Poly(dimethylsiloxane) Specification

1、Fire Fighting Measures of  POLYDIMETHYL SILOXANE(9016-00-6)
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
2、Accidental Release Measures of  POLYDIMETHYL SILOXANE(9016-00-6)
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Clean up spills immediately, using the appropriate protective equipment. Provide ventilation.
