POLY VINYL CHLORIDE FOAM PROMOTERS |
摘要 |
The density of rigid foamed articles made by the thermal decomposition of a blowing agent in a vinyl chloride polymer is reduced by the use of a tin based blowing agent activator(s). The tin based activator also reduces the activation temperature of a chemical blowing agent, allowing for more optimal evolution of gas during plastic processing. Dibutyl tin oxide or tin maleates are superior activators of vinyl chloride polymer blowing agents. |
