Flame Retardant
Halogen-free flame retardant system achieving UL94 V0 — for connectors, circuit breaker housings and electronic structural parts.
01 Material Overview
The flame-retardant series uses a halogen-free system that reaches UL94 V0 while preserving as much of POK’s toughness and hydrolysis resistance as possible. JH960NH is the unfilled flame-retardant grade for general electronic housings; JH960G6NH adds 30% glass fibre for higher stiffness and heat deflection temperature, and is used for connectors, circuit breakers and relay housings.
Adding a flame retardant reduces impact strength and narrows the processing window, so melt temperature control during moulding must be tighter to avoid decomposition of the retardant. We recommend running glow-wire and comparative tracking index (CTI) validation alongside the trial moulding.
If your project references a specific standard (GB/T 5169, IEC 60695 and so on), tell us at the selection stage and we can provide the corresponding test reports or arrange third-party testing.
