Glass fiber and aramid fiber composite needle felt

Aramid is a meta-aramid fiber which can withstand temperatures below 240 ° C under dry conditions. Hydrolysis occurs when there is moisture and chemicals. Aramid is a polycondensation polymer like polyester that will hydrolyze and only withstand much higher temperatures. Aramid is a filter used in high temperature applications where the polyester will be brittle and fail. Aramid has excellent flex resistance and wear resistance and is better than most synthetic fibers. Aramid fibers are non-thermoplastic and cannot be glazed, but special techniques can be used for singeing or other post-treatment.

Glass fiber has excellent properties of non-combustible, corrosion-resistant, high-temperature resistance, low moisture absorption and small elongation. It is not only ten times more powerful than bulk glass, but also far superior to other natural fibers, synthetic and various alloy materials, and is an ideal reinforcing material.

NASAVEL glass fiber and aramid fiber composite needle felt, its structural feature is that the composite fiber surface layer of glass fiber and aramid fiber is symmetrically bonded on both sides of the glass fiber base cloth. The composite needle felt has Excellent performance of high temperature and corrosion resistance, with working temperature 200-230℃ and extreme value 250℃, small shrinkage at high temperature. NASAVEL dust filter bags have very outstanding performance in various applications.
