Natural rubber sheet is widely used in various fields due to its excellent performance. What are the components of natural rubber sheet? Let’s answer this question for you from Jingdong Rubber.

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 forms 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 fillers and other rubber compounds, making it easy to process and bond with mechanical processing and bonding.

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. It is good in alkali resistance, but not in strong acid.
