Today,  India produces about 3.5 million tons of  uncoated woodfree paper, MTI’s primary  end market for PCC, and is growing by more  than seven percent a year. China produces  16.5 million tons of uncoated woodfree— more than both North and South America  combined—and is growing more than six  percent per year. In India, the penetration of PCC, defined as tons of PCC produced and sold into  paper, is nine percent, or a little over  300,000 tons, up from 4 percent. In China,  the penetration of PCC is about 7 percent, or 1.2 million tons. As a comparison, the PCC penetration rate in  North America and Europe is approximately  20 percent—two to three times that of  India and China, respectively. These two  countries are installing state-of-the art paper  machines, and there is significant room to  increase PCC penetration to the 20 percent  Western levels.  At a PCC penetration rate of 20 percent—as  indicated by the blue bar—PCC consumed  in these two countries will increase by 2.6  million tons. Additionally, applying the  historical six percent growth rate of paper  production of over a five-year period—as  shown by the green bar—the near-to- medium-term market potential grows by  another 1 million tons, for a total of 3.6  million tons of PCC.  For perspective, in 2013, Minerals  Technologies sold 3.3 million tons of PCC  for paper, so the Asia growth potential  represents more than a doubling of our  current volume sold to the industry.  In addition, North American satellite PCC  plant expansions are moving forward and  we expect them to be contributing volume  growth in 2014. Minteq International also continued to  expand around the world. This business  unit, which consists of Refractories,  Metallurgical Wire and the Ferrotron  equipment product lines, primarily services  the worldwide steel industry.  Refractories growth was driven by a full  service contract for a new steel mill owned  by United Steel Company B.S.C. (SULB) in  Bahrain. This three-year contract, begun in  October 2012, will contribute $25 million to  $30 million in sales over a three-year period.  Traditionally Minteq’s focus has been on  sales of monolithic refractory products that  are applied onto the linings of steel-making  vessels in order to extend service life. Under  this agreement, Minteq, working with other  refractory companies that produce brick,  is responsible for coordinating all refractory  maintenance of the steel furnaces and the  other steel-production vessels. Also, in the Middle East, Minteq signed  three maintenance contracts for refractory  material, its Minscan® application  equipment and manpower services at three electric arc furnaces. In Metallurgical Wire, Minteq’s growth was  primarily driven by geographical expansion  into India, Turkey and Russia.  Minteq and Performance Minerals  Geographic Expansion Minteq International
