20mm rubber stopper

There are many differences between butyl and natural rubber. The main advantage is that butyl rubber has better chemical stability and aging resistance than natural rubber. It has the elasticity of natural rubber and does not contain protein ingredients, but it does not have butyl. Chemical inertness and aging resistance

There are many differences between butyl and natural rubber. Butyl rubber is a synthetic elastomer known for its excellent sealing properties, chemical resistance, and flexibility. The product also has low air permeability, good airtightness, and good resistance. Ozone resistance, chemical resistance, electrical insulation, flexibility resistance, heat aging resistance, energy absorption, and other characteristics.

The butyl rubber stopper is an off-white rubber-like solid with a density of 0.92g/cm3. It is odorless, insoluble in water, and soluble in hexane and chloroform. The product also has low air permeability, good airtightness, and good resistance. Ozone resistance, chemical resistance, electrical insulation, flexibility resistance, heat aging resistance, energy absorption and other characteristics.
