N-Phenylmaleimide (N-PMI) manufactured by Yangchen Tech is a high-performance specialty monomer widely used in polymer modification, particularly in heat-resistant plastic formulations. With its unique structure and superior thermal properties, N-PMI is becoming a crucial additive in various industries such as automotive, electronics, and advanced materials.

Basic Information

Key Properties of N-Phenylmaleimide

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.
