Toxic fumes also can occur in post-processing operations. Therefore, it is important that adequate ventilation and proper operating conditions be provided and periodically checked to ensure that no hazardous fumes are present in the work area. In the event of a fire, personnel entering the area should use a fresh air supply. An electrostatic charge potentially can build up when pouring powder or pellets. Combustion and Pyrolysis Thermal decomposition of resins produces fumes that can be potentially hazardous.
Decomposition is a function of both processing temperature and time at that temperature.
It should be noted further that some decomposition can occur below the recommended processing temperature limits for all resins. Toxicity Various functionalized polyolefins, in film form, have been used for more than 25 years in industrial applications and food packaging. Thermal Burns Precautions for working around resin processing equipment should be obtained from the vendors of these machines. If contact with molten polymer is made, immediately flush the burned areas of the skin with cold running water or treat with ice packs. Continue the treatment for 15 minutes or until the pain has diminished.
