05 / Chemical resistance
PTFE & Fluoropolymer Tube
Low-friction, high-temperature tubing for demanding electrical and fluid paths.
Request material options →Application engineering
Choose by failure mode, not only by diameter.
For EV high-voltage harnesses, start with heat, flame retardancy, color identification, abrasion and long-term assembly reliability.
Qualification evidence
Make compliance easy to review.
Each production product page should connect the commercial claim to a downloadable datasheet, certification scope, test method, size table and traceable batch information.
Certification numbers and exact scope must be confirmed before production launch.
Certification scope
Display the certified product family, temperature class, voltage and flame rating—not only a certificate logo.
Flame performance
Explain applicable standards and provide matching test evidence for the selected series.
Material compliance
Keep declarations current and tied to product codes, materials and requested markets.
Batch traceability
Connect production lot, inspection record, dimensions and customer specification.
From yarn to verified sleeve
One manufacturing path, documented.
FRT specializes in electrical insulation tubes and integrates braiding, coating or extrusion, curing, cutting and inspection. Production details shown here are based on the customer’s existing materials and require final capacity confirmation.
- 01Specification review
Application, material, dimensions, temperature, voltage and compliance.
- 02Sample & validation
Confirm fit, processability, marking, packing and test requirements.
- 03Controlled production
Defined process checks from raw material through finished tubing.
- 04Inspection & delivery
Batch record, packing identification and requested quality documents.
