Fiberglass Needle Felt

Brief Introduction

Fiberglass Needle Felt is a widely used filtration medium with reasonable structure and good performance, made of fiberglass, punched combed chopped fiberglass with needles, mechanically made fiberglass, fiberglass and screens gradually structured and fiber web reinforced,also a felted non-woven filtration material.

Not only featured with high temperature resistance, corrosion repellent, stable sized, tiny elongation shrinkage and high tensile strength, but also with filament,3D micro-hole structure, high porosity and tiny air filtration resistance, Fiberglass Needle Felt is a competitively high-speed, high-efficiency filter medium for high temperature filtration. Compared with other high temperature chemical fibre felt, it has more inexpensive price,higher temperature tolerance and higher running resistance.

Main Features

1. Excellent Thermal Insulation: based on physical principles, gas has small heat conducting rate and good thermal insulating materials usually get many air cavities inside.With innumerable tiny gases and irregular structured fiber, Fiberglass Needle punched felt is the excellent thermal insulation medium.Its heat conducting coefficient is 0.2～0.040kcal/mhr℃.
2. Fire Retardant: silicide is the most component of fiberglass(above 50%), fireproof, free deformation, free embrittlement and high temperature resistance up to 700℃.
3. Great Noise Absorption:when fiberglass gets invaded by sound wave, its energy will be massive absorbed because of the friction among fiber and air cavities of different sizes.
4. High Insulation:fiberglass is the best insulating medium as it with high temperature resistance, great mechanical properties and chemical stability.
5. High Corrosion Resistance:With strong acid and alkali resistance, fiberglass needle felt can reach a long life expectancy without any properties damaged.
6. Great Resilience: within countless fixed air cavities, fiberglass has great resilience.Vibration retardant and tensile strength up to 1.0kg.
7. Low Wet Absorption:wet absorption is 0.
8. Weightless And Soft: compared with other insulation materials, fiberglass is the lightest and softest medium. It can reduce the load of weight and vibration when applied on mechanism.
9. Minimum Construction: flexible sizes and customization accepted.

Applications

Fiberglass Needle Felt can be used in soundproof, noise absorption, vibration reduction, fire retardant in electromechanical, architecture, transportation and automotive industries and mainly used in filtration fields as high temperature gas filter. And widely applied in various bag filters for fume purification and dust recycling in carbon black, steel, nonferrous metals, chemicals and incineration industries.
