ZI-207 SW Gasket


SW Mineral Wool Gasket

The SW mineral wool is a self-adhesive, asbestos-free, high-temperature gasket. Thanks to their stability by high temperatures and their low caloric conductibility, the mineral fibers are a very good insulating material.

Self-adhesive, asbestos-free, high temperature mineral wool gasket (Rock wool).
Fiber-Ø: 5 to 6 μ, and 1,5 to 2,5 μ. Color: white.
Without halogen or polytetrafluorethylene. Contains some silicone (Fig. 01, Point 3).
Adhesive: Polyzol PSA SE-6101. Protective foil: PE film with silicone (*) layer.

(*) All self-adhesive products are usually fitted with a siliconized protective foil applied over the bounding surface. To install the product this foil must be removed: it is therefore not part of the product. The gasket material itself is silicon-free. It is possible however, that silicon traces are detected, as they can be transmitted to other parts during handling. An absolute silicon-free guarantee can, for that reason, not be given.

PWIS: please refer to the ZI-102

Operating Temperatures    
From –50°C to +200°C.

It is recommended to eventually replace the SW rock wool gasket on METU-SYSTEM 
products which have been subjected to operating temperatures above +200°C, as the gasket might crumble away.

Behavior in Fire    
Building Material Classification: no information
Fire resistance: no information
Smoke: no information

Food Industry    
Not suitable.

Outdoor Exposure
Weather and UV Resistances (DIN 53 386): The fibers are UV resistant.
Ozone resistance (DIN 53 509): Not tested

Mineral Oils and Fats: Not resistant
Organic Oils and Fats: Not resistant
Solvents: Not resistant

The resistances are valid for the fibers only, and not for the adhesives or other components. The adhesives has only a limited resistance against chemically. 

Oil Resistance
The fibers themselves are oil-resistant. The gasket will however absorb the oil, negatively influencing the adhesive properties of the bonding agent. The temperature resistances could also be affected.

General Information about Resistances to Chemicals
Chemicals and oils are available in very different qualities. Their properties vary depending on their concentration, operating temperatures, possible mix with other chemicals and the eventual presence of impurities. This is why gasket manufacturers only provide general information about the resistance of their products to various chemicals. In view of the above it is advisable that the client runs some tests in order to assess if the gaskets are suitable for the intended application. We regret not being able to provide more precise information.

Does not contain any substances (SVHC) which could be of concern according to the REACH extended list dated 13-01-2010. 

VDI 6022
Not conform.
