NISSEI CORPORATION List of Products and Services

The compatibilizer "Kayaburid" is a maleic anhydride modified polypropylene (MAPP) with a high molecular weight and high grafting rate (high modification rate) compared to conventional products. <Applications> This product is used for the compatibilization of polar substances such as wood flour, CNF, glass fibers, carbon fibers, etc., with olefin-based resins like polypropylene (PP). Additionally, MAPP can be utilized in various fields, including adhesive layers for multilayer films, primers, hot melt adhesives, and more. <Features> Traditionally, molecular weight and grafting rate are in a trade-off relationship, but Kayaburid maintains high values for both due to its special manufacturing process. This allows for the formation of chemical bonds at the interface and the entanglement effect of molecular chains, which can enhance the strength of fillers and improve physical properties.

<Applications> In the industry of recycled resins that expand their use, the reduction of strength and flexibility due to the mixing of dissimilar materials often poses problems when using recycled products. In solving these issues, compatibilizers can be highly effective. 1. Alloying of resins with different polarities 2. Compatibilization of olefin resins with foreign substances (polar) 3. Compatibilization for reinforcement through filler (additive) addition <Features> Originally, molecular weight and grafting rate have a trade-off relationship, but Kayaburid maintains high values for both due to its special manufacturing process. This enables the formation of chemical bonds at the interface and the entanglement effect of molecular chains, which can enhance the strength of fillers and improve physical properties.

We offer coloring for super engineering plastics. We can accommodate everything from prototypes to mass production and will color to your desired color. Mass production is accepted from a minimum order quantity of 25 kg. Please feel free to consult us for new color matching and coloring, as well as for BCP.

Polyether sulfone (PES) with high heat resistance and stable electrical resistance Polyether sulfone is widely used as a high-performance plastic with excellent heat resistance and mechanical strength. By adding additives, we have successfully developed PES that also possesses stable surface resistance. 1. **Heat Resistance**: PES can maintain its shape and performance even in high-temperature environments, capable of withstanding temperatures above 200°C. 2. **Electrical Resistance**: Surface resistance is controlled between 10⁶ and 10¹², preventing the generation of static electricity and the adhesion of dust. 3. **Chemical Stability**: It shows high resistance to acids, alkalis, and oils, remaining stable against chemical agents. 4. **Mechanical Strength**: It has high tensile strength and impact strength, demonstrating excellent durability.

PSU (Polysulfone) High heat resistance Excellent dimensional stability Moderate resistance to acids and bases Excellent moldability Balanced control of oxygen and moisture permeability PES (Polyether sulfone) High heat resistance Chemical resistance to acids, alkalis, and oxidizing agents High mechanical strength and rigidity Excellent film-forming ability and solvent resistance PSU (Polyphenylsulfone) High heat resistance Chemical resistance to acids, alkalis, and oxidizing agents Outstanding hydrolysis resistance and impact resistance Repeatedly suitable for steam sterilization and autoclaving

Product Overview This product is a high-performance thermoplastic compound that combines polyethersulfone (PSf), which has excellent heat and chemical resistance, with carbon fibers in a highly dispersed manner. It exhibits superior rigidity, dimensional stability, and mechanical strength due to the carbon fibers, making it suitable for a wide range of applications including precision instruments, automotive parts, and electrical and electronic components as a metal or PEEK alternative. Features - High Heat Resistance Based on polyethersulfone with a glass transition temperature of 220°C, it maintains its properties even in high-temperature environments. It is also promising as a PEEK alternative. - High Rigidity and Strength The incorporation of carbon fibers achieves mechanical properties capable of handling high-load components and structures. - Excellent Dimensional Stability It has minimal expansion and contraction due to temperature and humidity changes, making it ideal for precision and fitting parts. - Chemical Resistance It has high resistance to acids, alkalis, and organic solvents, demonstrating performance even in harsh usage environments. - Molding Processability It can be injection molded, achieving lower costs and higher productivity compared to PEEK.

The Eco-Promote series is a PLA (polylactic acid) additive that promotes the crystallization of PLA molecules, which are a type of bioplastic. It offers two grades: "Eco-Promote," which significantly shortens molding time, and "Eco-Promote-TF," which maintains transparency after crystallization. By adding these to PLA resin and molding, the heat resistance, productivity, and transparency of PLA products can be improved, thereby expanding their application scenarios.
