11 14, 2024

天然橡胶表由于表现出色而广泛用于各个领域. What is the hardness of natural rubber sheet? Let’s answer this question for you from JD Rubber.

The hardness of 天然橡胶板 is generally between 50-85A. The thickness of natural rubber sheet: 1-50毫米, 宽度: 0.5-2m, 长度: 10-20m. 天然橡皮纸的原材料是天然橡胶乳胶, 主要由聚合的高分子量乳胶组成.

天然橡胶板
Performance characteristics of natural rubber sheet:

1. 良好的弹性, 3-6MPA的弹性模量;

2. 天然橡胶板是一种结晶橡胶, which is stretched into crystals under the action of external force. 自我修复的强度很大; 平均分子量很大, 机械强度很高.

3. 由于天然橡胶板的分子量分布很大, 它具有良好的处理和制造属性. It has good dispersibility and miscibility with auxiliaries, and is easy to process and bond with fillers and most other rubbers.

4. 良好的渗透性, 耐寒性, 电绝缘和热绝缘特性.

5. 耐老化是天然橡胶的致命弱点.

6. 分子链不包含极性官能团, 因此,天然橡胶板是一种非极性橡胶. 它只能承受一些极地溶剂. 所以, 它的耐油性很差. Good alkali resistance, but not strong acid resistance.
