All sizes of Telfon coated rubber stoppers
*The following content is generated by AI and is for reference only.
Overview
Telfon coated rubber stoppers consist of a resilient rubber core encapsulated in a Polytetrafluoroethylene (PTFE) layer. This composite design combines the sealing elasticity of elastomers with the chemical inertness and low friction coefficient of PTFE, manufactured via high-temperature sintering or dip-coating processes.
Application
- Pharmaceutical manufacturing: Vial sealing in sterile filling lines.
- Chemical processing: Valve isolation in corrosive acid/base transfer systems.
- Laboratory instrumentation: Sealing ports on glass reactors and chromatography columns.
- Food & Beverage: Closures for high-purity liquid dispensing equipment.
Precautions
- Operate within -100°C to +260°C temperature range.
- Maximum working pressure typically limited to 15 bar; avoid mechanical over-compression.
- Clean using non-abrasive solvents; inspect coating integrity before reuse.
