What is Polyester Glass Fiber?

Polyester glass fiber cloth is a common textile covering, wrapped with conductor wires in a heat-treated combination. This method can be made of single or double glass yarn. Polyester, epoxy or silicon varnish is available. Usually used for standard temperature applications with or without appropriate varnish. It can be applied to bare conductors, various types of coated conductors or other insulating layers. This allows the yarn to wrap around the wire, creating a protective layer over the wire. The yarn is then cured at high temperatures and fused with the wire to become a protective insulating barrier. Once complete, the insulation allows the wire to function properly at temperatures between -196C and 300C when a glass fiber cloth is used.

The Components of Polyester Glass Fiber

Polyethylene terephthalate, bbbreviation for PET, mainly refers to Polyethylene terephthalate, which is a polymer compound formed by the condensation of two or multiple acids and two or multiple alcohols. Polyethylene terephthalate (polyethylene terephthalate), which is formed by condensation polymerization of polyethylene terephthalate (PTA) and ethylene glycol (EG) as raw materials, is the world's earliest industrialized production and widely used in polyester products. It is also one of the most widely used polymer materials in the world. The fiberglass to which it is added is best at resisting flaking, abrasion and cracking. It is also resistant to corrosion and can withstand environmental and chemical degradation. Polyester fiberglass is more durable as a protective measure than other polyester materials and is more suitable for short-term repairs. Polyester fiberglass also costs more than other products because it has the ultimate durability and formulation prerequisites.

Advantages of Polyester Glass Fiber

Polyester glass fiber cloth has high insulation performance, anti - UV, anti - static. Maintain safe working condition electrically. It is mainly used in industry: heat insulation, fire prevention, flame retardant. The material absorbs a large amount of heat when burned by a flame and can prevent the flame from passing through and isolate the air. Polyester glass fiber cloth is usually used as reinforcement materials in composite materials, conductive wire, thermal insulation materials, electric roadbed board and other fields of the national economy. It is often used in motors and control of all types of electromagnetic coils, as well as a variety of other applications. Especially suitable for harsh mechanical environments due to wear resistance/vibration and the ability to bond well with various resins.
