Plastic article having flame retardant properties

摘要

A flame retardant article produced by forming a thermoplastic material around at least a portion of a core of partially cured phenolic resin is disclosed. The article has reduced flammability and improved dimensional stability when exposed to flame compared to an article consisting solely of the thermoplastic material. By positioning the thermoplastic between the core and at least all surfaces of the article which may become directly exposed to fire or heat when the article is in use, it is possible to impart the flexibility, colorability and impact resistance characteristics of thermoplastic materials to the article. At the same time, the inner core of the phenolic resin reduces the flammability and improves the dimensional stability of the article when the article is exposed to flame.
