Shower hose purchase points

1, the shower hose is also known as the shower hose, it is the link between the handheld shower and the faucet. The general shower hose is made of EPDM inner tube, high temperature resistant nylon core and 304 stainless steel outer tube, the nut is made of cast copper and the gasket is made of nitrile rubber (NBR). EPDM rubber belongs to the copolymer, ethylene, propylene burn and non-co-choked diolefin by the solution co-polymerization of rubber.
2, first of all, aging resistance, resistance to hot water performance is quite good, EPDM has excellent weather resistance, ozone resistance, acid and alkali resistance, and in 125 ° C superheated water immersion for 15 months, the mechanical properties of change is very small, volume expansion rate of only 0.3%. Shower due to the need for long-term hot water flow through, so the use of EPDM as a hose is the best material.
3, the second is the elasticity, we all know that when using hand-held shower needs to keep stretching to rinse the body, and EPDM molecular chain can be maintained in a wide range of flexibility, in low position can still be maintained, so this is one of the main reasons designers choose EPDM.
