PP screws are widely used in household and commercial water filtration systems, food and beverage production lines, chemical container accessories, and light-duty electronic housings. They are suitable for low to medium load applications.

With glass fiber (GF) reinforcement, PP+GF screws offer higher strength and better heat resistance. They are used in electrical control boxes, outdoor enclosures, chemical equipment brackets, and medium-load structural components.

• Standard PP: continuous use up to 90°C; short-term up to 100°C.
• PP+GF: continuous use up to 110°C; short-term up to 120°C. Better for environments with temperature fluctuations.

PP screws are resistant to most acids, bases, and salt solutions. They are not resistant to aromatic solvents (benzene, toluene, xylene) or chlorinated hydrocarbons (carbon tetrachloride, chloroform, trichloroethylene). Best suited for low-temperature chemical and outdoor water applications.

Slightly lower than standard PP, yet stable in most acidic, alkaline, and saline environments—suitable for water treatment and outdoor chemical equipment.

• PP: economical, lightweight, and resistant to most water treatment chemicals.
• PVDF: superior high-temperature performance and resistance to strong oxidizers and fluorides—suited for high-end or harsh environments.

Yes. PP screws have very low water absorption (<0.1%) and maintain dimensional stability under humidity. Not recommended for long-term high-pressure underwater structures.

Used in electronic control boxes, interior fasteners, and other non-load-bearing components, benefiting from lightweight and cost advantages.

In medium-load, corrosion-prone environments, PP+GF screws can replace certain metal fasteners while remaining significantly lighter.

PP+GF combines low weight, rigidity, and corrosion resistance. It does not rust and remains stable in rain, salt spray, and humid environments—ideal for outdoor enclosures, coastal facilities, and water treatment equipment.

• Standard PP screws: ~1/8–1/9 the weight of carbon steel screws.
• PP+GF screws: ~1/6 the weight of carbon steel screws.
This reduces structural weight while maintaining adequate strength, lowering transportation and installation costs.
