SPG: waterjet cutting, gaskets, seals and packings manufacturers
Flexitallic Sigma is a PTFE based group of products capable of sealing chemicals right across the 0-14pH range, at temperatures from cryogenic to 260°C and at pressures from 8.5 Mpa down to vacuum. Flexitallic Sigma is typified by low creep, sustained service capability and robustness and has numerous advantages over many alternatives including pure and filled PTFE and envelope gaskets.
The sigma range of products has been engineered to be user friendly -
• Materials can be cut easily using conventional tools and techniques.
• Complex geometric shapes can be accommodated, including narrow sections.
• Excellent dimensional stability.
• Gaskets are easy to install and remove.
• All products are non-toxic.
