Safety and Handling
Handling and processing of fluoroelastomer must be done in ventilated areas to prevent personnel exposure to the fumes liberated during curing or use of cured rubber at high temperature. During the process, some fumes may generate at high temperature which are harmful for human beings. Fumes should not be inhaled, eye and skin contact must be avoided. In case of skin contact flush skin with cold water immediately. In case of eye contact, flush with water immediately and seek medical help. Smoking tobacco or cigarettes should not be
allowed in working area. Mixing agents that contain metallic particulate such as powdered aluminum can
rapidly decompose at high temperature; therefore do not use metallic particulate as mixing agent.
Fluoroelastomer should be stored away from heat. It should be kept in clean and dry area where it can be
protected until it is used. Please read the Material Safety Data Sheet before handling the product.
