At present, the more common shower hoses on the market are made of PVC, rubber and steel wire. The steel wire has better resistance to bending and is not easily broken, which can increase the service life of the shower hose.
1. The shower hose is the link between the hand shower and the faucet. The general 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 silicone rubber. EPDM rubber is a copolymer. Ethylene, propylene, and non-conjugated diene are copolymerized by solution copolymerization. Then some friends have to ask, why use this rubber as a shower hose?
2. First of all, the aging resistance and super hot water resistance are quite good. EPDM has excellent weather resistance, ozone resistance, acid and alkali resistance and so on. After soaking in hot water at 125 ℃ for 15 months, the mechanical properties change little, and the volume is small. The expansion rate is only 0.3%. Shower hose requires long-term hot water flow, so EPDM is the best material.
3. The second is elasticity. We all know that when using a hand shower, we need to stretch constantly to rinse the body. The EPDM molecular chain can maintain compliance in a wide range and can be maintained in a low position, so this is also a design. One of the main reasons why authors choose EPDM.
