In the vast world of chemistry, N-Phenylmaleimide (NPMI) stands out as a remarkable compound due to its diverse applications and unique properties. With its purity level reaching 99%, NPMI manufactured by Yangchen Tech has proven to be an invaluable addition to various industries, particularly as a heat-resistant modifier in resins such as ABS, PVC, photosensitive materials, and PMMA.     Chemical Structure Chemical Formula C10H7NO2 Molecular Weight 173.16 CAS No. 941-69-5 Packing Type Paper bag (20 kg)       Improving Resin Properties When used as a heat-resistant modifier in resins like ABS, PVC, photosensitive materials, and PMMA, NPMI significantly enhances the overall performance of these materials. By embedding NPMI into the polymer chains, it increases the internal rotational resistance of the chains, thereby improving the heat resistance of the resin. The addition of just 1% NPMI as a comonomer to ABS can increase the heat distortion temperature by 2°C. This seemingly small increase can make a significant difference in the performance of the resin, especially in applications where high temperatures are encountered. Moreover, when 10% NPMI is mixed with ABS, the heat-resistant temperature can reach 125-130°C. This remarkable improvement in heat resistance makes ABS resins modified with NPMI suitable for a wide range of applications that require high thermal stability.   Specification     Property Limits Results Appearance Yellow crystalline powder Yellow crystalline powder Purity % >98 99.5 Melting Range ℃ >85 88~90     Other Benefits of NPMI In addition to improving heat resistance, NPMI also enhances the impact resistance, hotmeltability, and processability of the resin.

  Unlocking the highest performance of engineering plastics with advanced thermal stabilization technology   Exploring Heat-Resistant ABS Acrylonitrile-butadiene-styrene copolymer (ABS) is a widely used engineering plastic, prized for its exceptional toughness, rigidity, and ease of processing. However, standard ABS suffers from a significant limitation: its heat deflection temperature (HDT), typically ranging from 85°C to 95°C, restricting its use in high-temperature applications such as automotive parts, electronic housings, and industrial equipment. To overcome this shortcoming, manufacturers are constantly searching for effective thermal modifiers that balance performance, cost, and processing efficiency. Among these solutions, N-phenylmaleimide (N-PMI) has emerged as a leading additive for thermal enhancement of ABS. This article will explore the science behind N-PMI's effectiveness, aiming to provide high-performance N-PMI solutions for industries worldwide.   N-phenylmaleimide   N-phenylmaleimide   ABS Heat Resistant agent modifier       1. The Science Behind N-PMI: How It Improves ABS's Heat Resistance N-PMI is a rigid cyclic monomer with a molecular structure consisting of 1,2-disubstituted vinyl groups embedded in a five-membered ring. When copolymerized with ABS or blended as an additive, it acts as a "molecular scaffold," restricting the mobility of the polymer chains. This restriction raises the glass transition temperature (Tg) of ABS, directly improving its heat resistance without compromising its mechanical integrity. Key mechanisms include: - Enhanced Chain Rigidity: The phenyl and imide groups in N-PMI introduce steric hindrance, reducing chain rotation and improving thermal stability. - Synergistic Copolymerization: N-PMI binds to the ABS polymer during the synthesis process, forming covalent bonds that stabilize the matrix and prevent thermal degradation. Research has shown that adding 10% N-PMI to ABS can produce ultra-high-heat-resistant ABS with an HDT of 125-130°C, a 30-40°C improvement over unmodified ABS.   2. Why N-PMI Outperforms Other Thermal Modifiers While other additives (such as glass fiber, mineral fillers, or other imides) can improve heat resistance, they often sacrifice processability, impact strength, or surface finish. N-PMI offers the following unique advantages: - Balanced Performance: It simultaneously enhances heat resistance, tensile strength, and melt processing. - Low-Dosage Efficiency: Even a 1% addition can increase the HDT by 2°C, enabling precise calibration for cost-sensitive applications. - Compatibility with Additives: N-PMI works synergistically with stabilizers, pigments, and flame retardants, making it an ideal choice for multifunctional composites. In contrast, fillers such as talc or silica can reduce toughness, while other thermal stabilizers typically require higher addition levels, increasing viscosity and complicating processing.   Basic Information   Property Description Chemical Name N-Phenylmaleimide Synonyms NPMI, Monomaleimide CAS Number 941-69-5 Purity ≥99% Appearance Pale yellow crystalline powder Manufacturer Shaanxi Yangchen New Material Technology Co., Ltd   Key Properties of N-Phenylmaleimide   Property Description                                                          Thermal Stability  Decomposition temp. >300°C Glass Transition Temp.
