用于公路的防撞护栏。为了保护行车人的安全，减轻撞击带来的伤害。

聚氨酯是一种新兴的有机高分子材料，因其卓越的性能

而被广泛应用于国民经济众多领域。产品应用领域涉及轻工、化工、建筑、

建材、汽车、国防、航天、航空....聚氨酯材料的一般优点： 

硬度范围宽(邵A15～邵D90)

 在相同硬度下，比其它的弹性体承载能力高

 耐磨、抗冲击性高

 回弹范围广、压缩60%回复率100%。

 适于高频挠曲应用

 低温柔顺性好

 采用特殊的配方，140℃下稳定

不受臭氧侵蚀的影响，抗霉菌

 耐辐射，耐腐蚀，耐高、低磨擦，不吸收雨水。

 可在标准设备上加工，可与木材、金属和大部分材质粘接

另还具有降低噪音的作用。

 广泛耐油、脂和化学品。用这种新型材料生产制造的防碰防撞设施，高弹性。

而且使用年限较高。可达30-50年。综合性价比非常高。

The used for highway crash barrier. In order to protect the safety of traffic, reduce the impact injuries.

Pu is a new type of organic polymer materials, for its outstanding performance

Is widely used the compilation of national many other fields. Application covering light industry, chemical industry, construction,

Building materials, automobile, national defense, aerospace, aviation... Polyurethane materials general advantage:

Hardness limits wide (shao A15 ~ shao D90)

In the same hardness, other than the elastomer carrying capacity is high

Wear-resisting, high impact resistance

The springback range, compression 60% recovery rate 100%.

Suitable for high frequency buckling applications

Low temperature and good sex

The use of special formula, 140 ℃ steady

From the influence of ozone erosion resistance, mould

Radiation resistance, corrosion resistance, resistance to high and low friction, don't absorb the rainwater.

But in the standard equipment processing, but with wood, metal and most of the material cementation

The other also has reduced the effects of noise.

Widespread resistance to oil, grease and chemicals. In this new material production of the touch bull facilities, high elastic.

And use fixed number of year is higher. Can be up to 30 to 50 years. Comprehensive price is very high.
