Handling precautions
When used for their intended purpose and under normal conditions of industrial handling, Indopol® polybutenes do not present any appreciable hazards. Precautions should, however, be taken to prevent entry into the eyes and to avoid prolonged or repeated contact with the skin particularly when the product is handled at elevated temperatures. Wear protective equipment when handling hot polybutene. Goggles, face shield or other full-face protection should be worn if potential exists for direct exposure to aerosols or splashes or when the material is handled hot. Wear heat-resistant protective gloves, clothing and face shield that are able to withstand the temperature of the hot product. Exposure to mist and fumes, which may arise from the lower molecular weight products handled at elevated temperatures, should be minimized by the provision of adequate ventilation. If heated and ventilation is inadequate, use respirator that will protect against organic vapor and dust/mist.
A high intensity heat source should not be employed when heating the higher molecular weight grades to improve handling characteristics, since their viscous nature prevents rapid convection of heat away from such a source. In addition to mist and fumes, short-chain hydrocarbons with low flash points can be generated rapidly at temperatures above 200°C-250°C depending on the molecular weight of the polybutene. Consequently, drums should be vented during the heating operation. For prolonged storage at temperatures of 60°C and above, keep polybutene in rust-free tanks and exclude oxygen by use of a nitrogen blanket. Suitable storage materials are mild steel / carbon steel.
Always consult the relevant Material Safety Data Sheet for specific information on recommendations for handling and safety.
