N-PMI (N-Phenylmaleimide) is a high-performance chemical intermediate that can be used for a variety of applications and is a must-have product for many industries. Finding a reliable N-PMI supplier is a challenging task as the market is vast and there are many factors to consider. The following three points will help you:
1. How to choose an N-PMI Manufacturer
When looking for a reliable N-PMI supplier, it is critical to ensure that the supplier you choose is an N-PMI manufacturer. Manufacturers produce N-PMI from the ground up, ensuring product quality, consistency, and reliability. Working directly with a manufacturer offers several advantages, including better lines of communication, faster delivery, and lower prices.
2. Evaluate Supplier Production Capabilities
To ensure a sustainable supply of N-PMI, you need to select a supplier with good manufacturing capabilities. It is important to check whether the supplier has advanced equipment and technology. You should also find out their production scale to ensure that they are capable of meeting your volume requirements. A supplier with excellent production capacity can provide high-quality N-PMI products in a timely and consistent manner.
3. Checking Certifications
Verifying certification is an essential step in finding a reliable N-PMI supplier. Certification is proof that a supplier adheres to international standards. In particular, you should look for the Reach certification, which ensures that a product complies with European Union regulations regarding the registration, evaluation, authorization, and restriction of chemicals. In addition, you should verify that the supplier has obtained the IS09001-2015 international quality system certification as well as environmental and occupational certifications. These certifications ensure that the supplier complies with environmental and quality standards.
In addition to these three points, it is important to check the supplier’s communication skills, delivery capabilities, and after-sales service. A reliable supplier should be responsive, flexible, and committed to providing excellent customer service.

N-phenylmaleimide produced by Yangchen Technology can be used in antifouling of marine warships.The specification is greater than 98%.
Initially, modified acrylic resin (PAZ/ N-PMI). Composite coating samples were prepared by dispersing fluorinated silica-coated hydroxylated multi-walled carbon nanotube nanocomposites (F-MWCNTs-OH@SiO2) in PAZ/N-PMI resin. The composite coating showed good performance, and the antibacterial rate of the composite coating against Staphylococcus aureus and Escherichia coli was >99.98%. When the F-MWCNTs-OH@SiO2 content is 3 wt%, the Zf=0.01Hz of the composite coating reaches the highest value, which is 3 orders of magnitude higher than that of the PAZ/N-PMI coating. At the same time, the prepared composite coating also showed good self-healing properties. This research provides broad application prospects for the development of high-quality marine anti-corrosion and anti-fouling organic coatings.
Acrylic resin coatings play an important role in metal protection due to their low cost, safety, environmental protection, and good weather resistance. However, its poor thermal stability and weak antifouling performance greatly limit its practical application in engineering. However, the metal structures of marine ships and various coastal steel structure engineering equipment have been exposed to complex and harsh marine environments (high salt spray, humidity, strong winds) for a long time. Therefore, corrosive media and external stress will damage the coating surface, causing the coating to crack and fall off. Therefore, the corrosive medium is more likely to penetrate into the coating and reach the metal matrix, causing the protective function of the coating to fail. Therefore, the self-healing function is very important for protective coatings because it can repair damaged parts, extend the protective life, and reduce the maintenance cost of the coating. However, there are few reports on the use of self-healing coatings for marine anticorrosion and antifouling.
Research has demonstrated that embedding bactericidal functional groups into polymers can effectively inhibit microbial adhesion, making it a significant development for antifouling applications. N-phenylmaleimide (N-PMI) has become a hot topic in polymer material modification research due to its good thermal stability, good antibacterial properties, and no environmental pollution. From a structural point of view, N-phenylmaleimide (N-PMI) is a five-membered ring monomer with a 1,2-disublimate vinyl structure. N-PMI can react with acrylic monomers to form polymers. N-PMI is also a heat-resistant polymerizing monomer. Embedding it into the polymer chain can increase the internal ring resistance of the polymer chain, limit the movement of the polymer molecular chain, and improve the thermal stability of acrylic resin. N-PMI has extensive antibacterial activity against microorganisms such as Escherichia coli and Staphylococcus aureus, and can effectively inhibit the reproduction and growth of microorganisms for a long time.
This new acrylic composite coating will effectively reduce marine corrosive media and marine fouling biomass on marine ships and engineering equipment, and increase their service life.
