Impregnating polymer beads with insecticide |
摘要 |
Polymeric beads made by a suspension or an emulsion process may be concurrently impregnated with blowing agent, an insecticide and a flame retardant, if required. The resulting bead is then washed and dried and then may be used for making a foam structure such as a sheet. The resulting foam sheet may be used in the construction industry, particularly where there is a concern of insect infestation. |
