Felt Grade	Description	Color	Wool Content	Tensile Strength	Shore A Hardness	Compression for 10% Deflection, psi	Vibration	Abrasion
F1	High density felt for precision uses where maximum durability and resistance to wear are required.	White	95%	500	30-40	21	Superior	Superior
F2	High grade felt, less tensile strength than F-1.	Pink/Blk/Brown	90%	500	30-40	21	Superior	Superior
F3	High grade felt, less tensile strength than F-1, very similar to F-2 with less wool content.	Grey	85%	400	30-40	13	Superior	Superior
F5	High grade, medium density felt recommended for precision uses where resiliency and durability are important factors.	White	95%	400	20-30	6	Average	Average
F7	Medium density felt similar to F-5 and recommended for similar applications, but where slightly less durable material is permissable	Grey	80%	250	20-30	6	Average	Average
F10	High grade, medium low density felt, similar in quality to the F-5, but recommended for uses where abrasion and wear resistance are not important factors.	White	95%	225	15-25	4	Poor	Below Avg.
F11	Medium low density felts recommended for uses similar to those of F-10 where less durability can be tolerated.	Grey	87%	200	15-25	4	Poor	Below Avg.
F13	Low Density felt with a wide range of uses where resistance to abrasion, durability and wear are not important requirements.	Grey	75%	75	15-25	3	Poor	Below Avg.
F15	Very similar to F-13, but with slightly less wool.	Grey	55%	75	15-25	3	Poor	Below Avg.
F26	Low Density Felt recommended for non-mechanical applications when retained between two other materials.	Grey	45%	Not Rated	15-25	1	Not Recommended	Poor
