Silicone Coated Fiberglass Sleeve

Description

Glass fiber silicone sleeve is a new type of cable protection material, which is braided by glass fiber and coated with silicone inside. It has the characteristics of fire prevention, high temperature resistance, corrosion resistance, wear resistance, etc., and can effectively protect cables, lines and other equipment from being damaged under high temperature, fire, etc., thereby ensuring the normal operation of equipment and personal safety. Glass fiber silicone sleeves are widely used in electric power, petroleum, chemical industry, metallurgy, shipbuilding, aerospace and other fields to protect cables, lines and other equipment.

Fire spreadability	Burning time	S	≤60
	Visual inspection	—	The indicator flag should not burn on any of the three specimens. Nor should the cotton be ignited by ignited or burning particles or by ignited drops.
Soldering heat resistance		—	Pass (Only for sleeve with nominal inner diameter ≤ 5 mm)
Volatile content	Low content level	%	—			≤1.0		≤0.7
	Other level					≤1.5		≤1.5
Bending after heating		—	The coating has no visible cracks or peeling off, allowing the color to become darker (test temperature: 180±3℃)
Bending at low temperatures		—	The coating has no visible cracks or peeling off (test temperature: ≤-70～5℃)
Hydrolysis resistance of paint layer		—	There is no migration of the coating, no adhesion between the hose and the paper and the hose test piece, and no discoloration of the paper.
Shelf life		—	6 months
