Product Description
ISO9001 Certified EPDM/Fkm/Silicone/Rubber/NBR/metal Waterproof Rubber Moulding Parts Cups For Standard Masking Uses of Silicone Stoppers (Silicone Plugs/Caps)
Silicone stoppers (also known as silicone plugs or caps) are widely used across various industries due to their inherent properties: high-temperature resistance, corrosion resistance, excellent elasticity, superior sealing performance, and non-toxic, odorless composition. Their primary applications are categorized as follows:
I. Laboratory & Scientific Research
Container Sealing: Used for the temporary or long-term sealing of test tubes, flasks, reagent bottles, and petri dishes. They prevent solvent volatilization, contamination, and sample degradation, making them ideal for experiments requiring frequent access.
Instrument Accessories: Serve as interface seals for glass apparatus such as separatory funnels, condensers, and gas generators. Compared to traditional rubber stoppers, silicone offers superior chemical inertness and aging resistance while ensuring airtight connections across different bore sizes.
Sample Protection: Employed in storage and transportation to seal centrifuge tubes and cryovials, preventing leakage and cross-contamination. Medical-grade silicone meets sterile requirements for biological samples.
II. Industrial Manufacturing & Machinery ISO9001 Certified EPDM/Fkm/Silicone/Rubber/NBR/metal Waterproof Rubber Moulding Parts Cups For Standard Masking
Temporary Port Plugging: During machining, welding, painting, or maintenance, these stoppers block pipe ends, bolt holes, and process holes. They prevent the ingress of metal shavings, dust, paint, or coolants, protecting internal components from damage.
Fluid System Sealing: Utilized as auxiliary seals in hydraulic, pneumatic, and chemical piping systems. They can withstand specific pressures and temperature ranges (Standard silicone: approx. -40°C to 200°C; Specialty grades: up to 300°C+).
Mold Protection: Used in injection molding and die-casting to cover reserved holes or locating holes, preventing foreign matter from entering the mold cavity or release agents from seeping into non-working areas.
III. Medical & Healthcare ISO9001 Certified EPDM/Fkm/Silicone/Rubber/NBR/metal Waterproof Rubber Moulding Parts Cups For Standard Masking
Medical Device Components: Medical-grade silicone stoppers (compliant with ISO 10993 biocompatibility standards) are used for sealing IV bottles, blood collection tubes, and reagent vials. They are also used as temporary port covers on equipment like ventilators and can withstand autoclave sterilization.
Rehabilitation & Care: Soft, skin-friendly silicone plugs are used to cover fixation holes in wound dressings or serve as temporary seals in prosthetics and orthotics.
IV. Daily Life & Miscellaneous Applications
Household Protection: Used to cap unused holes in furniture (e.g., screw holes) or appliances, keeping out dust and improving aesthetics. Food-grade silicone is safe for use as replacement bungs for milk bottles and spice jars.
DIY & Crafts: Used in modeling and handicrafts to plug small part holes or as temporary fasteners due to their flexibility.
Automotive & Electronics Repair: Temporary plugs for automotive fuel lines or cooling system ports, as well as blocking screw holes in electronic enclosures during repair work.
Summary of Core Advantages
The key value of silicone stoppers lies in:
Adaptability: Excellent elasticity allows for a tight fit on irregular or varying bore sizes.
Durability: Resistant to extreme temperatures, aging, and most chemicals (superior to standard rubber).
Safety: Non-toxic and odorless; available in Food-Grade and Medical-Grade for sensitive applications.
Convenience: Reusable, removable, and leaves no residue (unlike paper or wooden plugs).
