| ¡¡Product Characteristics |
 |
PE-RT pipe is a kind of MDPE with stable mechanical performance after copolymerization of monomer of ethene and octylene.
The special structure of ethene main chain and octylene short chain branch made the product possess excellent tenacity, stress cracking resistance, low temperature impact resistance and outsanding long-term hydraulic resistance of ethane, and heat resistance and creep resistance of octylene at the same time.
Adopting superior hot melting connection method, the product can be repaired through hot melting connection with a pipe when being damaged.
It possesses good flexibility, the pipe is easy to bend and convenient to construction, and its bend radius is small, which will not rebound after bending.
The raw material has creep destruction curve that is in compliance with the product standard, which is the only excellent variety that can be used as hot water pipe without crosslinking in PE at the present stage.
