Abstract: Disclosed is a flame retardant composition having excellent flame retardancy and processability, providing a flame-retardant synthetic resin composition including this flame retardant composition and having excellent flame retardancy and processability. Specifically, the following components are used in combination: as component (A), 20 to 50 parts by mass of at least one type of melamine salt selected from the group consisting of melamine orthophosphate, melamine pyrophosphate, and melamine polyphosphate; as component (B), 50 to 80 parts by mass of at least one type of piperazine salt selected from the group consisting of piperazine orthophosphate, piperazine pyrophosphate, and piperazine polyphosphate (the total of component (A) and component (B) is 100 parts by mass); and as component (C), 0.01 to 20.0 parts by mass of a bicyclophosphoric ester compound represented by the following general formula (1). The details of formula (1) are as described in the Description.

Abstract: A flame retardant composition containing a piperazine phosphate, a melamine phosphate, and an oil having a siloxane bond and a specific gravity of 0.930 to less than 0.970 at 25° C. The oil is present in an amount of 0.01 to 5 parts by mass per 100 parts by mass of the sum of the piperazine phosphate and the melamine phosphate. The flame retardant composition preferably further contains 0.01 to 5 parts by mass, per 100 parts by mass of the sum of the piperazine phosphate and the melamine phosphate, of a methylhydrogen silicone oil having hydrogen as part of the side chains of polysiloxane and a specific gravity of 0.970 to less than 1.01 at 25° C.

Abstract: Provided are a flame-retardant polyolefin resin composition with high flame retardancy, particularly sufficient flame retardancy to meet the UL94 5VA standard and a molded article with high flame retardancy, particularly sufficient flame retardancy to meet the UL94 5VA standard. The composition includes 100 parts by mass of a polyolefin resin, (A) 10 to 60 parts by mass of at least one melamine salt selected from the group consisting of melamine orthophosphate, melamine pyrophosphate, and melamine polyphosphate, (B) 15 to 90 parts by mass of at least one piperazine salt selected from the group consisting of piperazine orthophosphate, piperazine pyrophosphate, and piperazine polyphosphate, and (C) 10 to 140 parts by mass of glass fiber.
