GENERAL PROPERTIES
CIP Industrial Composites are laminated plastic materials that are made by impregnating fabric with thermosetting resins. The physical and mechanical properties of all grades of CIP make them excellent bearing materials. CIP composites offer design engineers an attractive, low cost alternative to the traditional materials used throughout industry for bearings, wear pads and other components. CIP composites have only 1/6 the weight of steel, good dimensional stability and contain no harmful or toxic materials.
CIP Composite materials are an excellent replacement for bronze and brass: They are recommended for general purpose bearings, bushings, slide pads, and other mating surfaces where wear resistance and durability are important. These materials are also ideal for pivoting and sliding applications where thin wall bearings are required. CIP Composite bearing materials can be manufactured in a variety of non-standard shapes and sizes, and can be readily machined and installed like comparable metal products.
ADVANTAGES • Low maintenance, allows for reduction or elimination of wet/grease lubrication.
• Long life, wear resistant.
• Excellent dimensional stability in water, corrosive fluids and chemical solutions.
• Excellent mechanical strength.
• Excellent electrical insulation and non-magnetic series are available.
• Non-abrasive to mating surfaces.
• High load capacity and shock load resistant.
• Does not contain abrasive (calcium carbonate) fillers.
AVAILABLE CIP PRODUCT GRADES The following CIP Composite grades are available in machinable pre-molded sheet, rod and tube forms from Boedeker Plastics. All grades are also available with optional solid lubricant fillers (graphite, molybdenum disulfide, or PTFE) evenly dispersed throughout the material.
SERIES 100
Medium weave polyester fabric with excellent mechanical strength.
SERIES 200
Medium weave polyester fabric (100 series) cross woven with PTFE textile for a low coefficient of friction. For wall thicknesses over 1/4 inch, the material is wrapped with series 100 material.
SERIES 300
High temperature Nomex fabric that can operate into the 400° range while maintaining its high compressive strength.
SERIES 400
Medium weave fabric (100 series) cross woven with a PTFE textile for a low coefficient of friction in thin-wall bearings. No additional series wrap is used.
HYDRO
For use in water-based and submerged applications.
