The present invention relates to an insulating composition.

II has suddenly increased. As a standard for this flame retardancy, there is IEEE (Honda Electrical and Electronics Engineers 1.η Association) Standard 383 V TF 'I'' (Vertical Tray Combustion Test), which simulates the actual installation situation of electric wires and cables. It became like -ffj to adopt the flame-retardant Shiba 1'(-) if it passed the combustion test.

Although it exhibits sufficient flame retardant properties, the halogen-based scum generated during this process is often toxic, such as hydrogen chloride, and it produces a large amount of smoke containing such toxic gases. This may impede visibility, impede evacuation and firefighting activities in the event of a fire, or cause a primary disaster due to the harmful effects of the toxic residue on the human body.Furthermore, halogen residue may be released into the air. It reacts with moisture in the water, becomes hydrohalic acid, and leaves the switchboard at t5.

However, these inorganic hydroxides have inferior flame retardancy compared to the halogenated and phosphorous compounds mentioned above, so there is a problem that they must be mixed in larger amounts. However, there is a problem in that mechanical properties such as tensile properties and scratch resistance are significantly reduced.
