Rubber Powder

Product Description

Micronized Rubber Powder (MRP) is classified as fine, dry, powdered elastomeric crumb rubber in which a significant proportion of particles are less than **0 µm and free of foreign particulates (metal, fiber, etc.). MRP particle size distributions typically range from **0 µm to *0 µm. Narrower distributions can be achieved depending on the classification technology.
MRP is a free flowing, black rubber powder that disperses into a multitude of systems and applications.[1] Due to its micron size, MRP can be incorporated into multiple polymers, and provides a smooth surface appearance on finished products. In some cases, in order to improve compatibility with host materials, the MRP is given a chemical treatment to activate, or make functional the surface of the powder particles. This is referred to as functionalized MRP or FMRP.

MRP represents an evolution over previous post-manufactured rubber technologies. The most basic rubber processing technology converts end-of-life tire and post-industrial rubber material into rubber chips that are typically one inch or larger in size. These chips are then used in tire-derived fuel and civil engineering projects.[2] A second-generation processing technology converts end-of-life tire and rubber material into crumb rubber, also known as ground tire rubber (GTR). GTR typically comprises chips between one inch and *0 mesh in size, with the associated fiber and steel mostly removed. This material is used in asphalt, as garden mulch and in playgrounds.[3]

MRP is a micron-size material that is produced in various sizes, including *0 mesh and down to **0 mesh. MRP is virtually metal and fiber-free, enabling its use in a wide range of advanced products.
