Author：hlyb Add Time：2016-03-29 17:20:30

1. Scope of application

Low smoke halogen-free flame retardant tape is made of glass fiber tape impregnated with flame-retardant adhesive without any halogen. It has high flame retardant property after curing. It is suitable for all kinds of low smoke halogen-free flame retardant cable, fire-resistant cable core and cable wrapping.

2. Technical conditions

2.1 appearance requirements

The burning band is a white double-sided dipping flat sheet, and the surface should be smooth and smooth without wrinkles and other mechanical impurities; The edges of both ends of each roll should be flat and clean without cracks.

2.2 dimensions and tolerances

See Table 1.

Table 1 dimensional requirements of low smoke halogen free flame retardant tape

Width and tolerance mm

Thickness and tolerance mm

Inner hole of each roll mm

Outer diameter of each coil mm

15～40±1.5
