In today’s era of rapid development of electricity, power products are constantly evolving and iterating. People have high requirements for product quality and service life, so related protection products are gradually being improved. Taking motor products as an example, motors are widely used, including automobiles, ships, wind turbines, etc. The fiberglass sleeve used to protect the cable joints on the motor is a very important part.
1. Meaning of the fiberglass sleeve
Fiberglass sleeve is an insulating sleeve, it is made of fiberglass and coated with silicone or acrylic. It can be put on the exposed wires to provide protection and insulation.
2. Classification of fiberglass sleeve
- Silicone fiberglass sleeve:
- Fiberglass sleeving is a special insulation material that is widely used in various fields due to its excellent thermal, electrical, insulating and mechanical properties. It is well known for its excellent heat resistance, flexibility and chemical inertness. Thus providing a flexible and durable protective barrier.
- Acrylic fiberglass sleeve:
Acrylic coated fiberglass sleeving is an insulating material consisting of a fiberglass core coated with acrylic resin. The outer acrylic resin coating is a plastic derived from acrylic. The acrylic coating provides additional protection and enhances the sleeving's resistance to moisture, UV radiation, and certain chemicals. This combination provides a variety of thermal, electrical, and mechanical properties that make it suitable for a variety of applications.
3. Application scenarios of fiberglass sleeve
The application scope of glass fiber tube is very wide, including electrical insulation, automotive industry, aerospace, industrial machinery, transportation system, marine industry, fire safety, thermal insulation, valve accessories, energy industry and other industries. It is mainly used in wiring harnesses of various industries and power protection fields.
4. How to choose fiberglass sleeve
- Heat Resistance: Compared with acrylic fiberglass sleeve, silicone fiberglass sleeve can withstand sustained temperatures up to 260°C (500°F) or higher, and can withstand short-term exposure to higher temperatures. Acrylic fiberglass sleeve is typically 105°C (220°F) to 130°C (266°F), depending on the specific type of acrylic coating.
- Chemical Resistance: Silicone coatings have excellent resistance to a wide range of chemicals, including oils, fuels, solvents, and acids. Acrylic coatings generally have good chemical resistance, but may not withstand the wide range of chemicals that silicone coated tubing can.
- Abrasion Resistance: Silicone Coated: Typically has better abrasion resistance due to the toughness of the silicone rubber.
Acrylic Coated: May be more susceptible to abrasion and wear compared to silicone coated sleeve.
- Weatherability: Silicone Coated: Silicone is highly resistant to UV radiation and ozone, making it suitable for outdoor applications.
Acrylic Coated: Acrylic coatings also have good UV resistance and can be suitable for outdoor use, but they may not last as long as silicone in harsh environments.
- Applications: Silicone Coated: Commonly used in high-temperature and harsh chemical environments, such as automotive, aerospace, and industrial applications. Acrylic Coated: Often used in applications where the temperature is not as extreme, such as in the construction industry for insulating pipes and as a protective covering for wires in outdoor lighting and signage.
Combine the above information with the actual application of the product to select the most suitable solution for your product.
