Physical and Chemical Properties
-
High Strength and Lightweight: Glass fiber is inherently strong and lightweight, and these properties are retained in the chopped strand mat while maintaining good flexibility.
-
High-Temperature Resistance and Fireproofing: As an inorganic material, glass fiber has excellent high-temperature and fire-resistant properties, with a melting point of up to 1500°C.
-
Chemical Resistance: It has good resistance to a variety of chemical substances and is suitable for chemical corrosion protection applications.
-
Electrical Insulation: It possesses excellent electrical insulation properties, making it suitable for electronic and electrical applications.
-
Low Water and Combustible Content: It has a low moisture content (≤0.2%) and low combustible content (1.8%-8.5%), ensuring stability during processing and use.
Processing and Application Characteristics
-
Uniform Distribution and Resin Affinity: The fibers are evenly distributed and have good compatibility with resins, allowing for quick resin absorption and reducing bubble formation.
-
Good Formability: Chopped strand mat is easy to process and has good moldability, making it suitable for complex shapes and surfaces. It can be used in various processes such as hand lay-up and compression molding.
-
High Transparency: During lamination, chopped strand mat can produce highly transparent products.
-
Low Resin Consumption: Due to its good resin affinity and uniform distribution, chopped strand mat can reduce the amount of resin required.
Application Fields
Glass fiber chopped strand mat is widely used in the following areas:
-
Automotive and Marine Manufacturing: For automotive interiors, boat hulls, and decks.
-
Construction and Building Materials: For flat roofs, drainage ditch linings, and tank coatings.
-
Chemical Corrosion Protection: For chemical pipelines, storage tanks, and other corrosion-resistant projects.
-
Electronics and Electrical: For electronic device casings and insulating materials.
-
Environmental Protection and Infrastructure: For environmental equipment, bridges, and other applications.
fiberglass chopped strand mat, with its excellent physical and chemical properties and good processing characteristics, has become an important reinforcement material and is widely used in many industries.
