Decreasing the combustibility of polyolefins using microencapsulated fire retardants

A method of decreasing the combustibility of polyolefins by incorporation of microencapsulated fire retardants (ME FR) in the polymer melt was developed. It was found that PE and PP containing ME FR in PE and polyvinyltriethoxysilane (PVTES) shells belong to the category of difficult to burn materials. The study of the thermophysical and physicochemical characteristics of modified PE and PP demonstrated the major possibility of realization of the method for fabrication of polyolefins with a low fire hazard.
