in Polymer Applications:
Wolkem’s uncoated and surface modified milled
and Micronised grades are excellent low cost filler
for Polymer compounding, Master-Batches, PVC Rigid
Pipes, Profiles, Doors and Windows.
- Better mechanical properties then any other
filler such as better dispersion, reinforcement
- Lowers cost of production.
- Lowers Resin deman
Wolkem’s Uncoated & surface modified
HAR Wollastonite grades provide excellent dimensional
stability, tensile strength, improved flow and
high heat distortion temperature, scratch resistance
in Nylon, PBT, PP, SMC, DMC, Epoxy, and PC Compounds.
Wolkem’s Wollastonite provides significant advantages
such as higher loading improved product flow,
product uniformity, scrape reduction, lower initial
viscosity and faster mold cycles. This also has
low water absorption, low electro-conductivity
& low resin demand.
Wolkem’s Talc having high whiteness is supplied
for polymer compounding and for Master-Batch application
for various polymers such as Polypropylene, HDPE,
LDPE, LLDPE etc.
This gives best mechanical properties comparing
with other fillers as well as surface finish
