Functional Range
Slide. Brake & Hold.
Transmit. Seal.
Supporting reliable motion
in machines.
Bearings (Slide) that control the coefficient of friction (CoF) and minimize wear. Friction materials (Stop) that deliver reliable braking and holding performance. Polymer gears (Transmit) that transfer power efficiently. Sealing products (Seal) that prevent leakage while reducing damage to the counterface. Across these functions, we help improve the reliability of machines and equipment.
Application Range
A proven track record across industries—from social infrastructure to
cutting-edge robots.
Our products have been adopted across a wide range of industries—from large-scale equipment in steelmaking and papermaking to transportation systems such as rail, marine, and automotive, as well as office equipment and robotics. This breadth reflects the strength of our technical foundation.
Temperature Range
Stable Performance From -200°C Cryogenic to 800°C High-Temperature Environments
We maintain stable performance even in extreme environments—from the high-temperature zones of steel rolling processes to cryogenic conditions at liquid-hydrogen temperatures. For operating conditions that are challenging for conventional materials, we combine material engineering with upfront simulation and testing to define the optimal specifications.
Lubrication Range
Optimized for your conditions—from water- and oil-lubricated environments to fully dry-running operation.
Even in environments where lubricants can’t be used—and under harsh conditions where seawater, chemicals, or slurry may enter—we maintain smooth motion and high wear resistance. Across a wide range of operating environments, we support reliable, long-lasting performance you can count on.
Material Range
Proprietary Formulation Technology Adds Multiple Functions to Materials
BAKES is based on thermoset resins. ALP is based on fluoropolymers. S-BEAR consists of our injection-moldable high-performance materials. Each is engineered with proprietary combinations of reinforcements and fillers, including organic and inorganic fibers. By designing the material itself from the ground up, we turn the optimal concept into a working product.
Process Range
Matched Processes for Each Material and Product—Compression, Extrusion and Injection
We select the optimal manufacturing route to match material behavior and required specifications—from laminated, heat-pressed fiber composites for plates and tubes to compression/extrusion with machining, and injection molding options such as insert molding and gas-assisted injection molding.
Geometry Range
From Millimeter-Scale Parts to Meter-Class Components—and Seamless Lengths Over 100 m
From small precision parts requiring fine tolerances to seamless long-length products and meter-class large, thick-section components, we deliver the specifications you need with minimal constraints on size or geometry. We can also design not only individual parts but complete assemblies—units that incorporate surrounding mechanisms as an integrated system.
Validation Range
From CAE Prediction to Real-World Testing—Recommendations Backed by Evidence
We use CAE simulation upfront to identify the optimal solution, then confirm performance through testing with our in-house evaluation equipment. Our product reliability is built on this cycle of prediction and validation.
Starlite Core Tech
Starlite’s core technology is connecting polymer material development with geometry design and manufacturing optimized for those material properties
—and then validating performance to bring the optimal solution to life.
Analysis (CAE)
Leveraging our extensive accumulated data, we perform upfront verification from flow simulation to structural analysis. This helps reduce prototype iterations and rework, keeping development moving smoothly and efficiently.
Verification
With our in-house evaluation facilities, we can test under a wide range of conditions. For example, we measure wear and coefficient of friction (CoF) to verify performance against your target requirements.
Molding & Tooling Engineering
For materials that are difficult to mold, we have established mold design and manufacturing processes to achieve the intended geometry and precision. We reflect simulation results in tooling design to enable high-accuracy, repeatable molding.
Production System
We support everything from one-off prototypes to mass production at volumes of hundreds of thousands of parts per month. By coordinating our manufacturing sites in Japan and overseas, we maintain required quality and ensure stable supply.
Materials Design
We design material combinations and formulations to match operating conditions such as temperature, load, and counterface material. By engineering materials to meet target performance, we translate required properties into real, usable functions.
Geometry & Unit Design
We design product geometry to fully leverage material performance—and can extend to unit-level design that includes surrounding mechanisms. By maximizing the use of field experience and simulation, we propose the optimal geometry for each application.

Materials Development
Advancing Chemical Recycling
Phenolic resins have long been considered difficult to recycle. In a joint research project with the University of Fukui, STARLITE is exploring a technology that introduces a special acetal linkage into the resin structure, aiming to enable chemical depolymerization and open a path toward circular use.
Controlling Friction with Plant-Based Materials
STARLITE is developing friction materials that use biomass-derived raw materials, with the goal of moving away from petroleum-based inputs. By overcoming challenges in cost and material performance, we aim to commercialize these as next-generation materials with a lower environmental footprint.
Responsible Manufacturing
Turning Production Scrap into Resources
In the production of our mass-produced fluoropolymer products, offcuts and scrap are generated during processing. Instead of discarding them, we grind and reuse the material. By developing our proprietary ram extrusion process, we aim to build a system where production scrap is recovered and reborn as usable product material.
Reducing Plastics in Packaging
We are gradually replacing disposable plastic cushioning and packaging materials used for shipping with reused cardboard, including material recovered from waste corrugated boxes. This step helps reduce single-use plastics and supports more sustainable logistics.
