Classified into 3 types: Pure Wool Felt Pads, Synthetic Fiber Felt Pads, Self‑adhesive Felt Pads. Select by density and thickness. Custom cutting available for special‑shaped pieces, round discs and gaskets.

I. Comparison of Two Main Materials

1. Pure Wool Industrial Felt Pads (First choice for precision machinery)

Complies with Chinese standard FZ/T25001, wool content ≥95%. Excellent oil absorption, wear resistance and resilience, heat‑resistant. Ideal for oil seals, guide‑rail sealing and precision buffering.

Common grades:

• T112 Super‑fine White Wool Felt: Density 0.32‑0.65 g/cm³. For precision sealing, polishing, instrument liners.
• 112 Fine Wool Felt: Density 0.32‑0.40 g/cm³. General‑purpose mechanical oil seals, bearing oil‑storage pads.
• 122 Semi‑coarse Wool Felt: Density 0.24‑0.38 g/cm³. Ordinary shock absorption and dust‑proof gaskets.

Thickness: 1‑50 mm, popular sizes: 3/5/8/10/15/20 mm.

Higher density: firmer texture, better wear‑resistance & sealing performance, lower elasticity.

2. Polyester Synthetic Fiber Felt Pads (Economical grade, acid‑alkali resistant, non‑shrinking)

Polyester needle‑punched felt. Density 0.07‑0.80 g/cm³. Oil‑resistant, acid‑alkali resistant, mildew‑proof and cost‑effective. Suitable for general shock absorption, dust prevention, packaging and filtration. Not for high‑temperature precision oil‑seal applications.

II. Core Specifications

Standard sheet sizes: 1000×1000 mm, 1000×2000 mm Thickness tolerance: For density＞0.3 g/cm³, thickness 2.6‑25 mm, first‑grade product tolerance ±11%‑14%.

Available processing types: flat pads, round gaskets, special‑shape cut‑parts, self‑adhesive version, felt strips, oil‑seal felt rings. Adhesive options: 3M adhesive or ordinary pressure‑sensitive adhesive for direct mounting on equipment surfaces.

IV. Typical Application Scenarios

1. Mechanical sealing & oil‑seal pads: Motors, reducers, machine‑tool guide rails, bearing end covers. Adopt high‑density wool felt for oil storage, dust‑proof and oil‑leakage prevention.
2. Shock‑absorbing cushion pads: Equipment bases, hardware parts, electronic component liners. Use low‑density soft felt.
3. Oil‑absorbing filter pads: Hydraulic stations, oil‑polluted equipment. Wool felt for oil contamination adsorption.
4. Anti‑wear anti‑slip pads: Anti‑slip for metal workpiece processing, mold cushion blocks.
5. Insulation & heat‑insulation pads: Electrical equipment insulation, heat‑resistant liners for high‑temperature equipment.
