Kebos new-type non-adhesive one-time molding large thickness new material synthetic rail sleeper is made of continuous glass fiber reinforced polyurethane resin foam, with the advantages of low carbon and environmental protection, lightweight and high strength, good marital resistance, easy processing and easy installing etc. Its service life could lengthen up to 50 years, and it is the best alternative to wooden sleeper and concrete sleeper, which can be widely used in urban rail transit, ordinary railroads, heavy railroads, high-speed railroads, vehicle segments, switching areas, bridges and other road sections.
1. Kebos new-type synthetic sleepers of 300mm thick and below is in dispense with adhesion process, whose thickness is far greater than maximum 70mm of synthetic sleeper blanks by other global manufacturers. This can greatly improve the uniformity and reliability of synthetic rail sleepers.
2. Easy construction: light weight and high strength, convenient to transport and can be cut and punched on site. With easy installation and high precision, it can greatly shorten the construction cycle. According to customer requirements, there can be a variety types of design and processing in order to coordinate with installation.
3. Spike resistance: High spike resistance could ensure the connection of fastener system to be more stable and reliable.
4. Long service life and maintenance-free: Aging resistance with long service life, excellent weather resistance and fatigue resistance.
5. Insulation and waterproof: With good insulation and anti-rust specialties, it can effectively prevent stray current and water erosion.
6. Repairable: It can be repaired on-site through repair agent, the strength after repairment is greater than the original one.
