Applications

Polymers are rapidly replacing metals and widely used in chemical plants due to unmatched corrosion resistance, cost savings, and longer service life. Demand surges for high-purity, chemically inert materials as industries shift toward aggressive solvents and acids.

Characteristics of Chemical Processing Applications:

✤ Extreme Aggression: Constant contact with acids (H₂SO₄, HCl), alkalis, solvents.

✤ High-Purity Needs: Zero contamination in pharma/food-grade processes.

✤ Thermal Stress: Temperatures from cryogenic (-40°C) to 150°C+.

✤ Safety Critical: Leak prevention in hazardous environments.

Materials must meet specific properties as below:

Critical Property Requirements:

✤ Chemical Resistance: Must pass ASTM D543 testing for target chemicals.

✤ Thermal Stability: No deformation at operating temps.

✤ Purity: USP Class VI/FDA compliance for pharma applications.

✤ Mechanical Strength: Resist cracking under pressure/vibration.

✤ Non-Contaminating: No leaching of additives.

Recommended Materials for Chemical Processing Applications:

✤ Containment: PP sheet-lined reaction tanks, PTFE-lined steel pipes

✤ Seals: FKM O-rings for acid pumps, PTFE valve stem packing

✤ Components: PEEK pump impellers, HDPE laboratory sinks

✤ Safety: FRP (epoxy glass) walkways, UHMWPE chute liners

✤ Electrical: Phenolic cotton terminal blocks in corrosive zones

✤ PEEK: Pump gears, sensor housings

✤ PTFE： Lined pipes, gaskets, labware

✤ PP: Chemical tanks, exhaust ducts

✤ HDPE: Pipe liners, drum containers

✤ PVC: Ventilation ducts, valves

✤ Rubber (FKM/EPDM): O-rings, expansion joints

✤ Epoxy Glass Sheets: Cable trays, transformer housings

✤ Phenolic Cotton Sheets: Switchgear panels
