In the present paper we introduced how high modulus polypropylene helps an innovative design of utility tunnel up to 4000mm in diameter. High modulus polypropylene shows high modulus but still maintain reasonable flexibility so that tunnel and surrounding soil could form an integrated system, which means no force is...

The PE properties are obviously improved by crosslinking modified to TPEX, which can approach to that of PEX, while still remaining thermoplastic. It can be processed by the common forming method of thermoplastic; the products can be hot-melted and the scrap can be processed to be reused. The two-layer structure...

New generations of PE100 and PE4710 pressure pipe materials exhibit a superior balance of mechanical properties. The slow crack growth performance of these materials measured by traditional tests such as PENT and FNCT can exceed one year. Accelerated test methods, including strain hardening modulus, accelerated FNCT,...
