1、具有優(yōu)秀的耐候性，對光、熱、臭氧等應(yīng)具有肯定的承受能力；
1, with good weather resistance, light, heat, ozone and other should have a certain ability to withstand;

2、具有抗水滲透和耐酸堿性能；
2, with water permeability and resistance to acid and alkali resistance;

3、對外界溫度和外力具有肯定的適應(yīng)性，即材料的拉伸強(qiáng)度要高，斷裂伸長率要大，能承受溫差轉(zhuǎn)變以及各種外力與下層伸縮、開裂所引起的變形；

3, the external temperature and external force has a certain adaptability, that is, the tensile strength of the material should be high, the elongation at break is large, can withstand the change of temperature and various external forces and the base expansion, cracking caused by the deformation;

4、整體性好，既能保持自身的黏結(jié)性，又能與下層牢固黏結(jié)，同時在外力作用下，有較高的剝離強(qiáng)度，形成穩(wěn)固的不透水整體。
4, the integrity of the good, not only to maintain their own bond, and can firmly bond with the grass roots, while the external force, a higher peel strength, the formation of a stable impervious to the whole.
