Steel fibers Denomination of the product : Strongly carbonaceous steel fibers and filings (resulting from the recycling of tires). Origin of the product : Strongly carbonaceous steel fibers and filings resulting from the recycling of used tires of various categories (pv, cv, gv, hgv, pwv, cev, iv, agrarian, handling, motorbikes, etc.). All the technical features of these tires comply with the regulations and standards requirements of france and of the european union. Composition of the product : The steel is a strongly carbonaceous steel. The small rubber buffings mixed with the steel fibers and filings are made of a mix-in variable proportions of 2 main types of synthetic rubber and of natural rubber. The 2 types of synthetic rubber are : - the sbr (styrene butadiene rubber) - the nbr (nitrile butadiene rubber) [cf. The specifications sheets of the products : 'rubber crumbs' and 'fine rubber powder']. The textile filling and fluff mixed with the steel fibers and filings is made of a mixture of 4 types of fibers : aramide, nylon, polyester and rayon (mainly nylon, that is to say polyamide) [cf. The specifications sheet of the product: textile filling and fluff]. Apparent density ( without compressing) : 238 kg / m3 or 0, 238 [+ or - 5 %] (adimensional). Industrial process of manufacturing : Exclusively with a mechanical crushing of the tires at ambient temperature. The process used does not require and does not reject any kind of solid, liquid or gas additives. Mass distribution of the constituents : - steel fibers and filings : 95, 1 % + or - 2, 7 % - rubber buffings : 3, 3 % + or - 1, 4 % - textile filling and fluff : 1, 6 % + or - 1, 3 % Lengths interval of the steel fibers : [1, 00 + or - 0, 02 mm -> 100, 36 + or - 0, 02 mm]. Diameters interval of the steel fibers : [0, 26 + or - 0, 02 mm -> 4, 73 + or - 0, 02 mm]. In bulk in 40' dry hc (high cube) container
