HAMAMAT

Very high load capacity resilient seating and damping material made from fibre reinforced Neoprene

Description
A very high strength, high stiffness resilient seating material particularly suited to very high load applications such as building structures.

Construction
A compression moulded material made up of high grade Chloroprene (CR) / Neoprene rubber reinforced with microscopic santoweb fibres to increase strength and stiffness.

Applications
Structural damping of very high load applications such as building structures as well as impact shock absorption of forging and forming machinery and forging anvil mats etc.

Other properties
Long Term: Excellent ozone and oil resistance, low creep
Working temperature range °C: - 30 to + 120
Standard Sheet Sizes 1000 x 500 mm, 500 x 500 mm
plus Strips and Pads according to customer requirements
