N-Phenylmaleimide, with the CAS number 941 - 69 - 5, is a chemical compound that has gained significant attention in various industries. The product is factory - supplied, which ensures a stable and cost - effective source. It comes at a good price, making it an attractive option for businesses looking to optimize their costs.
Chemically, N - Phenylmaleimide has a molecular formula of C₁₀H₇NO₂. Its molecular weight is approximately 173.16 g/mol. It appears as a white to light yellow crystalline powder. The melting point of N - Phenylmaleimide is around 86 - 89 °C. It has a certain level of solubility in common organic solvents such as acetone, chloroform, and benzene, but has relatively low solubility in water.
2.1 Polymer Industry
N - Phenylmaleimide is widely used in the polymer industry. It can be used as a comonomer in the synthesis of various polymers. By copolymerizing with other monomers, it can improve the heat resistance, mechanical properties, and chemical resistance of polymers. For example, in the production of ABS (Acrylonitrile - Butadiene - Styrene) resins, the addition of N - Phenylmaleimide can enhance the heat - deflection temperature of the resin, making it more suitable for applications in high - temperature environments.
2.2 Rubber Industry
In the rubber industry, N - Phenylmaleimide can be used as a cross - linking agent. It can improve the cross - linking density of rubber, thereby enhancing the mechanical properties, such as tensile strength and tear resistance, of rubber products. It can also improve the heat aging resistance of rubber, extending the service life of rubber products.
2.3 Adhesive Industry
It can be used in the formulation of adhesives. By adjusting the properties of the adhesive matrix, it can improve the adhesion strength and heat resistance of the adhesive, making it more suitable for bonding materials in high - temperature or harsh environments.
3.1 Handling Precautions
When handling N - Phenylmaleimide, it is necessary to wear appropriate protective equipment, including gloves, goggles, and a lab coat. Avoid inhalation of dust and direct contact with skin and eyes. If contact occurs, immediately rinse the affected area with plenty of water and seek medical advice.
3.2 Storage Conditions
The product should be stored in a cool, dry, and well - ventilated place. Keep it away from sources of ignition, heat, and direct sunlight. It should be stored in a tightly closed container to prevent moisture absorption and contamination.
3.3 Usage in Polymerization
In polymerization reactions, the appropriate amount of N - Phenylmaleimide should be added according to the specific formulation requirements. It is usually dissolved in an appropriate organic solvent first and then added to the reaction system. The reaction temperature and time should be strictly controlled to ensure the quality of the polymer product.
4.1 Case 1: ABS Resin Production
A plastics manufacturing company planned to improve the heat resistance of its ABS resin products. They added N - Phenylmaleimide as a comonomer in the polymerization process. By adjusting the dosage of N - Phenylmaleimide, they found that when 5% N - Phenylmaleimide was added, the heat - deflection temperature of the ABS resin increased from 80 °C to 105 °C. This improvement enabled the company's ABS resin products to be used in automotive interior parts that require higher temperature resistance, expanding their market share.
4.2 Case 2: Rubber Sealing Ring Production
A rubber products factory used N - Phenylmaleimide as a cross - linking agent in the production of rubber sealing rings. After using N - Phenylmaleimide, the tensile strength of the sealing rings increased by 20%, and the tear resistance also improved significantly. In addition, the heat aging resistance of the sealing rings was enhanced, reducing the replacement frequency in high - temperature environments and saving costs for customers.
