NISSEI CORPORATION Product Lineup

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.

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.

This is a transparent pipe made from materials compliant with the Japanese Food Sanitation Act and the U.S. FDA, allowing visibility inside the piping. It features high chemical resistance, heat resistance, hot water resistance, and mechanical strength. It can withstand over 1,000 cycles of steam sterilization, and we have successfully achieved the extrusion molding of thick-walled pipes with a thickness of over 10mm using the high-performance plastic "PPSU," a first in Japan. It can be used in areas where stainless steel piping cannot be employed, such as in metal detection. Depending on the usage environment, it can also replace fluoropolymer resins, leading to cost reduction. *For more details, please download the PDF or contact us.
