Natural Rubber Parts
Among all the common-use rubbers, Natural Rubber is the most widely used. NR is an excellent choice if you require high elasticity rubber. The natural rubber parts produced by Jiangzhi are widely used in industry, agriculture, machinery manufacturing and other industries.
What is Natural rubber?
Unlike man-made synthetic rubber, natural rubber is extracted and processed from plants. It has high wear resistance, resilience, insulation, breaking strength and elongation. It is easy to age in air, easy to expand and dissolve in mineral oil or gasoline. However, after proper treatment, it has the characteristics of oil resistance, acid resistance, alkali resistance, heat resistance, cold resistance, and pressure resistance. Widely used in agriculture, national defense, transportation and daily life.
