Plastic sleeper: the material of plastic sleeper is a kind of thermoplastic engineering plastic (high molecular polyethylene), which is waterproof, moisture-proof, moth proof and corrosion-resistant, and has a longer service life than wooden sleeper. In addition, this material also has the following characteristics:
1. With the inherent toughness and flexibility of plastics, it can eliminate the noise and vibration generated by the train on the reinforced concrete sleeper by 2-3 times; It can shorten the braking distance of the existing railway train by 1-2 times;
2. Wear resistance. The higher the molecular weight, the stronger the wear resistance.
3. Wide application range - 50 + 70 ° C;
4, anti-aging, acid, alkali resistance, humidity resistance, stable performance, and the service life is 50-70 years.
5. The material is light, easy to disassemble and handle;
6. Protect the environment. Composite HDPE is a by-product of petroleum, which can save mineral energy, forest wood and protect the environment;
7. Strong load-bearing capacity, bending rather than breaking under strong pressure.
Features: Plastic sleepers are maintenance free, paint free and recyclable. After testing, they can be used normally in the temperature range of - 37 ℃ ~ 100 ℃.
