Fluoro rubber ALD-FL-70B
Product Description:
FL-70B Fluorine rubber compound is fast vulcanized, anti-scorch, used for watch straps, low-pressure variable, high strength, high wear resistance, methanol gasoline, fuel oil, antistatic and other varieties. It is suitable for the production of O-rings, Y-rings, pure rubber gaskets, extrusion automatic rubber rolls, large-section fluorine rubber products, etc.
Features:
Excellent high-temperature resistance, resistance to most oils and solvents (except ketones, and esters), excellent weather resistance, ozone resistance, operating temperature range -30°C-260°C.
Storage: Precautions for use <Rubber Mixture>, store in a cool place, and use within the shelf life. Fluorine rubber must be isolated from water and stored in an environment.
Safety measures in use:
① Please use the vulcanized rubber compound in a well-ventilated place, and install a local exhaust device if necessary.
② The environment of rubber products is the high temperature when used, and may come into contact with the skin during use, so wear gloves for protection. Fluorine rubber is strictly prohibited from being polluted by sulfur.
