Thermofiber 4511

Industrial Parts  /  TF4511 Non-Scoring Heavy Duty Sheet Lining

THERMOFIBER 4511 is a non-scoring, graphitic brake and clutch friction composite especially designed to run against copper, as well as cast iron and steel surfaces where low coefficients are required. It is ideal for use in aluminum and glass factories or qany application which utilizes long run-out tables.

THERMOFIBER 4511 is resistant to fade and shows exceptional thermal stability, maintaining its friction level through the range of operating temperatures.

THERMOFIBER 4511 is available in sheet sizes up to 40” x 40” and is highly-machinable for special pieces and sizes.

AVAILABLE FORMS Flat Sheets, Special Molded Pieces
