PVDF Series ｜ Chemical & Corrosion-Resistant Plastic Screws for Process Applications
🌟 Key Takeaways
- PVDF Series is a plastic screw series made from PVDF (Polyvinylidene Fluoride)
- Supports continuous operating temperatures up to approximately 140°C (284°F)
- Excellent chemical resistance, corrosion resistance, low water absorption, and chemical stability
- Flame-retardant performance equivalent to UL94 V-0
- Ideal for chemical processing, semiconductor, battery systems, water treatment, and process equipment
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
In environments continuously exposed to chemicals and liquids, the material selection of fastening components has a decisive impact on equipment reliability and service life.
The PVDF Series is a non-metal fastener series designed for long-term stable use in environments where metal fasteners corrode and general plastics degrade rapidly.
🔷 What Is the PVDF Series
Within the non-metal fastener lineup of Nippon Chemical Screw Co., Ltd., the PVDF Series is a material series specifically optimized for chemical- and corrosion-resistant applications.
PVDF (Polyvinylidene Fluoride) is a fluoropolymer known for its exceptional chemical stability and corrosion resistance.
As a result, the PVDF Series is widely adopted as a critical fastening solution in process industries where chemical exposure is unavoidable.
🔷 When Chemicals and Liquids Define Design Requirements
In the following environments, degradation of fastening components can lead to serious equipment issues:
- Contact with acids, alkalis, and various chemicals
- High-humidity and liquid-exposed conditions
- Loss of fastening force due to corrosion
The PVDF Series helps suppress corrosion and performance degradation,
reducing downtime risk and supporting stable system operation.
🔷 Key Features of the PVDF Series
Based on material data and technical documentation:
- Excellent chemical resistance : Compatible with acids, alkalis, and a wide range of chemicals
- High corrosion resistance : Ideal for wet environments and chemical processing lines
- Low water absorption : Minimizes dimensional change and material degradation
- Hydrolysis resistance : Maintains stable performance in water and steam environments
- High chemical stability : Suitable for long-term use in process equipment
- Electrical insulation & non-magnetic properties
- Flame retardancy (UL94 V-0 equivalent)
🔹The PVDF Series is a plastic screw solution specifically designed for chemical- and corrosion-dominant environments.
🔷 Main Application Areas
🧪 Chemical & Process Industries
Used in chemical plants, piping systems, valves, and chemical fluid lines
where chemical resistance and corrosion resistance are critical.
🔋 Battery & Energy Equipment
Suitable for fastening points requiring chemical stability
in battery-related systems and energy equipment.
🔌 Semiconductor, Electrical & Electronics
Adopted in semiconductor manufacturing equipment, including wet processes,
where cleanliness, chemical stability, and electrical insulation are essential.
🚰 Water Treatment & Environmental Equipment
Used in water treatment systems and environmental facilities
where metal corrosion risk is high.
🏥 Medical & Research Equipment
Applied in medical devices, analytical instruments, and laboratory equipment
requiring non-metallic, chemical-resistant, and safe materials.
🔷 Suitable Usage Conditions for the PVDF Series
- Chemical and corrosive environments as primary design conditions
- Environments where metal fasteners are prone to rust or corrosion
- Applications where general plastics lack sufficient chemical resistance
- Process equipment requiring long-term stable operation
🔷 Next Step in Material Selection
When applications require higher temperature resistance or higher mechanical strength
in addition to chemical resistance,
super engineering plastics such as the PEEK Series are recommended as the next option.
📘 Summary
The PVDF Series is a process-industry-focused plastic screw series designed with chemical resistance and corrosion resistance as top priorities.
It provides reliable fastening solutions that support stable operation and extended service life in chemical processing, semiconductor, battery, and water treatment applications.
