Vulcanized Fiber Epoxy Canvas Tube
Vulcanized fiber epoxy canvas tube combines a vulcanized-fiber inner layer with an epoxy-impregnated glass-fiber canvas outer layer. The construction is intended for electrical insulation and fuse components where a machinable fiber core and a reinforced outer surface are required. As a direct manufacturer and supplier, we provide Vulcan Fiber Combinate Epoxy Canvas Tube in made-to-drawing sizes with low minimum order quantities and fast sampling for both prototype and production runs.
Construction and selection
| Item | Engineering choice | Confirm for quotation |
|---|---|---|
| Inner layer | Vulcanized fiber for insulation and arc-quenching applications | Inner diameter, wall thickness, length |
| Outer layer | Epoxy-bonded glass-fiber canvas | Canvas grade, resin system, surface finish |
| Machining | Cutting, drilling and turning can be reviewed against the drawing | Tolerances, end geometry, slots and holes |
| Validation | Electrical and dimensional values depend on the final construction | Voltage, temperature, test method and batch quantity |
Typical uses
- Fuse cutout and current-limiting fuse components
- Electrical insulation sleeves and liners
- Machined insulating parts that need a reinforced outer layer
RFQ checklist
Send the drawing or sample, inner and outer diameters, finished length, tolerances, required electrical rating, operating temperature, quantity, packaging requirements and any inspection standard. We will confirm material construction and manufacturability before production.

Frequently asked questions
What is a vulcan fiber combined with epoxy canvas tube?
It is a composite built from vulcanized fiber and epoxy-impregnated canvas, combining the machinability of vulcan fiber with extra mechanical strength from the canvas layer.
When is this composite chosen over plain vulcanized fiber?
It is selected when the part needs higher impact and structural strength while keeping good electrical insulation and machinability.
Vulcan fiber epoxy canvas tube: machinability and strength from one plant
The point of this composite is the split of duties: the vulcanized fibre bore machines cleanly, while the epoxy-impregnated canvas shell carries impact and structural load. Get the balance wrong and either the bore chips or the wall cracks. We build both layers in-house, so fibre grade and canvas weight can be re-balanced for your part instead of being fixed by whatever a supplier happens to stock.
- Direct factory pricing on vulcan fiber epoxy canvas tube
- Low and prototype quantities accepted while the layer balance is set
- Bore machinability and shell strength tuned to your drawing
- ISO 9001 quality system across fibre forming, canvas lay-up and cure
- SGS material testing available on the composite
- RoHS and REACH documentation on request
Vulcan fiber epoxy canvas tube: ordering details
What is the smallest quantity of epoxy canvas tube you produce?
Trial and prototype quantities are accepted, since the fibre-to-canvas balance is usually still being optimised at that stage.
Which quality system covers this composite tube?
It is made under an ISO 9001 quality system; SGS material testing is available and RoHS and REACH documents are issued on request.
How long before I receive a quotation?
A technical review of the drawing is returned within one working day, with the quotation following once fibre grade, canvas weight and quantity are agreed.
