Ideal Filaments for Panel Glass Cleaning and Polishing Brushes

In the cleaning and polishing of panel glass, the characteristics of plastic filaments—specifically PA612, PA66, and PBT—directly impact efficiency and quality. This guide outlines the core properties and applications of these materials to help you make informed choices.

Core Material Characteristics and Applications

1. PA612

1)Shore Hardness: 80-90A

2)Characteristics: Soft and flexible with excellent chemical resistance.

3)Applications: Ideal for cleaning precision glass (such as smartphone screens and camera lenses), as it prevents scratches on nano coatings.

2. PA66

1)Hardness: 90-100A

2)Characteristics: Wear-resistant, fatigue-resistant, and capable of withstanding temperatures up to 150℃.

3)Applications: Suitable for ordinary glass scratch repair and removing grease in production lines.

3. PBT

1)Flexural Strength: 120MPa

2)Characteristics: High rigidity with a water absorption rate of less than 0.1%.

3)Applications: Best for deep polishing (like chamfering LCD substrates) and removing stubborn stains.

Selection Method

l  Determine Glass Type

Precision Screens: Use PA612.

Industrial Glass: Choose PA66 or PBT.

l  Assess Dirt Levels

Light Dirt: Opt for a soft brush (PA612).

Scratches: Select a hard brush (PA66 or PBT).

l  Evaluate Process Requirements

Cleaning: Focus on softness.

Polishing: Prioritize wear resistance.

l  Consider Cost Efficiency

For frequent use, select PBT or PA66 to optimize performance and longevity.
