Guide to Impact of Chemicals on EPDM Rubber
GUIDE TO THE IMPACT OF CHEMICALS ON EPDM RUBBER
This guide will help assess different chemicals’ impact on EPDM rubber. This data has been compiled from reputable sources and will be used solely as a guide in selecting EPDM or determining its durability and resistance to chemical exposure.
Before permanent installation, test the material with the chemicals and under the specific conditions in force in your application. Ratings of chemical behaviour listed in this chart apply to a 48-hour exposure period, and exposure beyond this timeframe may lead to different impacts. If your application is more rigorous, please request a sample to test against the chemicals.
Rubber Roofing Direct LTD does not warrant (express or implied) that the information in this chart is accurate or complete or that any material is suitable for any purpose.
- A = Excellent.
- B = Good. Minor Effect. Slight corrosion or discolouration.
- C = Fair. Moderate Effect. Not for constant use. Softening, loss of strength, and swelling are possible.
- D = Severe Effect, not recommended for ANY use.
- N/A = Information Not Available.

FAQS
Need some help or guidance? Here are the most common questions our customers ask us
Installing an EPDM flat roof rubber membrane is far easier than a traditional roof. When done correctly, a roof membrane can be expected to last in excess of 50 years. That’s why it’s the number one choice for homeowners. Click here for detailed instructions.
An EPDM rubber roof can be used for low-pitched roofs. Unlike other traditional roofing materials, the rubber membrane is incredibly versatile and easy to install on a wide range of surfaces and angles. Click here for more details.
EPDM flat roofing is becoming an increasingly popular roofing material for UK homeowners because it’s incredibly inexpensive to purchase, install and maintain over its lifetime, which can span decades. Click here for more details.
An EPDM rubber roof can be bonded to asphalt but this needs to be the FlexiProof Fleece-Backed. It cannot be bonded to uneven surfaces such as shingles as this hinders the membrane from successfully bonding onto the surface. Click here for more details.
