| Abstract: | A kind of speciality resin, denoted as EP1D30P, for hot water pipe was prepared with taking random copolymer of propylene as basic resin into which a home-made compound auxiliary agent was introduced. The analyses of macromolecular structure and performance as well as the test for tubing application of the speciality resin verify that all its physical properties and specifications satisfy the designed requirements, such as notch impact strength of 55.54 kJ/m^2 or higher and oxidation induction period equal to or longer than 113.5 minutes. In addition, the resin has preeminent processability and appearance eligible to manufacturing pipes, which successfully passed the 1 000-hour hydrostatic pressure test. |
