Glass-Fiber Reinforced Plastic (GRP) Storage Tank Performance Features

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 it has a higher specific strength than 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 1.5~2.0, it is only 1/4~1/5 of carbon steel, yet its tensile strength is close to, or even exceeds, carbon steel, with a specific strength that compares favorably to advanced alloy steels.

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

3. Excellent electrical properties: Suitable for manufacturing insulators.

4. Excellent thermal properties: Glass fiber has a low thermal conductivity, ranging from 1.25 to 1.67 kJ/(m·h·K) at room temperature, which is only 1/100 to 1/1000 of that of metals, making it an excellent insulating material.

5. Superior Processability: Flexible in choosing molding processes based on product shape, technical requirements, and application; simple process allows for one-time molding, with pronounced economic benefits.
