Polyester (PET) Filter Fabric

The workhorse of industrial filtration. Polyester delivers the highest tensile strength and dimensional stability of all standard filter polymers, with continuous temperature resistance up to 150 °C.

Material Properties

High Temperature Resistance

Continuous operation up to 150 °C — the highest among standard filter polymers. Ideal for hot process streams.

Excellent Mechanical Strength

Superior tensile strength and dimensional stability under sustained pressure. Minimal elongation even after extended use.

Abrasion Resistance

Outstanding resistance to mechanical wear. First choice for mining, mineral processing, and other abrasive slurries.

Chemical Resistance

Good resistance to most acids at moderate concentrations. Moderate resistance to alkalis (pH 2–10). Not suitable for strong alkalis.

Low Moisture Absorption

PET absorbs minimal water (≤ 0.4%), ensuring consistent filtration performance and fast drying of retained filter cakes.

FDA Grades Available

Food-contact compliant PET filter fabrics available for edible oil, sugar, starch, and other food processing applications.
