Use:
Asbestos-free compression gasket 8700 is used for processes requiring neoprene rubber (CR) as a cement (e.g. freezing process) High performance gasket material.
Advantages:
1. It is our most suitable product for wine style HVAC OEM applications
2. It can achieve tight seal in the combustion of refrigerant and oil
Ingredients:
Asbestos-free compression gasket 8700 contains high strength aramid and inorganic fibers, and its cement is high quality neoprene rubber.
Viscosity resistance:
All compression pad materials have done a great deal of work in developing bond release with superior anti-viscosity properties. All  compression gasket materials were successful
Military standard MIL-G-24696B366° F/48hrs naval installations were tested for resistance to adhesion.

Note:
ASTM standard performance is measured at root plate thickness of 1/16 inch, but ASTM F38 is measured at plate thickness of 1/32 inch. These properties are for general reference only and cannot be used as a basis for acceptance or rejection. The data listed in this table are within the normal range of product performance and should not be used to prepare technical specifications or solely as a basis for design.
* Used when nominal pressure is above Class300. Please consult the representative office.
