Good thermal stability and oxidation resistance
Good thermal stability and oxidation resistance, suitable for medium-temperature filtration scenarios.
Balanced temperature resistance, oxidation resistance and dimensional stability for neutral and weak-acid filtration.

Polyester (PET) filter press cloth is woven multifilament filter medium manufactured from polyester fiber with heat-set treatment. Distinguished from PP, nylon, monofilament cloth and needled filter felt, it delivers balanced performance in temperature resistance, oxidation resistance and dimensional stability. It is widely adopted for solid-liquid separation under neutral and weak acid conditions on plate and frame filter presses.

Good thermal stability and oxidation resistance, suitable for medium-temperature filtration scenarios.
Low thermal shrinkage after heat setting, stable size under continuous pressure.
Balanced tensile strength and moderate cost, cost-effective for general filtration conditions.
Uniform pore structure for stable particle interception and clear filtrate.
Good resistance to organic solvents, applicable for many chemical production processes.
