Micronized Rubber Powder
What separates ultra-fine MRP from coarse crumb rubber, how our ambient grinding line reaches 170 mesh, and the four application areas it serves.

Key takeaways
- Crumb rubber is vulcanized rubber granulate recovered from scrap tyres, with all steel and textile reinforcement removed.
- Grades run from 10 mesh coarse granules for turf infill and flooring down to 80 mesh micro-powder for friction goods and brake pad rubber powder.
- AP Rubber Group processes 100% Truck and Bus Radial (TBR) feedstock, which carries higher natural rubber hydrocarbon content than passenger car tyres.
- Production is a four-stage ambient line: feedstock selection, mechanical shredding, magnetic and pneumatic extraction, then precision sieving.
- Replacing virgin polymer with crumb rubber typically cuts raw material overhead by 15% to 30%.
At AP Rubber Group, operating state-of-the-art facilities in Haridwar (India) and Oman, we engineer premium recycled polymers derived exclusively from 100% Truck and Bus Radial (TBR) tire feedstock. As a premier Crumb Rubber Supplier and global Crumb Rubber Exporter, we deliver clean, high-performance rubber solutions to industrial clients worldwide.
What is Crumb Rubber & Rubber Powder?
Crumb Rubber consists of high-grade vulcanized rubber granules liberated from recycled scrap tires. Through advanced processing, all steel wires and textile reinforcement fibers are completely removed, leaving pure, elastic polymer granules.
Depending on particle sizing (mesh grading), the material spans from coarse granular crumb to micro-fine natural rubber powder and reclaimed rubber powder.

The Advanced Crumb Rubber Manufacturing Process
To maintain ultra-low contamination levels, AP Rubber Group executes a multi-stage Crumb Rubber Manufacturing Process powered by heavy-duty ambient mechanical grinding.
- 1
100% TBR Feedstock Selection
We strictly process heavy-vehicle TBR tires, ensuring significantly higher Natural Rubber Hydrocarbon (RHC) and tensile strength compared to standard passenger car tires.
- 2
Mechanical Shredding
Heavy-duty dual-shaft shredders reduce whole tire carcasses down to consistent chips while liberating structural steel.
- 3
Magnetic & Pneumatic Extraction
High-intensity cross-belt magnetic separators pull out 99.9% of steel wire, while specialized pneumatic aspirators strip away all textile fluff.
- 4
Precision Sieving
Vibratory screening arrays precisely separate clean particles into exact gradations — from 10 Mesh down to micro-fine 80 Mesh.
Specialized Focus: Brake Pad Rubber Powder & Friction Materials
In automotive safety engineering, Brake Pad Rubber Powder is vital for optimizing friction performance. Incorporating high-purity reclaimed rubber powder or micro-mesh natural rubber powder into brake friction linings delivers key operational advantages:
- Noise & Vibration Elimination — Dampens high-frequency brake squeal and harshness (NVH dampening).
- Thermal Friction Stability — Maintains reliable, consistent braking force across extreme temperature fluctuations.
- Extended Wear Life — Increases friction pad elasticity, preventing surface micro-cracking under heavy usage.
Why Choose AP Rubber Group?
- Unmatched Hydrocarbon Content — Premium TBR tread stock delivers maximum elasticity and tensile strength.
- Purity Guarantee — Ultra-clean rubber with < 0.1% steel and textile contamination, protecting your processing equipment.
- Substantial Cost Savings — Reduces raw material overhead by 15% to 30% when replacing expensive virgin polymers.
- Strategic Dual-Facility Supply — Manufacturing hubs in Haridwar (India) and Oman ensure fast, uninterrupted global exports.

Frequently asked questions
What mesh size of crumb rubber do I need?
It depends on the application. Use 10 mesh for athletic turf infill, playground surfaces and rubber flooring; 20 mesh for crumb rubber modified bitumen (CRMB) asphalt and moulded speed bumps; 30 mesh for NVH underbody coatings and sealants; 60 mesh for rubber compounding, conveyor belts and hoses; and 80 mesh for precision extrusions, friction goods and brake pad rubber powder.
How is crumb rubber manufactured?
Through a multi-stage ambient mechanical grinding process. Whole TBR tyre carcasses are shredded by dual-shaft shredders, cross-belt magnetic separators remove 99.9% of the steel wire, pneumatic aspirators strip out textile fibre, and vibratory screens sort the clean granulate into exact mesh gradations.
Why is TBR tyre feedstock better than mixed scrap tyres?
Truck and bus radial treads are engineered for heavy loads and continuous abrasion, so they carry a higher natural rubber hydrocarbon content and greater tensile strength than passenger car tyres. Using a single, consistent feedstock also gives more reliable batch-to-batch quality.
What is brake pad rubber powder used for?
It is blended into brake friction linings to dampen high-frequency squeal and harshness, hold braking force steady across extreme temperature swings, and extend pad wear life by keeping the friction material elastic enough to resist surface micro-cracking.
