Chemical Resistance PE

Quick check of PE pipe chemical resistance with simplified rating and common name search.

Chemical Resistance PE

CAS No.:

Concentration range	Temperature (°C)	PE Rating

Permeation & Diffusion

Even with a suitable rating, media can diffuse through PE walls (permeation). This can cause odor transfer, taste impact or boundary-zone exposure.

Pressure, temperature and exposure time jointly affect suitability. For PE pipes, nominal pressure (PN) is referenced at 20 °C.

Low: up to approx. 10%, Medium: approx. 10-50%, High: above approx. 50% or concentrated/pure.

Suitable

Conditionally suitable

Not suitable

Simplified presentation for initial assessment. Project-specific boundary conditions are always decisive.

Background

ChemCheck provides a simplified first assessment of PE piping chemical resistance. Concentrations in the result table are grouped into three bands only: low, medium, and high. Temperatures are displayed only at 20 °C and 40 °C.

Rating Levels

Rating	Meaning	Recommendation
Suitable	Material behaviour is generally uncritical in typical use	Usually applicable
Conditionally suitable	Material can be affected depending on boundary conditions	Case-by-case technical check recommended
Not suitable	Significant material impact is expected	Avoid use

Key Influencing Factors

Concentration: Higher concentrations increase the load on the material.
Temperature: Rising temperature accelerates diffusion and swelling.
Duration of exposure: Longer exposure can increase material stress.
Pressure/temperature/time: These three factors always interact and must be assessed together.
Nominal pressure for PE: The nominal pressure class (PN) for PE pipes refers to 20 °C.
Stress: Under mechanical stress, resistance may decrease (environmental stress cracking).

Note: This quick check is for guidance only. Permeation and diffusion must be assessed project-specifically and considered by the responsible project office in the design.
