弹性体特性简介
Introduction to Elastomer Characteristics
机械性能NDI对称的化学结构，决定机械性能优异，以NDI为原料所制得的弹性体，因为NDI形成的刚性段极性大，分子对称性好，结构紧密，所以制品具有优良的耐热性，Ultrallan的耐热温度为100度，短时间使用时为150度。承载能力，蓄能能力强，抗切割磨性，低温耐冲击性(脆性温度-65度无破坏)，耐溶剂性，耐油，耐气候，耐老化等特性非常优异。
机械性能
MECHANICAL BEHAVIOR
The NDl symmetrical chemical structure leads to its excellent mechanical properties. The elastomer made of NDl has excellent heat resistance due to the high polarity of the rigid chain, pertect molecular symmetry, and unique structure of itself Ultrallan* futures excellent properties in all aspects such as heat resistance of 100°C and 150° for short term, bearing capacity, energy storage capacity, cut-resistance, wear resistance, shock resistance at low emperature integrity at brittle temperature of -65C, solvent resistance, oil resistance, weather resistance and aging resistance
柔韧性由于NDI的高对称性，制得的弹性体分子链段均匀，分子内作用力大，且聚合物分子量分布均匀，应力平衡，使得弹性体有很好的柔韧性，在高硬度下仍具有良好的弹性及伸长率。

FLEXIBILITY
Due to the perfect molecular symmetry of NDl, elastomers made of which has characteristics of uniform molecular chains, stronger intramolecular force, narrow molecular weight distribution, and balanced stress, which brings higher flexibility, elasticity, and elongation on condition of its high hardness.
动态特征NDI制成的浇注型弹性体和泡沫NDI制品具有优异的动态特征和耐磨性，且阻尼小、回弹性高、内生热少，可应用于高动态载荷和耐热场合。
动态特征
DYNAMIC FEATURES
The cast elastomers and foam products made of NDl have excellent dynamic characteristics, wear resistance, low damping, high resilience, and lower internal heat-generation, which can be applied to high dynamic load and heat resistance scenarios.
耐磨性用NDI制成的模压制品，撕裂强度高、磨损小、压缩永久变形低和回弹性优异。高硬度下仍具有优异的弹性和吸振性。
