Thai Tokai Carbon Product Company Limited.

In today's ever changing environment, new innovations continually emerge to satisfy evolving market needs, leading to business growth and diversification. The automotive industry, which plays an increasingly significant role in the national economy, has grown steadily and continues to expand, spurring carbon black demand.

Thai Tokai Carbon Product Co., Ltd., or TCP, was established on October 19, 1989 to produce carbon black to feed the demand of the localautomotive industry.

Located in Sriracha, Chonburi, our manufacturing plant is equipped with both state-of-the-art production facilities and experienced operators and engineers, having the capability of serving carbon black requirement.

erived from feedstock oil of high aromatic content, carbon black yields high tensile strength and elasticity when combined with rubber. TCP-manufactured carbon black is characterized by its uniform pellet size and purity. As a raw material in tyre and automobile parts production, it offers a high level of quality that matches customer needs. At present TCP provides more than 10 different hard and soft grades of carbon black products to suit varying applications namely N-134, N-220, N-234, N-326, N-330, N-339, N-375, N-351H, N-550, N-660 and N-774,
each with specific qualities such as strong reinforcement, high tensile strength and abrasive resistance, low shrinkage and high elasticity. Technological improvements in plant process have also allowed us to develop low grit carbon G-N550, G-N660 and G-N774 for very smooth surface products.

TCP's strong environmental awareness is reflected in its comprehensive measures to minimize environmental impact, starting from raw material selection to state-of-the-art and environmentally-safe production technology and above all, recovery of thermal energy from the production process to generate steam and electricity. Our co-generation facilities provide enough power for plant needs, thereby significantly reducing external power consumption. Apart from recycling excess tail gas to generate power for optimum benefit, TCP also places strong emphasis on treatment of wastes. The installation of Flue Gas Desulphurization Units enables us to effectively control emission by treating sulphur dioxide in flue gas before releasing into the atmosphere via a 100 - metre concrete stack for proper dispersion. Liquid wastes are carefully treated in waste treatment facilities to conform to waste standards before discharge.

TCP attaches much importance toward management processeys within the organization to ensure effectiveness, particularly in human resource management.

Attention is focused on continual development and growth, training and transferring technological know-how, as well as creating opportunities for career progression in an effort to motivate and retain a team of dedicated employees.

With determination to satisfy customer needs. TCP is committed to the continuous improvement of product quality and product grades. Our successful attainment of the Quality Management System ISO 9001 accreditation for quality management system. ISO 14001 for environmental management system and certification for occupational health and safety management system bear evidence to our strong sense of commitment, our internationally accepted standards, and our competitiveness as a forefront carbon black manufacturer aspiring to meet every customer expectation.

Precision is applied in every stage of the production process in an effort to produce quality products through the following integrated processes.

Feedstock oil, or a hydrocarbon compound from oil refining, is fed into an oil preheater and heated at 200 degrees Celsius to reduce its viscosity. Then, it is injected into the reactor and thermally decomposed at temperatures of 1300-1800 degrees Celsius in order to yield carbon black powder and tail gas.

The carbon black and tail gas mixture are then cooled to a temperature of 250-300 degrees Celsius. The carbon black is separated and filtered through a main bag filter while the tail gas is recycled for use in other process sections, which enables energy and production cost savings. It is then pulverized and formed into pellets for higher density to facilitate product handling. This process is monitored by closed circuit TV to ensure the right size of the carbon black pellets. Next, the pellets are dried in a rotary dryer where recycled tail gas is used as the source of heat. The dried carbon black pellets are moved to a vacuum-sealed conveyor belt system. A vibrating screen is used to regulate pellet sizes, while a rotary magnetic separator removes any impurities before loading into storage tanks. Quality testing is conducted both before and after storage to ensure the right quality of products.

Recognizing the significance of maintaining the highest standards of quality.

TCP applies a quality assurance (QA) system from the initial production stage to the final packaging so that product quality is continually monitored throughout production. Any problems that occur during the production process will be detected early and products that do not meet the required specification will be immediately rejected. Carbon black products from TCP are recognized for their internationally accepted standard. Given the lowest amount of impurity contained in the product, this helps prevent any quality problems that our customers may face during their production process.
