Chiarotti Brazil

     The Chiarotti family, now in its third generation, is responsible for the introduction in the country of the manufacture of porcelain products for laboratories. It is also heavily involved in the development of the production of medium and low voltage insulators from the pioneer Ceramic Industry Cerqueira Leite Ltda through industries in the interior of the State of São Paulo until the formation of the current enterprise.

In the 1960s the entrepreneur Nelson Chiarotti started the tests in a “pioneer” way, at night and at weekends, from the need to use resistant materials in the laboratory tests of metallurgy, for the production of support hardware of insulators for medium and low voltage.

In tests with carbon, silicon, phosphorus, sulfur and manganese only the imported laboratory articles resisted. Navicles and crucibles were produced in the then Porcelana Mauá S.A., company whose true vocation was the one of the porcelain table.

With the achievement of results from the home tests created its own policy of import substitution, which would be a major macroeconomic objective in the years that followed.

In the segment of laboratory materials, the products are recognized for quality and greater resistance to thermal shock, without cracks or breaks – they support temperatures up to 1100º C and shock 800 to 20º C.

Currently Chiarotti operates in other important markets for the Brazilian industry – in the manufacture of refractory parts such as wire guides, threads, tubes among others; in the development of special parts – according to technical drawing – meeting the engineering needs of each company; and in the manufacture of exclusive parts with its own brand – in the outsourcing format.
