| 摘要 |
The present invention provides a polyolefin resin composition with sufficient flame retardancy to pass UL94 5VA without using a halogen flame retarding agent that produces harmful gas during combustion, and specifically provides a flame retardant polyolefin resin composition containing, as flame retardant components of the polyolefin resin, (A) a (poly)phosphoric acid compound expressed by general formula (1) and (B) a (poly)phosphate compound expressed by general formula (3), and preferably (C) zinc oxide and (D) a drip preventing agent, and that satisfies UL94 5VA. Note that the details of general formula (1) and general formula (3) are as disclosed in the specification. |
