Dunrite Rubber

HeatKing Belts

Benefits
• Ideal for applications with constant material temperatures over 150°F (66°C).
• All-synthetic fabrics specially woven from polyester fibers for excellent dimensional stability. There is minimal strength loss or stretch in high temperatures.
• Highly resistant to chemicals and acids, even in hot environments.
• Low moisture absorption ensures reliable service in wet applications.
• Widths available to 60" (1500 mm).
• A wide range of FLEXKING® carcass types are available
HeatKing Belts
GRT HeatKing Belts utilize an all polyester belt carcass to prevent distortion in high heat applications. Using the proper Heat Resistant compound, they will give trouble free service in high heat applications up to and including 450 F.
