The difference between silicone corrugated tube and transparent silicone tube

  Silicone bellows extrusion is currently mainly divided into extrusion process and liquid injection process in the market, and our company currently adopts dual-die extrusion process. It is similar to the transparent silicone tube, both of which are made of biocompatible silicone raw materials. The transparent silicone tube can basically be delivered to the customer after being extruded. Both are silicone corrugated tubes, which are more difficult to manufacture. Big, first it belongs to special extrusion and is divided into two die heads, the first die head extrudes the inner tube (the speed should be controlled to be consistent, otherwise the outer wall spacing will be too large, and the products produced are unqualified products) The second die is to extrude the outer wall of the silicone corrugated tube (this die needs to be rotated and extruded faster than the first die).
  Silicone corrugated tubes and transparent silicone tubes are used in the same category of food respiratory drainage, and general customer requirements must reach FDA and LFGB levels. Silicone bellows are mostly used in ventilators, anesthesia machines, etc. Transparent silicone tubes are mostly used in drainage pipes. The bellows are mainly used to discharge oxygen or exhaust gas, etc., and are a kind of auxiliary breathing pipeline equipment.
  Silicone corrugated tube has very good transparency (especially the liquid injection process, everyone has seen the baby bottle nipple, the two materials are the same), and has very good anti-yellowing property because the silicone corrugated tube is not a disposable product, It involves secondary recycling, so manufacturers use better-quality gas-phase adhesives during production. At present, most manufacturers of silicone raw materials used in silicone bellows use materials that can pass biocompatibility testing. After all, most of these products are used in medical treatment. Manufacturers dare not be sloppy.
  Silicone bellows can be produced with a variety of joint snaps, flexible and diversified. At present, the market is divided into small-diameter bellows, medium and large-diameter bellows, etc. Each specification has different usage methods and application fields. Most of them are auxiliary breathing pipelines such as ventilators and anesthesia machines, while small diameters are mostly used for air guidance inside industrial machinery products. Our company is a professional manufacturer, production and sales of silicone bellows, and can open molds to customize special types of bellows. Our company can also customize a variety of silicone braided tubes and silicone pressure-resistant tubes .
