Refrigerant 14 (Tetrafluoromethane)

CAS №: 75-73-0 EC №: 200-896-5 Synonyms: Tetrafluoromethane (R14), Carbon fluoride; Freon 14; Perfluoromethane; Carbon tetrafluoride; Halocarbon 14; R 14; PFC 14; Molecular formula: CF4 Tetrafluoromethane, also known as carbon tetrafluoride, is the simplest fluorocarbon (CF4). Halon 14 has very high bond strength due to the nature of the carbon–fluorine bond. Use Tetrafluoromethane is used: • as a low temperature refrigerant; • in electronics microfabrication alone or in combination with oxygen as a plasma etchant for silicon, silicon dioxide, and silicon nitride; • in high-voltage equipment production; • in neutron detectors.

Safety Depending on the concentration, Refrigerant 14 inhalation can cause headaches, nausea, dizziness and damage to the cardiovascular system (mainly the heart). Long-term exposure can cause severe heart damage. Due to its density, tetrafluoromethane can displace air, creating an asphyxiation hazard in inadequately ventilated areas. But R-14 is a non-flammable and low toxic gas at normal temperature. Packaging: • steel cylinder 10 kg, • steel cylinder 35 kg, • ISO tank.
