Polyester felt can be produced by ordinary staple scrim or high strength filament scrim, due to the customer demands,weight ranges from 350 g/m2 to 800 g/m2.
1. working temperature: no higher than 150 degree celsius
2. specialties: puffy fiber structure & high air permeability & repeat dust caption feature & better dust holding capacity; low fiber loss & no liquid contamination, long durability, low filtration resistance & liquid pressure dropping.
3. techiniques used: needle punching & singing & press polish technique.
4. width: dominated by customers within 2.2m
Applications:
Chemical processing:dryers in the pigment,plastic and catalyst industries
Minerals processing:dryers and finish mills in the cement industry
Metal processing:process collectors in the lead,primary base metal,and foundry industries
