Polyolefin composition with excellent colour and thermal stability as well as oxidation resistance for pipes |
摘要 |
The present invention relates to a polyolefin composition with increased resistance to discoloration and to oxidation as well as superior thermal stability and to a pipe or a fitting made of such a polyolefin composition. The composition comprises a polyolefin base resin (A), an antioxidant (B) having a chroman-6-ol structure, an antioxidant (C) having a phenolic structure and an antioxidant (D) having a diphosphite structure. The present invention further relates to the use of the polyolefin composition for the production of a pipe or a fitting and to the use of the polyolefin composition for increasing the lifetime of a pipe or fitting providing the polyolefin composition with resistance against degradation caused by oxidation and with thermal stability. |
