APPLICATIONS
	Bearing seals, polishing, printing, wick lubrication and precision uses where a dense highgrade felt with max. durability is required.	Automotive, aircraft and machine components and similar to 16RI and 2 where slightly lower density and quality is acceptable.	Lubricators, wipers, shock dampeners and uses where a durable resilient felt is required.	Dust Shields, oil and grease containers; similar to 12R1 and 2 where a lower grade may be used.	Fluid storage and delivery, resilient padding, plug filters for gas and air.

 

Indicates grades to which designated fabricating method applies. (1)     Color available on special order. (2)     Thermal and acoustical felts blended with Kapok fiber have tested values of 0.21 K factor and 0.80 sound absorption coefficient at 512 cps for 1" thicknesses of 3.2 lbs. per sq. yd. weight. Note: Specification or test values given are results obtained by ASTM D-461 Methods of Test.

(3)     COF is dependent upon the condition of the contact surface, but is subject to moderate control by altering the surface finish of the felt. (4)     Up to 85% vibration absorption under appropriate design conditions. (5)     For any quality level, abrasion resistance increases with density.
