Specification review required: the legacy polyester-felt data below does not establish hot-melting machine specifications. Request the correct machine data sheet before selection.
polyester filter bag are made of 100% filament polyester fiber,after needle punched, singed heat set calender for the raw polyester filter felt material, then polyester filter felt can be sewn into polyester filter bags.
Feature:
1. Operation temperature 150 Deg c,
2. the max surge is 150 deg c.
3. Polyester media compatibility depends on chemical exposure, moisture and operating temperature.
4. Mean Air Permeability: 10-15 m3/m2/min@12.7mmH2O
5. Media selection and cost depend on the required specification and operating conditions.
Available Finish: singed,calendar,heat set PTFE membrane,W/O,anti-static treatment.
Advantage:
Legacy polyester media values list breaking elongation below 20% MD and 40% CMD and reference 130°C operation. Confirm the applicable media data sheet; these are not machine operating specifications.
