EPDM Strips & Square Profiles
- Product Details
Product Description
EPDM strips and square profiles are the most versatile sealing products: as simple geometric cross-sections they can be used universally — as shim strips, spacers, stop seals or compensation elements.
Available in Shore hardnesses from 40 to 80 Shore A, in dimensions from 2×2 mm to 50×50 mm, sold by the meter or cut to length. Self-adhesive versions on request.

- FAQ
Frequently Asked Questions
Which Shore hardness for which application?
Shore A 40: soft, easily compressible, for stop seals. Shore A 60: standard, universal. Shore A 80: firm, for load-bearing shims and spacers.
How does EPDM behave with oils?
EPDM is not oil-resistant. Mineral oils, fuels and greases cause EPDM to swell heavily. For oil-contacting applications we recommend NBR.
Is EPDM available in food-grade form?
Yes, in FDA 21 CFR and EU 1935/2004 compliant compounds — on request.
Can strips be supplied self-adhesive?
Yes, with an industrial acrylic adhesive layer on one or both sides. Bonds to metal, glass, plastic and painted surfaces.

Is EPDM available in food-grade form?
Yes, in FDA 21 CFR and EU 1935/2004 compliant compounds — on request.
What is the minimum order quantity?
Standard cross-sections from 1 linear meter. Custom cross-sections from approx. 100 linear meters.
