Tire manufacturer Dunlop's Indian company goes bankrupt
Recently, the High Court of India has appointed an official to head the bankruptcy liquidation of Dunlop (India). In the past few years, this tire manufacturer in Calcutta has operated only occasionally. Dunlop Indian Company announced on the stock exchange that the Calcutta High Court notified the company’s lawyer on March 26, 2012 regarding the appointment of an official liquidator.
Dunlop India was once part of the Dunlop International Group and has been under the control of the Ruia Group in India since 2005. The company’s factories in Ambattur, Tamil Nadu, and Sahaganj, East Bangladesh have been idle many times since then and ended the nine months ended December 31 last year. The results show that its sales amounted to 3.9 million U.S. dollars and its net loss was about 170,000 U.S. dollars. Revenue decreased by 90% compared to the same period in fiscal 2010.
Luya Group is a transnational large-scale industrial conglomerate and holds shares in many companies in the tire , rubber and heavy machinery industries. Its holding companies in the tire industry are Falcon Tire Company and Monotona Tire Company.
Asbestos was added as an common ingredient to Brake Pads post-WWI, as car speeds began to increase, because research showed that its properties allowed it to absorb the heat (which can reach 500 °F) while still providing the friction necessary to stop a vehicle. However, as the serious health-related hazards of asbestos eventually started to become apparent, other materials had to be found. Asbestos brake pads have largely been replaced by non-asbestos organic (NAO) materials in first world countries. Today, brake pad materials are classified into one of four principal categories, as follows:
Non-metallic materials - these are made from a combination of various synthetic substances bonded into a composite, principally in the form of cellulose, aramid, PAN, and sintered glass. They are gentle on rotors, but produce a fair amount of dust, thus having a short service life.
Semi-metallic materials - synthetics mixed with varying proportions of flaked metals. These are harder than non-metallic pads, more fade-resistant and longer lasting, but at the cost of increased wear to the rotor/drum which then must be replaced sooner. They also require more actuating force than non-metallic pads in order to generate braking torque.
Fully metallic materials - these pads are used only in racing vehicles, and are composed of sintered steel without any synthetic additives. They are very long-lasting, but require more force to slow a vehicle while wearing off the rotors faster. They also tend to be very loud.
Ceramic materials - Composed of clay and porcelain bonded to copper flakes and filaments, these are a good compromise between the durability of the metal pads, grip and fade resistance of the synthetic variety. Their principal drawback, however, is that unlike the previous three types, despite the presence of the copper (which has a high thermal conductivity), ceramic pads generally do not dissipate heat well, which can eventually cause the pads or other components of the braking system to warp.However, because the ceramic materials causes the braking sound to be elevated beyond that of human hearing, they are exceptionally quiet.
