- Superior TPE Material for Demanding Applications
We use premium Thermoplastic Elastomer (TPE) for its unique combination of properties:
Exceptional Safety: Our TPE compound is rigorously tested and complies with the UL 94 V-0 flame retardancy standard. This highest rating ensures maximum safety for sensitive applications in data centers, enterprise networks, and industrial settings.
Durability & Flexibility: TPE offers excellent elasticity, tear resistance, and longevity. Our boots provide superior strain relief, withstand repeated mating cycles, and resist cracking, ensuring lasting protection for the fiber.
Environmental Resistance: The material is formulated to perform reliably across a wide temperature range and resist exposure to chemicals, UV light, and moisture.

- Custom Mold Design & Engineering
The perfect boot starts with a perfect mold. Our in-house mold design and fabrication capabilities allow for:
Full Customization: We tailor boots to your exact specifications—interface type (LC, SC, MPO, etc.), locking mechanism, cable entry style, and branding.
Precision Engineering: Our molds are built for high-precision, flash-free manufacturing, ensuring consistent dimensions, perfect fit, and excellent sealing with your connector assembly.
Rapid Prototyping: We accelerate your development cycle with quick turnaround on prototypes, getting you from concept to sample faster.
- High-Volume, Quality-Driven Production
Our manufacturing process is built for quality and scale:
Automated Injection Molding: We utilize advanced, fully automated injection molding systems to produce large volumes with unmatched consistency and efficiency.
Stringent Quality Control: Every production run is supported by rigorous process controls and 100% inline inspection to guarantee every boot meets our exacting standards for dimensions and appearance.
