HUAYE Tie Gum (Core Rubber) for Conveyor Belt Hot Vulcanization Splicing
HUAYE Tie Gum is an uncured core rubber compound engineered for hot vulcanization splicing on fabric, nylon (NN), and polyester (EP) carcass conveyor belts. Placed between belt plies at the splice joint, it cures under heat and pressure into a strong, continuous bond — and with 10 kg per roll and custom width/thickness available, your team gets exactly the size needed for the job, without compromising on splice strength.
- Conveyor belt tie gum for fabric, nylon & polyester carcass belts
- High bond strength between carcass plies
- Storage Life: 12 months (below 25°C, cool & dry)
- Custom width & thickness — made to order
HUAYE Tie Gum — also known as uncured intermediate rubber or core rubber — is an uncured rubber compound used to bond carcass plies (fabric, nylon, and polyester) during hot vulcanization splicing of conveyor belts. It is applied between belt plies at the splice joint, where heat and pressure cure it into a single, continuous bond across the repair. Model reference: HUAYE-50XX series (e.g. HUAYE-5001 = 500mm width × 1mm thickness).
Key Features
- High bond strength — forms a strong, durable joint between carcass plies
- Stable performance — consistent results under standard hot vulcanization conditions
- Long shelf life — 12 months when stored cool and dry (below 25°C)
- Made to order — custom width and thickness available to match your splice specification

Figures above were obtained under standard laboratory conditions. Actual performance may vary depending on surface condition, curing conditions, storage, and transport. For critical applications, we recommend a small trial splice or contacting us for technical guidance before full-scale use.
Handling Notes
Store in a cool, dry place, away from direct sunlight and heat sources.
Treat as a general non-flammable item during transport and handling.
Shelf life is 12 months when stored below 25°C — use within this period for best bonding performance.
Frequently Asked Questions
What is conveyor belt tie gum?
Conveyor belt tie gum, also called core rubber or uncured intermediate rubber, is an uncured rubber compound placed between carcass plies during hot vulcanization splicing to bond the belt joint together.
Is tie gum the same as core rubber?
Yes. “Tie gum,” “core rubber,” and “uncured intermediate rubber” all refer to the same type of product — the ply-bonding rubber used in hot splicing of fabric, nylon, and polyester carcass conveyor belts.
Can the width and thickness be customized?
Yes. Width and thickness are made to order. Our model code reflects this — HUAYE-5001, for example, refers to a 500mm width × 1mm thickness reference size, with other sizes available on request.
Is HUAYE tie gum suitable for steel cord conveyor belts?
Tie gum (core rubber) is intended for fabric, nylon, and polyester carcass belts. For steel cord belt splicing, ask us about HUAYE Cover Rubber, which covers a broader range including steel cord constructions.
How should tie gum be stored?
Store in a cool, dry place below 25°C. Shelf life is 12 months under these conditions. Treat as a general non-flammable item during transport.
