1. Environmental protection and non toxicity: PGE material is thermoplastic polyester elastomer, without any vulcanization reagent. It has passed the FDA certification and met the material requirements for direct contact with food.
2. Economy and practicability: wide range of application temperature, - 50 ℃ - 80 ℃; excellent weather resistance, ozone and ultraviolet protection; bright colors and various combinations; good wear resistance. The strength and elongation change little after 500h aging test, which is far higher than the standard value. The service life of the runway made of this material is greatly prolonged for at least 10 years.
3. Safety protection. The physical performance of PGE material runway shows that it has excellent performance. The simulation test of the mobile robot shows that its shock absorption and vertical deformation are stable, which are in the middle of the optimal control range! It is especially suitable for large, middle, primary schools and kindergartens.
4. Environmental friendliness: the material has no peculiar smell, and the data of harmful substances are mostly undetected or far less than the standard value, which will not be harmed and polluted to the participants and the surrounding environment. If necessary, special treatment can be adopted to continuously release negative oxygen ions from the runway and improve the local air environment of the site.
5. 100% recovery: the biggest feature of this material is environmental protection. It can be recycled 5-6 times without obvious performance degradation, which meets the international environmental protection requirements. Recycling after 10 years of use is the biggest contribution to environmental friendliness, which solves the problem that solid waste cannot be treated after the runway of various materials is scrapped.
