Reinforced Laminates

HPMS graphite laminate products include pure graphite laminated sheets and laminated graphite sheets reinforced with various inserts such as stainless steel, stainless steel tanged (perforated) sheet, or wire screen mesh. Excellent sealing material for gaskets.

These laminates have excellent mechanical strength and handleability, exhibit low creep relaxation, stable compressibility, and recovery characteristics. They are widely used to provide thin cross-section gaskets and are used for many high pressure industrial applications.
