Twisted and baked glass fiber media string wound filter used for chemical filtration
3F’s glass fiber string wound filter is designed technically for chemical filtration, such as PET fusant, PU, UPR, etching solution, etc. in order to meet these special chemical filtration demands, all our glass fiber material is baked at first, to remove moisture inside, then twisted and weaved into threads before wound into a filter element.
This two extra processing steps make the filter element a. form gradient inner structure which increase its pollutant-holding capability as well as flow rate, b. decrease its fiber dropping possibly, in some fine chemistry field, outcome product could also be possibly contaminated by filter media fiber dropping or separate out. So 3F add this two extra steps to make the filter element be more suitable for chemical filtration use.

Features & Benefits
- High Dirt-Holding Capability: Gradient filter media structure, deep filtration, the dirt-holding capability is 3-5 times that of generic glass fiber filter
- Chemical Stability: Resist to PH 1-14, suitable for acetone, DMF, etc.
- Accurate Filtration: To achieve gradient filtration by adjusting yarn twist, in consideration of both removal rating and flow rate
- High Temperature Resistant: <=200℃, like 180℃ is required for processing PET
Application
By virtue of high precision, anti-corrosion and high temeprature resistance, our glass fiber string wound filter is widely applied to industries as below:
- Polymer Materials: PET, PP, PE, PA fusant filtration
- Resin Products: UPR, epoxide resin filtration, to remove mechanical impurities
- Paints & Inks: remove paints lump, metal oxide, carbon black, etc.
- Glue & Sealant: PU adhesive, remove isocyanate particles, and other coarse particles
- Fine Chemistry: medical intermediate, electronic chemicals like etching solution
