RRP™ (abbrev. Reclaim Rubber Powder) is a finely pulverized product from the processing of used tires or their parts. The production technology is based on mechanical recycling processes, which also employ devulcanizing agents. During the manufacture the incoming tire rubber is devulcanized, but its chemical composition is not changed. In addition, the product is cleaned from metal cords, textiles or other foreign bodies.
Two major types of RRP™ is produced from pre-selected passenger car and truck tires. Passenger car tires are used for producing RRP™ SBR. SBR rubber constitutes the largest fraction in the product.
For producing RRP™ NR truck tires are used. NR rubber constitutes the largest fraction in this product.
The products are powders. They are classified based on the granulometric fractions from 18 to 40 Mesh. 18 Mesh fraction means that the powder consists of particles, which pass through 18 Mesh sieves; 20 Mesh fraction means that the powder consists of particles, which pass through 20 Mesh sieves; 40 Mesh fraction means that the powder consists of particles, which pass through 40 Mesh sieves. The product is packaged into 25 kg bags and loaded on pallets. When stored for a longer period of time, the product might form loosely bound chunks, which easily break apart during the conventional usage of the product.
