There are three commonly used materials for sealing rings. A brief introduction to the performance is convenient for customers to choose
①Silicone: mainly resistant to high and low temperatures -50-200 degrees, aging resistance, relatively soft material, good sealing performance, the color is usually white and translucent, the thickness of the conventional size can generally be 0.2mm-20mm, please consult
②NBR: The main performance is oil resistance, temperature resistance is about 90 degrees, pressure resistance is better than silica gel, and the price is cheaper than the other 2 types.
③FKM: FKM is resistant to high temperatures up to 250 degrees, resistant to strong acids and alkalis, stable chemical properties, and relatively good pressure resistance.
