(Tg) Significantly increases Tg of ABS and other resins Compatibility Compatible with styrenics (e.g. ABS, SAN), epoxy resins, and engineering plastics Solubility Dissolves in acetone, DMF, THF, etc.     Applications of N-Phenylmaleimide   1. Heat-Resistant Modifier for ABS and Other Plastics   N-PMI significantly improves the heat distortion temperature (HDT) of ABS (Acrylonitrile-Butadiene-Styrene) by increasing rigidity and thermal resistance without sacrificing impact strength. Ideal for automotive interiors, electronics housings, and appliance parts.   2. Monomer for High-Performance Polymers   It acts as a reactive monomer in polymerizations for polyimides, bismaleimides, and copolymers, enhancing thermal, chemical, and oxidative resistance.   3. Crosslinking Agent   Due to its maleimide functionality, NPMI enables crosslinking in styrenic and vinyl polymers, leading to stronger, more heat-stable network structures.   4. Electronics & Semiconductor Materials   Used in resin systems for encapsulants, prepregs, and adhesives where high heat resistance, dimensional stability, and low dielectric loss are critical.   5. Coatings and Adhesives   NPMI enhances adhesion strength and thermal stability in advanced coatings and industrial adhesives.     Why Choose Yangchen Tech’s N-Phenylmaleimide?   As a leading Chinese manufacturer and exporter, Yangchen Tech offers:   High-purity NPMI (≥99%) Flexible packaging and OEM services Global shipping and technical support Customization for research or industrial scale   We focus on quality, consistency, and customer-specific formulations, making our N-PMI ideal for global markets across automotive, aerospace, electronics, and materials science.    👉 Learn more or request a sample at https://www.yangchentech.com     Frequently Asked Questions (FAQ)   Q1: Is N-Phenylmaleimide safe to use?

When purchasing N-phenylmaleimide, buyers must pay attention to several key factors to ensure you are getting a high-quality product that meets your requirements:   Purity: Check the purity level of the supplied N-phenylmaleimide. Higher purity ensures better performance and fewer impurities that could affect downstream reactions or product quality.   Quality Control Standards: Ensure that manufacturers follow strict quality control standards and procedures to maintain product consistency and reliability. Look for certifications or compliance with industry standards.   Packaging: Verify that product packaging is appropriate to prevent contamination or degradation during storage and transportation. Properly sealed containers and appropriate labeling help maintain product integrity.   Handling and Storage Guidelines: Know the recommended handling and storage conditions for N-phenylmaleimide to avoid degradation or loss of potency. Temperature, humidity and light all affect its stability.   Supplier Reputation: Choose a reputable supplier with a proven track record of delivering high-quality chemicals and providing excellent customer service. Customer reviews and references can provide valuable insights into a supplier's reliability.   Safety Data Sheet (SDS): Ask your supplier for the Safety Data Sheet for N-phenylmaleimide to understand its hazards, safe handling procedures, and emergency response measures. Complying with safety regulations is critical when handling hazardous chemicals.   Batch consistency: Query the consistency between batches to ensure the consistency of product quality and performance. Consistent quality is especially important for processes that require precise control of reaction conditions.   Technical Support: Evaluate the level of technical support provided by the vendor, especially if you need help with product selection, troubleshooting, or application-specific advice.   N-Phenylmaleimide 97% N-PMI (ABS heat-resistant agent) manufactured by Yangchen Tech is used as a heat-resistant modifier in ABS, PVC, PMMA resins and photosensitive materials to improve the heat resistance, impact resistance, and hot melt resistance of the resin properties and processability, etc. When NPMI is added as a comonomer to ABS, the heat distortion temperature can be increased by 2°C; when 10% of NPMI is blended with ABS, the heat-resistant temperature can reach 125-130°C.
