Kevlar Aramid Chopped Fiber / Sewing Thread
Up to 400°C
Main applications
chopped fiber and sewing thread that maximise composite strength
Key Features
High-strength chopped aramid fiber
Chopped Kevlar (aramid) fiber dispersed through resin, cement or rubber composites — greatly raising tensile and impact strength
Heat-resistant sewing thread
Aramid sewing thread rated 300–400°C — made for sewing high-temperature protective jackets and blankets
300–400°C heat resistance
The heat resistance of aramid — performance no ordinary thread can match when sewing hot-service jackets
Fatigue and flex resistance
The aramid characteristic means no loss of thread strength through repeated sewing and flexing
Raises composite tensile and impact strength
Chopped fiber reinforcement disperses evenly through rubber and resin matrices, preventing cracking

Notes
- ※Chopped length and loading directly affect composite properties — tell us the resin type and target properties and we will recommend a specification.
- ※The thread sews on an ordinary sewing machine — we recommend replacing standard nylon thread with it on high-temperature jackets.
