Chemical resistance of wiring trunkings, conduits and accessories made of hard PVC, PE, PA, PS, PP and PPE
Key:
# : These materials are resistant to chemical damage under normal installation conditions
o : The resistance of these materials to mechanical damage is only limited
x : These materials are not resistant to chemical damage under specified conditions
Abbreviations: PVC-polyvinylchloride, PE-polyethylene, PA-polyamide, PS-polystyrene (rigid Krasten), PP-polypropylen, PPE (PPO)-polyphenylenether (polyphenyl oxid).
