Abstract: Polyamide6 pole shoe was prepared via two methods: (1) Using a blend of polyamide6 with masterbatches of fire retardant and antistatic agent;(2) Coating fire retardant and antistatic agents on the surface polyamide6 pole shoe. Fire retardant, antistatic, and mechanical properties of the pole shoe were studied. The pole shoe prepared via blending method gave rise to outside and inside surface resistance of 2.1×106Ω and 6.4×106Ω, burning times with and without flame 1 s and 10 s, respectively. However, its compressive strength was poor. The corresponding properties by coating method were 8.3×106Ω, 3.2×107Ω, 2 s, and 12 s, with the compressive strength obviously improved.

Key words: fire retardancy, pole shoe, polyamide 6, antistatic property
