Matrinox 101 MB
Matrinox 101 MB by Tricon - Precision Crosslinking for Advanced Polymer Performance
Matrinox 101-MB is the trade name for 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane, a high-performance organic peroxide widely used as a polymerization initiator and crosslinking agent. It is primarily applied in polypropylene modification and elastomer processing, where controlled radical generation is required at elevated temperatures. The product is known for its reliable decomposition profile and consistent performance in industrial polymer applications.
In polypropylene processing, Matrinox 101-MB is commonly used for rheology modification, helping manufacturers adjust melt flow index (MFI) to achieve improved processing characteristics. This makes it especially valuable in producing injection-molded and extrusion-grade polypropylene products. In rubber and elastomer industries, it acts as an efficient crosslinking agent, enhancing thermal resistance, elasticity, and mechanical strength.
The “MB” designation typically refers to a masterbatch form, meaning the peroxide is pre-dispersed in a polymer carrier for safer handling and uniform mixing during processing. This form improves dosing accuracy and reduces risks associated with handling pure organic peroxides.
Matrinox 101-MB appears as a colorless to light yellow liquid (or dispersed masterbatch form) and must be stored under controlled conditions to maintain stability. With a flash point around 68°C and density between 0.870–0.875 g/cm³ at 20°C, it requires careful temperature management and proper storage away from heat sources and incompatible materials.
Due to its strong oxidizing nature, it is strictly limited to industrial polymer applications and must be handled with appropriate safety precautions.
Key Types and Characteristics of Matrinox 101 MB
Matrinox 101-MB is available as a liquid organic peroxide and more commonly as a masterbatch (MB) dispersion in a polymer carrier. The masterbatch form enhances safety, improves handling, and ensures uniform distribution during polymer processing. It is supplied in industrial-grade packaging suitable for plastic and rubber manufacturing operations.
Matrinox 101-MB has no approved applications in food or nutritional products. Due to its reactive peroxide chemistry, it is strictly restricted to industrial polymer processing. It is not used as a food additive, preservative, or processing aid and must not come into direct contact with food materials.
Industrial applications include polypropylene rheology modification and elastomer crosslinking. It is widely used in plastic compounding, injection molding, extrusion processes, and synthetic rubber manufacturing. It does not serve as a pharmaceutical ingredient but may indirectly contribute to the production of polymer-based medical device components.
Matrinox 101-MB has no role in animal feed production or formulation. Its oxidative and reactive properties make it unsuitable for feed or nutritional applications. Any relevance is indirect, limited to polymer packaging materials manufactured using peroxide-initiated processing techniques.
Matrinox 101-MB appears as a colorless to pale yellow liquid or dispersed masterbatch. Density ranges between 0.870–0.875 g/cm³ at 20°C, with a flash point around 68°C. It is flammable and may decompose if overheated. Proper storage in cool, ventilated areas away from heat and incompatible substances is essential.
The compound is produced through controlled peroxide synthesis involving tert-butyl hydroperoxide derivatives under catalytic conditions. After formation of the peroxide bond, purification and stabilization steps are carried out. For masterbatch production, the active peroxide is uniformly dispersed in a compatible polymer carrier to improve safety and processing performance.
