UHMWPE Braid
Braided from 100% UHMWPE (Ultra-High Molecular Weight Polyethylene) fiber — commonly known by brand names like Spectra® or Dyneema® — Rocket-Fibers UHMWPE Braided Line delivers an exceptional combination of lightweight performance, extreme strength, and abrasion resistance. This continuous braided line is engineered to excel in demanding applications where strength-to-weight ratio, durability, and reliability matter most.
Our UHMWPE Braided Line is offered in a range of breaking strengths, diameters, and lengths. Custom lengths are available upon request. Bulk quantities are offered for commercial use, with additional processing options — custom coating and winding—available as needed. Each product is conveniently wound on a plastic reel for easy handling and processing, and batch-specific certifications are included with every order to verify authenticity and performance.

UHMWPE Braid Product Details
- 100% UHMWPE fiber braided construction for maximum strength-to-weight performance.
- Continuous braided line with no splices — one continuous length per reel.
- Solution dyed fibers guarantees no color bleeding.
- Available in multiple break strengths and diameters to suit diverse applications.
- Custom lengths and bulk quantities available on request.
Product Performance
- Excellent strength-to-weight ratio makes this braid ideal for applications demanding high load capacity without added weight.
- Good abrasion resistance extends service life in rugged conditions.
- Hydrophobic properties make this braid ideal for outdoor and marine applications where the braided line will not absorb moisture
- UV resistance allows this braided line to be used in applications where other high-performance fibers cannot.
UHMWPE Resistance Guide
UHMWPE fibers like Spectra® or Dyneema® offer high resistance to corrosive substances, such as most acids, alkalis, and organic solvents, making them valuable in industrial settings where chemical exposure is commonplace. However, UHMWPE fibers are not without their shortcomings. They exhibit limited thermal stability, which reduces their performance and longevity at elevated temperatures. While their melting point is approximately 135-147°C, they begin to lose their properties around 100°C. Moreover, UHMWPE fibers possess low flame resistance. In a fire or high-heat scenario, they readily melt and burn.
This fiber exhibits poor flame resistance and will melt at 135°C. It is not advisable to use in any application where an open flame is present.
This fiber exhibits poor heat resistance and will melt at 140°C. It is not advisable to use in any application where high heat is present.
Acid: Highly resistant to most acids, maintaining their mechanical properties
Alkali: Withstand exposure to most alkalis with minimal degradation
Organic Solvent: Generally compatible with a variety of organic solvents
Continuous Operating Temperature Range (°C): -150 to 70
Short Term Exposure (°C): 100
Melting Temp (°C):140 - 152
Suggested Applications
Strength members in lightweight composite assemblies and hybrid cable constructions
Robotic tendons act as flexible elements that transmits force from an actuator to a moving joint.
Timing, guide, and reinforcement cords in low-load mechanical systems and assemblies
Tethers, lanyards, and retention lines for industrial, marine, and outdoor applications
Metal wire replacement where corrosion resistance, flexibility, and weight reduction are required
Abrasion-resistant cordage for repeated flexing and contact environments
Sporting, fishing, and bowfishing lines requiring high tensile strength and minimal water absorption
General utility and industrial cordage for long-term service in wet, UV-exposed, or chemically harsh environments
