Nouryon Brand DirectorIn China, Arkema and Japan Oil are the main producers of TBIC, while other internationally renowned chemical companies such as Unipolymer and Nouryon produce it in overseas factories and import it into China. Nouryon's corresponding product is Trigonox BPIC-C75, which is widely used in industrial production. Due to its excellent performance, particularly in polymerization and curing processes, TBIC has become an indispensable material in the chemical industry.
Basic Information on TBIC
Chemical Name:Tert-Butyl Peroxy Isopropyl Benzene Carbonate
CAS Number:2372-21-6
UN Number: 3103
Main Properties of TBIC
1. Safety Characteristics
TBIC has a flashpoint of 75°C, indicating relatively high safety. However, as a hazardous chemical, TBIC must be stored and transported in compliance with strict safety regulations. Its Self-Accelerating Decomposition Temperature (SADT) is 70°C, and the recommended storage temperature is 25°C, ensuring its stability and efficiency.
2. Active Oxygen Content
TBIC contains an active oxygen content of 6.72%-6.90%, giving it strong initiating power suitable for various industrial polymerization and curing applications. The product is typically supplied in a 75% concentration, dissolved in isododecane solution, ensuring good solubility and safe usage.
Applications of TBIC
1. Acrylic Polymerization
TBIC is widely used as an initiator in the polymerization of acrylic acid and methacrylic acid. It not only improves polymerization efficiency but also significantly enhances the quality of the final product, making it important in fields like coatings and adhesives.
2. Thermoplastic Elastomer (TPV) Processing
TBIC plays a key initiating role in the production of TPVs. These materials are known for their high strength and good flexibility, and are widely used in automotive parts, industrial products, and more. TBIC significantly improves the durability and elasticity of these materials, making it the ideal choice for high-performance elastomer production.
3. Curing of Thermosetting Composites
TBIC is also widely used in the curing process of sheet molding compounds (SMC) and bulk molding compounds (BMC). These thermosetting composites are commonly used in the automotive and construction industries. TBIC does not release benzene-based volatile compounds during the curing process, making it an environmentally friendly option, providing a greener solution for industrial production.
Market Competition
TBIC, being a relatively niche chemical, requires high production and quality control standards, making the industry entry barriers high. Due to the strict technical and safety management required, small chemical factories find it difficult to participate in production. The market is primarily dominated by large chemical enterprises with technical advantages, such as Arkema and Japan Oil. International companies like Nouryon have also secured a foothold in the Chinese market through imports.
Packaging and Transportation
The standard packaging for TBIC is a 30-liter HDPE drum, containing 25 kilograms of product. This packaging complies with international transportation and storage standards, ensuring safe management and use for industrial customers. It guarantees product stability during transportation and storage, while making it easy for customers to access the product as needed.
TBIC, as an efficient peroxide initiator, plays an important role across multiple industry sectors, especially in applications such as acrylic polymerization, TPV processing, and curing of thermosetting composites. With the increasing demand for efficient, safe, and environmentally friendly production, the market demand for TBIC continues to grow. Evergreen Chemicals is committed to providing high-quality TBIC products and offering professional technical support to help customers achieve better results in industrial production.
By understanding the properties, applications, and market situation of TBIC, you can better leverage the potential of this chemical to improve efficiency and quality in production processes, meeting the growing market demand.
