Chemically resistant plastics for the process industry

In the chemical industry, materials are exposed to aggressive acids, bases, solvents, and high temperatures. Plastics are often the only material that can withstand these stresses without corroding. PlastShop delivers semi-finished products to plant builders, maintenance workshops, and process industries across the Nordic region. Our range covers everything from cost-effective PP to high-performance fluoroplastics like PVDF and PTFE.

Requirements and challenges

The material must withstand concentrated acids, bases, and solvents
Weldability for tanks, pipes, and containers
Temperature resistance at elevated process temperatures
Low permeability to prevent leakage
Certificates and traceability for safety-critical applications

Recommended materials

PVDF
Excellent chemical resistance, high purity. Tanks, pipes, and valves

PP-H / PP-C
Cost-effective, good chemical resistance. Tanks and piping systems

PE-HD / PE-100
Broad chemical resistance, weldable. Tanks and containers

PTFE
Universal chemical resistance. Seals, gaskets, and linings

ECTFE
Fluoroplastic with better mechanical properties than PTFE

PVC-U / PVC-C
Flame-retardant, chemically resistant. Ventilation and flue gas cleaning

Common applications

Process tanks and containers

PP, PE, and PVDF for storage and transportation of aggressive chemicals. Welded constructions with full traceability.

Piping systems and valves

PP, PVDF, and PVC for chemically resistant piping systems. Welded or flanged.

Corrosion protection and linings

PTFE, ECTFE, and PVDF as linings in metal tanks and pipes to protect against corrosion.

Ventilation and flue gas cleaning

PVC and PP for ventilation channels, scrubbers, and flue gas cleaning.

Why choose plastic?

Plastics do not corrode, unlike metal. In the chemical process industry, this means a longer lifespan, lower maintenance costs, and higher safety. Plastics are also lighter than metal, which simplifies installation and reduces the load on supporting structures. With the right material selection, plastics can handle most chemicals found in the process industry.
