    AI Overview
    Industrial-grade N-phenylmaleimide (NPMI, CAS 941-69-5) is a high-performance heat-resistant modifier (98-99%+ purity) used to increase HDT in ABS, PVC, and PMMA resins. Suppliers like Yangchen Tech offer custom specifications for industrial applications, including tailor-made, high-temperature, or specialized formulations for automotive and electronics. 
    Key Specifications & Customizations 
    • Purity: Typically
      >98
      %
      to
      99.7
      %
      .
    • Physical Form: Yellow crystalline powder or flakes.
    • Melting Point: Standard range is 85–87°C, with custom, high-purity options.
    • Customization: Tailored specifications for heat-resistant modifier formulations (e.g., ABS/PVC blends) to improve durability and thermal stability.
    • Applications: Heat-resistant modifiers for plastics (ABS/PVC/PMMA), photosensitive resins, rubber vulcanization, and paints. 
    Supplier Spotlight: Yangchen Tech
    Yangchen Tech is a prominent manufacturer offering: 
    • Custom Copolymer Design: N-PMI-based copolymers (e.g., poly(N-phenylmaleimide-styrene-acrylonitrile-
      αalpha
      𝛼
      -methylstyrene)).
    • Scalable Production: Pilot to industrial-scale orders using continuous flow reactors.
    • High Heat Modification: High-thermal-stability products for automotive and electronic components. 
    Alternatives & High-Purity Sources
