Reducing particle size (sometimes referred to as Crumbing) reduces heat transfer rates, increases surface area and causes the material to melt more uniformly. This improves overall batch quality and consistency between batches. This is especially beneficial to markets requiring additional processes, such as compounding and rotational molding.
Rubber can be crumbed into a particle size as small as 1/8″ (4.76mm). Our wide range of rubber particle size allows it’s use in many different applications
ECM produces Crumbed Rubber for a variety of end use applications such as adhesives, brake pads and tires. Crumb rubber has other applications, including ground cover under playground equipment, running track material, and as a soil additive in sports and playing fields. Other uses for crumb rubber include molded rubber products (e.g., carpet underlay, dock bumpers, patio decks, railroad crossing blocks and movable speed bumps); new tire manufacturing; automotive parts such as brake pads and shoes.
