SSI PTFE Cap

PTFE caps, or Polytetrafluoroethylene caps, are sealing solutions with exceptional chemical resistance, high-temperature stability, and non-reactive properties. Manufactured by Shree Shakti Industries (SSI), these caps are an ideal choice for laboratories and industries requiring reliable sealing for high-purity applications.

Why Choose SSI PTFE Caps?

SSI’s PTFE caps offer numerous advantages, such as chemical resistance to strong acids and solvents, temperature stability ranging from -200°C to +350°C, and inert, non-reactive properties that ensure the integrity of substances stored within. Their versatility makes them suitable for laboratory, pharmaceutical, environmental, and industrial uses.

Key Features and Benefits of PTFE Caps

Chemical Resistance

PTFE caps are highly resistant to corrosive chemicals, including strong acids, alkalis, and a wide range of solvents. This makes them ideal for use in environments where chemical stability and compatibility are paramount, such as laboratories and chemical manufacturing.

High-Temperature Resistance

These caps can endure extreme temperatures from -200°C to +350°C, which is crucial for applications requiring thermal stability and resistance to thermal degradation. They are suitable for both cryogenic environments and high-temperature processing.

Low Friction and Non-Stick Properties

The low friction coefficient of PTFE makes it an excellent choice for applications where a smooth, non-stick seal is necessary. This prevents substances from adhering to the cap, ensuring easy removal and reusability.

Inert and Non-Reactive Material

PTFE is a highly inert material, making SSI’s PTFE caps perfect for high-purity chemicals, pharmaceuticals, and diagnostic reagents. These caps do not react with the substances they seal, preserving the purity of the stored contents.

Moisture and Gas Barrier

PTFE caps provide an effective barrier against moisture and gas, ensuring that sensitive substances remain uncompromised. This property is especially beneficial for safely storing chemicals and environmental samples.

FDA, Food-Grade, and Laboratory Safety

SSI PTFE caps comply with FDA standards, making them suitable for food-grade, medical, and laboratory use. These caps are designed to meet stringent safety standards, ensuring safe and sterile storage.

Reusable and Autoclavable

These caps are designed to be reusable and can withstand repeated autoclaving without degrading. This feature is particularly useful in laboratory and medical settings where sterility is crucial.

Customization Options

SSI offers PTFE caps in various sizes, colours, and cap types, such as screw-on, snap-on, and vented caps. This customization ensures that the caps meet the specific needs of different applications.
