Acrylic fiberglass sleeving, also known as acrylate paint tube, is a Class F insulation sleeve made by weaving a tube blank with alkali-free fiberglass and coating it with acrylate resin, which is then cured through high-temperature drying.

Features: Heat-resistant up to 155℃, oil and wear-resistant, good softness and elasticity, economical price, excellent compatibility with Class F impregnating varnish. It is the standard insulating sleeve for motors, electrical appliances, and instruments.

Temperature range: -30℃ to 155℃ for long-term continuous operation, and up to 180℃ for short periods (several hours)

Insulation grade: Class F insulation (155℃)

Voltage withstand level: 1.5kV, 2.5kV, 4kV, 7kV (divided into 403/404/405 types)

Flame retardant grade: fiber non-combustible, coating self-extinguishing, UL94 V2 grade

Environmental standards: Compliant with RoHS and REACH environmental requirements

Material structure: E-glass fiber braiding + acrylate resin coating (single coating)

Appearance color: natural color (white/transparent), yellow, black, red/blue/green (customizable)

Physical properties: soft and elastic, wear-resistant, oil-resistant, benzene-resistant, resistant to bending, high tensile strength

Electrical performance: stable dielectric properties, uniform breakdown voltage, and good insulation reliability

Weather resistance: resistant to oil and solvents, anti-aging; not resistant to water / general moisture resistance

Scope of application

F-class motors, transformers, frequency converters, instruments, household appliances, industrial appliances, internal wiring harnesses for new energy motors, impregnating varnish for winding insulation, automotive low-voltage wiring harnesses, lighting wiring, and other scenarios requiring high temperature resistance, oil resistance, and insulation protection.
