What is the hardness of natural rubber sheet

天然橡胶板

Natural rubber sheet is widely used in various fields due to its excellent performance. 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: 1-50mm, width: 0.5-2m, length: 10-20m. The raw material of natural rubber sheet is natural rubber latex, which mainly consists of polymerized high molecular weight latex.

Performance characteristics of natural rubber sheet:

1. Good elasticity, elastic modulus of 3-6MPa;

2. Natural rubber sheet is a crystalline rubber, which is stretched into crystals under the action of external force. The self-healing strength is large; the average molecular weight is large, and the mechanical strength is high.

3. Due to the wide molecular weight distribution of natural rubber sheet, it has good processing and manufacturing properties. It has good dispersibility and miscibility with auxiliaries, and is easy to process and bond with fillers and most other rubbers.

4. Good permeability, cold resistance, electrical insulation and heat insulation properties.

5. Aging resistance is the fatal weakness of natural rubber.

6. The molecular chain does not contain polar functional groups, so natural rubber sheet is a non-polar rubber. It can only withstand some polar solvents. Therefore, its oil resistance is very poor. Good alkali resistance, but not strong acid resistance.
