Introduction to Synthetic Sleepers with Matching Special Repair Adhesive
Synthetic sleepers are advanced structural components engineered to replace traditional timber or concrete sleepers in rail, industrial, and landscaping applications. Made from high‑performance composite materials such as recycled plastics, fiberglass‑reinforced polymers (FRP), or other engineered polymers, synthetic sleepers offer exceptional durability, consistent quality, and superior resistance to rot, corrosion, insects, and moisture. Their uniform dimensions and engineered strength make them ideal for demanding environments where long‑term performance and low maintenance are critical.
To maximize the service life and ensure reliable field performance, matching special repair adhesive is supplied specifically for use with synthetic sleepers. This high‑strength adhesive is formulated to bond effectively with composite materials, creating a resilient and long‑lasting repair solution for:
Cracks or surface damage.
End splits from installation stresses.
Bolt or fastener hole repairs.
Localized structural restoration during maintenance.
The adhesive’s unique chemistry is designed to:
✔ Achieve excellent adhesion to polymer and composite surfaces
✔ Cure quickly under varied environmental conditions
✔ Provide flexibility compatible with sleeper thermal expansion
✔ Resist water, UV exposure, and chemical contaminants
Kefei's synthetic sleeper is equipped with special repair adhesive, which can be used when the sleeper drilling operation is wrong during installation or when the road stud is loose after operation, and its strength is close to the same as that of the sleeper body.
Different from the conventional sleeper repair adhesive, the special adhesive of Kefei adopts double spiral mixing nozzle for automatic mixing, with high mixing and proportioning accuracy, and no longer needs on-site manual compounding.
Advantages of the Adhesive:
Excellent adhesion to synthetic composite surfaces
Fast curing in various environmental conditions
Flexibility compatible with sleeper expansion and contraction
Resistance to water, UV, and chemical exposure
Applications
