Hello all!
In my hands i have a few pieces of PEx-c pipe (electron ray cross linked polyethylene), which have been part of a ring main tube of a drinking water circuit (hot water). The pipes where put in in 1984 and last year they cracked and - of course - started leaking. The pipes were replaced and the brittle stuff is on my desk now. These bits of pipe are so brittle they break easily and shatter when they fall onto a stone floor. The producer of the pipes says that "the temperature stabilizer" was "used up" prematurely. An immediate google tour did not help me on my questions:
- What are temperature stabilizers for PEx?
- How do they work?
- What could probably "use them up"? (no high temperature stresses
Anyone any ideas on this? Thanks in advance for any help!
