Description

Introduction

Key Features

>High-Temperature Resistance – Can withstand continuous temperatures up to 260°C (500°F), with short-term exposure up to 300°C (572°F).

>Excellent Chemical Resistance – Resists acids, alkalis, and oxidation, making it suitable for corrosive gas filtration.

>Low Thermal Shrinkage – Maintains dimensional stability under high temperatures.

>High Filtration Efficiency – Captures fine dust particles while maintaining good airflow.

>Good Mechanical Strength – Reinforced with PTFE or other coatings to enhance abrasion resistance and durability.

>Long Service Life – With proper coatings and treatment, fiberglass filter bags can last longer than synthetic fiber filter bags.

>Customizable Surface Treatments – Available with PTFE membranes, acid-resistant coatings, or graphite coatings to enhance performance in specific environments.
