Technical documents and tools for OEM design engineers specifying ERECTA SWITCH products. Product family overviews, operating principles, application notes, design guides, contact protection references, and an interactive chemical compatibility chart — organized by type for fast access.
Look up answers directly, rather than downloading a document and hunting through it.
Published chemical-resistance data for 2,575 chemicals against all six ERECTA SWITCH wetted materials — PVDF (Kynar), polypropylene, acetal, titanium Grade 4, Viton (FKM) and EPDM — at 20, 60 and 90 °C. Searchable, browsable A–Z, and downloadable as a 63-page PDF. Reference data for your own assessment, not a suitability determination.
Every rating names the manufacturer who published it and the revision date of the document it came from — Arkema, Braskem, Celanese, Parker Hannifin and TIMET. Most compatibility charts do not tell you who said it, or when. It also shows the seal gate: a housing rated A is no use if the o-ring is not, and that is the answer that most often decides the specification.
General guidance for preliminary screening only — not a warranty, specification or application advice. Ratings are the manufacturers' own, from immersion of unstressed specimens in single pure reagents; real service rarely matches those conditions. NF means not found, not a pass. Verify suitability for your own application before specifying. Full terms on the chart page.
