Achieve precise braking response and repeatable stopping performance.
STARLITE’s proprietary friction-material formulations.
STARLITE pioneered resin-molded winder brakes for papermaking machinery in the late 1950s, helping enable stable operation, higher line speeds, and improved productivity.
We have continuously developed friction materials for demanding conditions such as:
• high loads
• continuous sliding contact
• reduced wear of the metal counterface while also achieving long service life.
- In response to ESG and carbon-neutral initiatives, we are expanding friction materials based on biomass-derived resins to reduce dependence on petroleum-based feedstocks.

They offer high heat resistance, excellent wear resistance, and strong fade resistance, helping maintain braking performance even under continuous duty.
They are also effective in reducing noise and squeal.
- #18850 (Standard): Designed for smooth, mild engagement, helping reduce shock to equipment while delivering stable torque performance.
- #18855 (High-performance at elevated temperature): Maintains stable torque even as temperature rises; a high braking-force grade.
- #86140 (High torque / low wear): Provides high torque with excellent low-wear performance.
Injection-Molded Friction Materials for Controlled Slip
- Material selection to match your needs—choose grades optimized for holding or braking requirements.
- High-volume manufacturing with S-BEAR injection-molded materials. We also support insert molding, enabling part consolidation and reduced part count.
- Available in thermoplastics, thermosets, and biomass-based materials.
- Exceptionally high flexural strength. Compared with off-the-shelf engineering plastics, these materials can meet application requirements without metal reinforcement in many cases, enabling weight reduction and quieter operation.
- High heat and wear resistance, with a stable coefficient of friction even under temperature changes.
Equipment-friendly. Planet-friendly.
Biomass-Based Resin Friction Materials
X2101 is a newly developed brake friction material that shows minimal variation in friction and wear performance as temperature changes, compared with conventional grades based on fossil-derived resins.This stability supports quiet operation and consistent holding torque and braking torque, making it a strong candidate for power-off (fail-safe) brakes used for holding and emergency stopping in collaborative robots (cobots)—a need expected to grow from large-scale factories to smaller workplaces.
