Transparent bellows are mainly divided into small household appliances and one of the components of rehabilitation equipment, which either play the role of drainage or conduction of gas. The transparent silicone corrugated pipe has a smaller diameter and is mostly used in water dispensers, coffee machines, etc., because the transparent silicone corrugated pipe is wrapped with a winding strip to strengthen its bending radius (not easy to bend) while maintaining flexibility. Water or liquid is not easy to bend in half when passing through the pipeline, and the transparent silicone bellows can pass FDA, LFGB, NSF and other environmental protection grades.
