Polyester Canvas Conveyor Belt
The polyester conveyor belt is also called EP conveyor belt. It's framework material is the polyester canvas interwoven with meridian terylene and latitudinal polyamide fiber. It is characterized with excellent endurance, good water-resistance, no lowering of strength in humidity, mildew-proof, and high load of initial models. It is applicable to convey materials in medium and long distance, with high-load, and at high speed.
