Performance Characteristics of Glass Fiber Reinforced Plastic Storage Tanks

Physical Properties: The specific gravity of glass fiber reinforced plastic (GFRP) is typically 1.8-2.1, which is 1/4 to 1/5 of steel, and its specific strength is higher than that of steel, cast iron, and plastic. The coefficient of thermal expansion of GFRP is roughly equivalent to that of steel, while its thermal conductivity is only 0.5% of steel's.

Fiberglass storage tanks possess the following characteristics:

1. Lightweight and High-Strength: With a relative density between 1.5 to 2.0, it is only 1/4 to 1/5 of carbon steel, yet its tensile strength is nearly equal, or even exceeds, carbon steel, and its specific strength can rival that of high-grade alloy steel.

2. Excellent Corrosion Resistance: Offers good resistance to atmospheric conditions, water, and general concentrations of acids, alkalis, salts, as well as various oils and solvents.

3. Excellent electrical properties: Suitable for manufacturing insulators.

4. Excellent thermal performance: The thermal conductivity of glass fiber reinforced plastic is low, at 1.25~1.67 kJ/(m·h·K) at room temperature, which is only 1/100 to 1/1000 of that of metal, making it an excellent insulating material.

5. Excellent Processability: Can flexibly select molding processes based on the product's shape, technical requirements, and application; simple process, capable of one-time molding, with significant economic benefits.
