What is SAE FA-1 Synthetic-Wool Blend Felt?
SAE FA-1 Synthetic-Wool Blend Felt is a wool/synthetic-fiber blended felt to SAE J314, about 0.30 g/cm³ with 1.4 MPa tensile strength and 45 % elongation, giving better chemical resistance (corrosion resistance score 55) than pure wool at similar density. It is used for oil seals, buffing and acoustic work and is supplied as sheet, roll, strip and die-cut parts in plain (PLAIN), oil (OIL), flame-retardant (FR) and resin-impregnated (RES) conditions. Maximum service temperature is about 110 °C with thermal conductivity of 0.052 W/m·K; the synthetic content lowers tensile strength relative to SAE F-1 wool felt, which remains the choice where firmness governs. SAE FA-1 Synthetic-Wool Blend Felt has a density of 0.3 g/cm³ (0.0108 lb/in³), lighter than 93% of natural material grades. SAE FA-1 Synthetic-Wool Blend Felt has a tensile strength of 1 MPa (0.203 ksi), weaker than 96% of natural material grades. Elongation at break is 45% and the elastic modulus is 0 GPa (5.8×10⁻⁴ Msi).

Working with SAE FA-1 Synthetic-Wool Blend Felt
Is SAE FA-1 Synthetic-Wool Blend Felt easy to machine?
Steel-rule die cutting, clicker press, knife or abrasive waterjet; avoid dry high-speed routing (fiber scorch and fuzzing).
Can SAE FA-1 Synthetic-Wool Blend Felt be welded?
Not weldable as such; high-synthetic blends can be ultrasonically or heat-bonded, otherwise adhesive-bond or sew.
Can SAE FA-1 Synthetic-Wool Blend Felt be formed, bent or molded?
Wet-and-press or steam-form into washers, cones and seals; recovers most thickness after compression unless resin-set.
SAE FA-1 Synthetic-Wool Blend Felt chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
