Frequently Asked Questions (FAQ)

Q1: What is E3490 prepolymer?

A: E3490 is low-viscosity TDI-terminated PTMG prepolymer, the main A-component paired with MOCA to cast heavy-duty mining polyurethane wear parts.

Q2: Key mechanical advantages for mining use?

A: Shore A90 hardness, 33MPa tensile strength, 78kN/m tear strength, ultra-low DIN abrasion (39mm³), long service life against mineral slurry erosion.

Q3: Compatible with our CPU casting machines?

A: Fully fits 5~15kg/min & 10~30kg/min two-component casting machines for small & oversized mining PU parts.

Q4: Can we add color pigment?

A: Yes, color paste can be added via the machine’s color feeding unit without weakening wear resistance.
