Hollow PE sleeper is a new type of composite material, which has physical and mechanical properties such as compression resistance and bending resistance comparable to hardwood, and its durability is significantly better than ordinary wood materials.
The main features of this product are:
1. It can be used in humid and watery environments, and it will not absorb moisture, expand and deform.
2. It can effectively eliminate insect harassment and prolong the service life.
3. Green environmental protection, no pollution, no pollution, recyclable.
4. It is simple and convenient to use and does not require special training.
5. No cracking, no swelling, no deformation, no maintenance and maintenance, easy to clean and save maintenance costs.
When extruding a suitable proportion of incompatible PS (polystyrene) and PE (polyethylene) mixtures for plastic sleepers,
Can form continuous structural blends of matrix resin (PE) reinforced by internally wound fibers (PS),
The resulting composite material has astonishing compressive strength,
The raw materials used are 20%~35% high melt strength PS and roadside recycled HDPE (high density polyethylene).
