KLINGER® GRAPHITE LAMINATE SLS

KLINGER® GRAPHITE LAMINATE SLS

KLINGER® GRAPHITE LAMINATE SLS is a high-quality graphite laminate designed for use in extreme temperature and chemical conditions. The material consists of layers of expanded graphite bonded to a smooth 0.05 mm thick stainless steel 1.4401 insert. This sealing solution is ideal for applications requiring minimal gas emissions and for connections with weak flanges such as enameled and glass surfaces.

Advantages and Properties:
KLINGER® GRAPHITE LAMINATE SLS stands out for its excellent chemical resistance and high thermal stability up to 450°C. The special technology used to apply the adhesive layer allows to keep its graphite content below 1% by weight, ensuring even distribution and reliable sealing. The material is durable, flexible, and adapts to uneven surfaces, increasing its effectiveness in demanding industrial applications.

Applications:
KLINGER® GRAPHITE LAMINATE SLS is an ideal solution for high-temperature and chemically aggressive applications. It is used in:

• irregular flange connections
• sealing systems requiring high tightness
• level indicators and installations with aggressive media

Standard Plate Sizes:
Available formats: 1000 x 1000 mm, 2000 x 1000 mm
Thicknesses: 0.6 mm, 0.8 mm, 1.0 mm, 1.5 mm, 2.0 mm, 3.0 mm
Other dimensions and tolerances are available upon request

Certificates and Approvals:
KLINGER® SLS meets strict safety and quality standards and holds certifications:

• DIN-DVGW – confirmation of high-quality sealing
• Fire-Safe according to DIN EN ISO 10497 – fire resistance
• BAM tested – approval for use in the chemical industry

KLINGER® GRAPHITE LAMINATE SLS is a versatile and durable sealing material, providing maximum performance and reliability in the most demanding operating conditions.
