Selection guide

How to choose your WMB grade

Q: Need maximum opacity?
Choose Flagship tier — WMB-PE7215 or WMB-PE8015 (72–80% TiO₂).
Q: Cost-performance balance?
Mainstream tier — WMB-PE7026E (best seller) or WMB-PE6326.
Q: EVA foam shoe materials?
WMB-EVA7025P/E/A — specially engineered with EVA-18J3 carrier.
Q: Polypropylene applications?
WMB-PP6035P — high-fluidity PP carrier, MFR 30.
Q: Budget-conscious opacity?
TOSP series with CaCO₃ extender, or Standard tier (50–59%).
Q: Bluish or neutral undertone?
P grades = bluish/neutral-blue. E grades = neutral/milky undertone.
