The New Kremeon PPS from Kureha Corp. is not the kind of material you notice at first glance, yet it sits behind the clean click of a connector or the quiet glide of a small pump rotor. Touch a molded PPS housing and you feel a tidy, almost waxy surface that stays rigid even after a long day next to hot electronics.
Where New Kremeon PPS fits
Kureha positions New Kremeon PPS as a polyphenylene sulfide resin for parts that need to stay dimensionally stable when the heat goes up and moisture swings around. In practice that means connector blocks, precision gears, pump bodies and valve components where a warped millimeter can ruin a whole assembly.
In automotive and industrial settings, engineers reach for PPS when standard engineering plastics like PA6 or PBT creep or absorb too much water in long service. A Kremeon PPS connector in an engine bay, for example, has to keep its pin alignment under high temperature and exposure to fluids without swelling or embrittling over time.
How the material behaves
New Kremeon PPS belongs to a family of semi-crystalline, high-heat polymers that retain stiffness well above 200 degrees Celsius, which makes them suitable for parts near power electronics and under-hood components. The polymer’s backbone resists most fuels, oils and many solvents, so an injection-molded Kremeon PPS pump housing can sit in contact with aggressive media without softening.
Compared with commodity plastics, PPS typically shows low water absorption and good dimensional stability, which translates into tight tolerances in gear wheels and actuator housings. In molding shops, technicians value the material for its ability to reproduce fine details, although they have to manage higher melt temperatures and, often, more abrasive fillers that can wear screws and barrels faster.
Background on Kureha shares
Kureha’s specialty materials such as New Kremeon PPS feed into automotive and electronics supply chains and form a quiet backbone for the company’s listed business in Tokyo.
What engineers and buyers notice
When a buyer at an automotive supplier runs fingers over sample plaques, New Kremeon PPS feels rigid and self-assured, with a smooth surface that suggests clean mold flow. That matters for connector housings that must accept seals and gaskets without rough spots that could leak or snag during assembly.
Mechanical designers look at data sheets and see PPS grades offering high tensile strength and modulus, especially when reinforced with glass fiber or mineral filler. That lets them slim down wall thickness and save weight while maintaining stiffness, a quiet advantage in applications such as electric vehicle battery modules where every gram and every cubic millimeter counts.
Design freedom and limits
New Kremeon PPS gives molders freedom to design thin ribs and complex gating systems, but the high melt temperature demands careful process control and robust tooling. In practice, toolmakers have to specify steels and surface treatments that stand up to hot, sometimes filled resin over long production runs.
On the downside, PPS in general can be more brittle than some aliphatic engineering plastics, so parts that expect high impact loads need thoughtful design with radiused corners and controlled notch effects. For snap-fit features in housings, designers often simulate stresses to avoid cracks during assembly or service.
How it plays in Kureha’s portfolio
Under president and CEO Kiyoshi Tanimura, Kureha has leaned into specialty chemicals and advanced materials that tuck inside larger systems rather than chase mass-market consumer branding. New Kremeon PPS fits that strategy by quietly serving as a base material for customers’ components in automotive, industrial and electrical markets.
Alongside PPS, Kureha develops materials such as carbon products and advanced resins that target similar high-performance niches. For a tier-one supplier, being able to source PPS from a company that also understands composite design and processing can simplify long-term platform planning and qualification.
Stock and business context
New Kremeon PPS does not move the ticker on its own, but it underpins recurring business with automotive and electronics clients that care more about long-term stability than a single quarter’s buzz. Overall, Kureha shares (ISIN JP3313200001) are listed on the Tokyo Stock Exchange in Japanese yen, where investors track the company as a specialty materials name.
