Non Asbestos Cylinder Head Facing Material
Non Asbestos Cylinder Head Gasket Facing Material is engineered for reliable sealing performance in small engine, automotive, diesel engine and industrial cylinder head applications. Aeroflex HNA materials are asbestos-free facing sheets made with inorganic fillers encapsulated by NBR binder, making them suitable for combining with perforated metal cores in cylinder head gasket production. The range includes HNA-1000, HNA-2000, HNA-3000 and HNA-4000 grades, allowing buyers to compare density, recovery, compressibility, tensile strength and fluid resistance based on application requirements.
Why Choose This Material?
Choosing the right Non Asbestos Cylinder Head Gasket Facing Material helps reduce leakage risks, support temperature stability and improve compatibility with engine oils, fuels and coolant exposure. Aeroflex provides product data based on recognized ASTM test methods, including ASTM F-36 for compressibility and recovery, ASTM F-152 for tensile strength, ASTM F-146 for fluid resistance and ASTM F-495 for ignition loss. This helps OEMs, gasket converters and aftermarket manufacturers select the correct non asbestos gasket facing material with confidence. Non Asbestos Cylinder Head Gasket Facing Material is suitable for cylinder head gasket manufacturing where non asbestos composition, stable compression and consistent roll quality are required. Common applications include small engines, automotive engines, diesel engines, agricultural machinery, generators, compressors, pumps and heavy machinery. The material is designed for use with perforated metal core constructions and can be supplied in roll form for efficient gasket conversion, lamination, cutting and finishing processes.

Grade Selection Guide
HNA-1000 is a practical entry grade for small engine cylinder head applications where balanced compressibility and non asbestos safety are important. HNA-2000 and HNA-3000 offer higher recovery values for buyers comparing performance under engine fluids and compression load. HNA-4000 can be positioned for applications that require a different compressibility profile and grade-specific fluid resistance values. Buyers should select the final grade after reviewing operating temperature, fluid exposure, gasket design, metal core type and compression requirements.
