Melgran Series Products:
• Melgran CBS 80: Chemically known as N-cyclohexyl-2-benzothiazole sulfenamide, it is a rubber accelerator used in the vulcanization process. It is particularly widely used in the production of rubber products. The active content of CBS is 80%, and the remaining 20% consists of dispersing agent or carrier material. It provides a slow start but accelerates later in the curing response. This allows you to efficiently control the vulcanization process. It is compatible with many types of synthetic rubber as well as natural rubber. This versatility makes it useful in various applications. When used at optimal levels, it is an effective accelerator and improves the physical and mechanical properties of the final product. It provides good "scorch safety," meaning the cross-linking process does not start prematurely in an undesirable manner, which facilitates the process and reduces manufacturing errors. It is commonly involved in the production of tires, automotive seals, hoses, shoe soles, and other rubber products. The amount in the content should be adjusted according to the needs of the rubber compound, as excessive use can significantly shorten the curing time and lead to unwanted properties.
• Melgran MBT 80: Chemically known as 2-Mercaptobenzothiazole, it is another important vulcanization accelerator used in the rubber industry. The active content of MBT 80 is 80%, and the remaining 20% consists of dispersing agent or carrier material. It is commonly preferred to both activate the vulcanization process and enhance the properties of the final products. By accelerating the vulcanization process, it increases the elasticity and durability of rubber compounds. It can be made more effective when used together with other accelerators. It helps improve the mechanical properties of rubber products, especially tensile strength, flexibility, and aging resistance. It is compatible with natural rubber and some types of synthetic rubber. It is used in the production of automotive tires, shoe soles, hoses, seals, and many other rubber products. When used alone, it has a slightly slower thermal response, but this can be beneficial for process control and safety. It can generally be combined with other sulfenamide accelerators like TBBS or CBS to achieve a more balanced process. It also offers antioxidant properties for rubber products, which can increase the product's resistance to weather conditions, ozone, and other environmental factors.
• Melgran MBTS 80: Chemically known as 2,2'-Dithiobis(benzothiazole), it is one of the commonly used vulcanization accelerators in the rubber industry. MBTS is used to provide a more controlled and slower vulcanization process in rubber compounds. The active content of MBTS is 80%, and the remaining 20% consists of dispersing agent or carrier material. It accelerates the vulcanization process when processed with rubber sulfur. This gives the rubber the necessary elasticity and durability. It is a relatively slow-acting accelerator. It offers advantages in applications where the vulcanization needs to proceed in a controlled manner, which is particularly important in the production of large and thick rubber parts. It can generally be used alone, but is typically used in combination with sulfur-based accelerators like TMTD (Tetramethylthiuram disulfide) for faster and more effective results. It is compatible with both natural and synthetic rubbers. It is widely used in various rubber products such as tires, seals, and shoes, and hoses. The use of MBTS 80 particularly enhances the aging resistance of rubber materials. It offers better protection against ozone and weather conditions with a low level of sulfur requirement. It is not a nitrosamine-forming accelerator, making it a safer choice from an environmental and health perspective, minimizing many by-products. It is a preferred and effective chemical when a slow and controlled vulcanization process is needed in rubber production processes.
• Melgran TMTD 80: Chemically known as Tetramethylthiuram disulfide, it is a frequently used vulcanization accelerator in the rubber industry. It accelerates the vulcanization process involving sulfur, providing the necessary flexibility and strength to rubbers. The active content of TMTD is 80%, and the remaining 20% consists of dispersing agent or carrier material. It ensures a fast vulcanization process in rubber mixtures. It can be used directly or in combination with other accelerators. It is one of the ultra-accelerators that are effective even at very low levels. It is usually used alongside other medium-speed or slow accelerators. TMTD 80 can be used as a "sulfur-free" vulcanization agent, which is particularly preferred in sensitive applications such as autogenous vulcanization processes, medical purposes, and sanitary products. It is generally used in combination with other accelerators like MBTS to control the vulcanization speed; it is preferred especially in applications that require rapid vulcanization. It is used in the production of tires, shoes, hoses, seals, and many rubber-based products. It is an important chemical used to provide a fast and effective vulcanization process in the rubber industry. It is frequently preferred due to its rapid curing properties and low usage levels in the production of rubber materials. However, careful monitoring and control of potential by-products and secondary effects that arise during use is crucial.
• ZDEC-80: Chemically known as Zinc Diethyl-dithiocarbamate, it is a commonly used vulcanization accelerator in the rubber industry. The active content of ZDEC is 80%, and the remaining 20% consists of dispersing agent or carrier material. It acts as an agent that accelerates rubber vulcanization. It provides fast curing even at lower temperatures in rubber mixtures. It stands out for having lower toxicity compared to other dithiocarbamate accelerators, which is why it is preferred in some medical rubber products. It is generally used in latex mixtures, foam rubber, glove production, and many general rubber product manufacturing processes. It optimizes the product's flexibility, durability, and overall physical properties. It is often used in combination with other accelerators, which allows for greater control and speed of vulcanization. It is also frequently used in industrial products like inner tire tubes, hoses, and general-purpose applications. The zinc it contains positively contributes to the vulcanization process. It is especially suitable for applications requiring vulcanization at low temperatures.
• ZBDC-80: Chemically known as Zinc Dibutyl-dithiocarbamate, it is another vulcanization accelerator used in the rubber industry. The active content of ZDBC is 80%, and the remaining 20% consists of dispersing agent or carrier material. It is a substance that accelerates the vulcanization process in rubber mixtures. It is used in direct vulcanization systems and increases productivity by shortening the curing time. It is a suitable accelerator for latex-based products. It is widely used in the production of rubber gloves, balloons, and other latex products. It improves physical properties such as elasticity, durability, and mechanical performance of rubber. It is suitable for applications requiring vulcanization at low temperatures since it is effective even at low temperatures. It is typically used in combination with other accelerators. For example, it can be combined with second accelerators like MBTS, TMTD to create a vulcanization process that can be better controlled. It is used in foam rubber, sealing rings, hoses, and general sealing products. It provides a fast and efficient vulcanization in the production of latex-based products, thus increasing productivity and contributing to the quality of the obtained rubber products.
