as pigment dispersants for color masterbatches (colorant formolding resins) because they have high dispersibility of pigment. They are also used as scratch
inhibitors and anti-blocking agents for printing ink because they have moderate hardness.
UMEX products are also offered. They are modified low-molecular-weight polyolefins that havecarboxylic anhydride groups as functional groups.

FeaturesSANWAX and VISCOL have following features:· Have low melt viscosities approximately equal to those of paraffin wax.
· Have high softening point equivalent to that of polyethylene and polypropylene.
· Have hardness equivalent to that of polyethylene and polypropylene.
· Have high dispersibility of pigment.
· Generally not compatible with other resins except polyolefin.

Important :Before handling these products, refer to the Safety Data Sheet for recommended
protective equipment, and detailed precautionary and hazards information.

Precaution Against Mishandling· When the SANWAX/BISCOL products are excessively added to the resin, these products may have
Negative effects on resin’s physical properties. Test the effects on each of the physical properties
beforehand to ensure that there are no problems.
· As shown in Table 1 on page 1, the compatibility with certain molding resins is insufficient, therefore
the transparency may be affected. Before using the SANWAX/BISCOL products, confirm thecompatibility with resins
