Product Structural Features

1. Excellent Heat Resistance
Reinforced polypropylene is a material made by adding glass fiber to pure PP, expanding its application range. Its enhanced heat resistance overcomes the inherent mechanical strength disadvantage of PP, while maintaining its excellent corrosion resistance and increasing its operating temperature.
2. High Mechanical Strength and Excellent Wear Resistance
Its strength, stiffness, hardness, and heat resistance surpass those of low-pressure polyethylene.
Its low linear expansion coefficient provides excellent acid, alkali, and heat resistance.
3. Excellent Impact Toughness
Molding Shrinkage: 1.0-2.5%, significantly reducing shrinkage and significantly improving stiffness. It offers excellent electrical properties and high-frequency insulation, unaffected by humidity.
4. Wide Range of Applications
FRPP, due to its low material cost, long service life, and easy installation, is widely used in piping systems for the chemical, chemical fiber, chlorine-alkali, dye, water supply and drainage, food, pharmaceutical, sewage treatment, and electrolysis industries.
