Core Advantages

Production meets PDA industrial standard with stable batch purity;
Moderate DBP value leads to mild viscosity rise after addition, no die clogging during extrusion & easy demolding for injection;
Dual functions of tinting and anti-static, no extra pigment carbon black needed for black finished goods;
Good compatibility with natural rubber & engineering plastics, no blooming during processing.

Main Applications

Core Fields: Anti-static plastic masterbatch, conductive rubber, anti-static injection molding parts
Compatible Fields: Anti-static anti-corrosion industrial topcoat, functional color paste

Usage Notes

Only suitable for medium & low anti-static grades; increase loading and conduct pre-test for ultra-high conductivity demand;
Resistivity changes after mixing with general pigment carbon black; re-test anti-static index before molding;
Store in ventilated dry warehouse, do not stack with strong oxidants.
