Will a Concrete Hose Age After a Certain Time
Ordinary PVC layflat hoses often stick at high temperatures. While the reason lies in their material. PVC relies on plasticizers to stay flexible. When temperatures rise, these plasticizers migrate to the hose surface. This migration creates a sticky film that can make the PVC lay flat hose adhere to itself, equipment, or other surfaces.
Critical Temperature Thresholds
Most PVC layflat hoses have a working temperature limit of 65℃. Beyond this, the hose softens rapidly. At 80℃, it loses mechanical strength and becomes highly prone to sticking . For example, if used to transfer hot water above 65℃, the layflat hose may fuse at folded points during storage.
Some specialized layflat water hoses (like high temperature resistant models) handle up to 105℃ (160℃ briefly). But these are not standard. Always check the manufacturer’s specs for your hose.
How to Prevent Sticking
First, avoid high-temperature environments—keep the PVC layflat hose away from heat sources like engines or direct sunlight. Second, store it properly: maintain 10–55℃ storage temps and keep it dry. If sticking occurs, wipe the surface with a clean cloth (avoid harsh chemicals) . For high-heat tasks, replace standard flat hoses with heat-resistant alternatives like rubber hoses .
