  Graphites and Cokesfor friction materials  TIMCAL Group has a strong traditionand history in graphite manufacturing. Itsfirst manufacturing operation was foundedin 1908. Today, TIMCAL Group facilitiesproduce and market a large variety of syn-thetic and natural graphite powders anddispersions of consistent high quality.Adhering to a philosophy of Total Quality Management and continuous processimprovement, all TIMCAL manufacturingplants comply with ISO 9001-2000.TIMCAL is committed to produce highly specialized graphite and carbon materialsfor today’s and tomorrow’s friction materi-als industries.TIMCAL has an international pre-sence with facilities and commercial officeslocated in the key markets around theGlobe. The Group’s industrial and commer-cial activities are implemented by an experi-enced multi-national team of nearly 300employees from seven countries on threecontinents.TIMCAL Group is a member of IMERYS, a world leader in adding value tominerals. Who are we? Rapid developments over the past few years within the automotive industry haveresulted in a growing demand for high-qual-ity friction materials.The main requirement to be met by abrake lining is, besides a high level of energy absorption, a high brake efficiency within awide temperature range. Comfort aspects,life-time, and absence of noise are factorswhich also demand important considera-tion.These requirements are fulfilled by meansof high performace brake pads in which car-bon powders such as graphite and coke play a key role.The extreme consistency of TIMREX  ® Carbons provides the predictable propertiesthat makes development and productionvery efficient.This documentation is intended to helpour customers make the best possible selec-tion from the wide range of TIMREX  ® Graphite and Coke materials available foruse in their high performance friction appli-cations. About frictionmaterials TIMREX  ® Graphites combine technicaland economic advantages: their optimalprice/performance ratio helps maintaing a high quality level in the finished part while, at the same time, reducing manufacturing costs.

Timcal mines thegraphite from its own source in Lac-des-Îles,Quebec, Canada. This unique “close-to-cus-tomer” location guarantees very fast andreliable deliveries.All TIMREX  ® “Naturals” are thoroughly controlled in our laboratories to ensure qual-ity, consistency and above all, total customersatisfaction. TIMREX ® Coke TIMREX  ® Petroleum Coke is calcined atappropriate temperature with low ash andsulfur content, well defined texture and con-sistent particle size distribution. TIMREX ® Primary Synthetic Graphite TIMREX  ® Primary Synthetic Graphi-tes are produced in a unique highly con-trolled graphitization process wichassures narrow specifications andunequalled consistent quality due to:monitoring of all production and pro-cessing stages, strict final inspection, andclearly defined development processes.TIMREX  ® Primary Synthetic Graphi-tes show unique properties thanks to thecombination of a consistent purity, per-fect crystalline structure and well definedtexture.  T Graphite T 75T 15-75T 150T150-600T 800T 200-2000 Particle size range d ( µ m) * Scott density* Scott density 0 500 1000 15000 500 1000 15002000 KS Graphite Particle size range d ( µ m) Ash(%)Moisture(%)CrystalliteheightLc (nm)> 100> 100> 100> 100> 100> 1000.21*0.33*0.510.590.640.730.> 100> 100> 100> 100> 100> 1000.24*0.41*0.600.800.770.72 Tapdensity(g/cm 3 )DBP absorbtion (Dibutylphthalate) (g/100g) 1037059233321984552251714 KS 75KS 5-75TTKS 150KS 500KS 150-600SPKS 300-1250 Typical values TIMREX ® Carbons forFriction Materials
