High-performance polymers for the chemical industry: guaranteed strength and inertness

An industry exposed to the most aggressive environments

Chemical processes - in fine chemicals, pharmaceuticals, petrochemicals or surface treatment - expose materials to aggressive environments: acids, solvents, high temperatures, pressure, abrasion. High-performance polymers (HPPs) stand out for their chemical inertness, mechanical stability and durability in harsh environments.

DEMGY supports chemical manufacturers with injected, machined or printed HPP components, adapted to the extreme conditions of production units.

Pourquoi les HPP dans les procédés chimiques ?

Excellent chemical resistance (fluorinated acids, concentrated bases)
Temperature resistance up to 260°C
Inertia and mechanical stability in continuous operation
Low friction, no corrosion
ATEX / ISO 14644 cleanroom compatibility

Examples of applications in the chemical industry

Seals, flanges and valve seats in PTFE or PFA

Outstanding chemical inertia
Suitable for use with fluorinated acids and concentrated bases
Low friction, excellent sealing

Lining of equipment or PVDF or PEEK linings

Internal lining of tanks, pumps and heat exchangers
Pressure and corrosion resistance
Longer service life than metals

Dosing or filtration components

Filter housings in PCTFE (cryo compatibility)
Pump parts in PEEK GF (mechanical resistance + aggressive products)
Process connectors in PPS (high rigidity)
