1. Polytetrafluoroethylene and high quality silicone rubber or super pure silica gel are used as raw materials to ensure that the gasket is non-toxic.
2. The polytetrafluoroethylene film and silicon rubber or silica gel bond are used together to maintain the excellent properties of the two materials, and the polytetrafluoroethylene contact reagents of the composite septum have good chemical inertness, which can withstand acid, alkali resistance, temperature resistance and viscosity resistance, even in high temperature with concentrated acid, strong alkali or strong. The oxidant also does not work, and the elasticity of silicone rubber or silica gel can ensure the sealing performance.
3. No adhesive bonding process, without adhesive, the cushion keeps the fine rebound performance of silicone rubber or silica gel, softer than the adhesive technology, and can provide better protection for the needle of the automatic injector.
