Do You Know How to Select Industrial Plastic Brush Filaments?

When it comes to industrial brushes, the choice of filament material is crucial. This guide explores the characteristics of three major filament materials: Nylon 66, PS (Polystyrene), and PBT (Polybutylene Terephthalate), helping you make an informed decision based on your specific needs.

1. Nylon 66 Filaments Characteristics

• High Abrasion Resistance: Nylon 66 is known for its durability, making it ideal for metal grinding and deburring of castings.
• Temperature Resistance: It can withstand a temperature up to 203°F, suitable for various applications in the automotive, aerospace, and stone processing industries.

Applications:

It is the preferred choice for industries that require robust performance over extended periods.

2. PS (Polystyrene) Filaments Characteristics

• High Rigidity and Chemical Resistance: PS filaments are resistant to acids and bases, including hydrochloric acid, sulfuric acid, and strong alkalis.
• Cost-Effectiveness: Generally, PS is less expensive than Nylon 66, making it an attractive option for budget-conscious projects.

Applications:

PS filaments are ideal for cleaning chemical pipelines and electroplating equipment, where exposure to harsh chemicals is frequent. Their rigidity ensures effective performance in these demanding environments.

3. PBT (Polybutylene Terephthalate) Filaments Characteristics

• Ultra-Fine Tip Filaments: PBT filaments can be manufactured with ultra-fine tips (as small as 0.08mm), allowing them to reach deep into small crevices.
• Anti-Static and Fatigue Resistant: PBT is excellent for applications requiring precision dust removal, particularly in electronics and medical devices.

Applications:

PBT filaments are perfect for cleaning electronic components, medical instruments, and fuel injectors, where precision and anti-static properties are essential.

Key Selection Factors

When choosing the right filament for your industrial brush, consider the following four factors:

1.     Environment: Assess the temperature, humidity, and corrosiveness of the environment in which the brush will be used.

2.     Material of the Object: Understand the material that needs to be cleaned or processed to ensure compatibility with the filament.

3.     Functionality: Determine the primary function of the brush—whether it’s for grinding, cleaning, or other applications.

4.     Cost: Evaluate your budget while balancing quality and performance requirements.
