PTFE-lined bottle caps offer a versatile solution for sealing vials, bottles, and containers, with size options tailored to meet diverse application needs. These caps are available in a wide range of customizable sizes, from as small as 24 mm to as large as 414 mm, with 24 mm and 40 mm being among the most commonly used. Customization extends beyond size, allowing for specific liner materials, colors, and branding to suit unique requirements.
Key Points Explained:
-
Size Range of PTFE-Lined Bottle Caps
- The standard size range for ptfe lined cap spans from 24 mm to 414 mm, accommodating a variety of container openings.
- Common sizes like 24 mm and 40 mm are widely used for laboratory vials and small bottles, while larger sizes cater to industrial or bulk storage needs.
-
Customization Options
- Beyond standard sizes, manufacturers offer custom-molded or CNC-machined PTFE caps to fit unique container specifications.
- Additional customization includes liner materials (e.g., silicone, LDPE, or PTFE), colors, and branding, ensuring compatibility with specific chemical or aesthetic requirements.
-
Applications and Suitability
- Smaller caps (e.g., 24 mm) are ideal for laboratory vials, while mid-range sizes (e.g., 40 mm) suit bottles for pharmaceuticals or chemicals.
- Larger caps (up to 414 mm) are designed for industrial containers or bulk storage, providing secure sealing for volatile or sensitive contents.
-
Why PTFE Liners?
- PTFE (polytetrafluoroethylene) liners offer chemical resistance, non-reactivity, and durability, making them suitable for aggressive solvents or high-purity applications.
- Alternative liners (e.g., silicone or LDPE) may be chosen for flexibility or cost-efficiency, but PTFE remains the gold standard for inertness.
-
Procurement Considerations
- When selecting a size, consider the container’s neck diameter and threading to ensure a proper seal.
- For specialized needs, work with suppliers to confirm material compatibility (e.g., autoclave stability or UV resistance) and lead times for custom orders.
Whether for lab workflows or industrial processes, PTFE-lined caps combine precision engineering with material science to deliver reliable sealing solutions. How might your specific application influence the choice between standard and custom sizes?
