Micronized Rubber Powder (80–170 mesh)
Ultra-fine rubber powder (50–300 micron) produced from scrap tyres by ambient grinding and micronisation; positioned as a functional filler, not just a diluent.

Key properties
- Particle size 50–300 microns
- Highly fractured surface with very high surface area
- Strong mechanical interlocking with virgin polymer
- Specific gravity ~1.12–1.13
- Minimal loss of tensile, elongation and abrasion at 10 phr
