Raw carbon, thermoforming, and where spin actually comes from

Why an unfinished face grips the ball, what thermoforming does that cold pressing does not, and which claims to ignore.

Diagram comparing a raw unfinished paddle face with a sealed face

Paddle marketing leans hard on two words: raw carbon and thermoformed. Both describe real things. Neither means quite what the packaging implies.

The short version
  • "Raw" is not a grade of carbon. It means the face has no finish coat, so the weave itself grips the ball.
  • The benefit is durability of texture, not more spin on day one. Paint wears smooth long before carbon does.
  • Thermoforming is a build method, not a performance feature. It stiffens the perimeter and removes the glue line that usually fails.
  • Percentage spin and power claims are marketing. No standard test produces them.

Raw carbon means unfinished, not special carbon

"Raw" does not describe a grade of carbon fibre. It describes the absence of a finish coat. A conventional paddle face is painted or clear-coated; a raw carbon face leaves the woven fibre exposed.

That matters because spin comes from friction between the ball and the face. The texture of the weave itself grips the ball. A painted face relies on the paint for texture, and paint wears smooth long before the carbon underneath would.

How face texture changes what happens to the ball Two panels. On the left an unfinished face is drawn as a jagged surface profile with the ball rotating away from it. On the right a sealed face is drawn as a flat line with the ball sliding straight off. Both profiles are exaggerated for clarity.Raw, unfinished facePeaks bite the ball and drag it across the face.rotatesSurface profile, greatly exaggeratedSealed or painted faceThe ball slides; less of the swing turns into rotation.slidesSurface profile, greatly exaggerated
Friction is the whole mechanism. A textured face catches the ball and drags it across the surface, turning part of your swing into rotation. A slick face lets it slide, and that energy stays as forward speed instead. Surface profiles are greatly exaggerated — the real difference is measured in microns.

So the practical benefit of a raw face is not more spin on day one — it is that the texture is the material rather than a coating, so it lasts longer before going slick.

What T700 actually is

T700 is a standard carbon fibre designation describing tensile strength. It is genuinely common in paddle faces and it is a real specification, but it is not exotic and it is not a performance guarantee. Nearly every mid-range paddle claims it. Treat it as a baseline, not a differentiator.

Thermoforming is a construction method, not a feature

A cold-pressed paddle is assembled from a face, a core and an edge guard glued together. A thermoformed paddle is heated and pressed as one piece, usually with foam injected around the perimeter and the edge sealed.

Cold-pressed Thermoformed
Assembly Face, core and edge guard bonded together Heated and pressed as one piece, edge sealed
Perimeter Softer; off-centre hits twist the face more Stiffer, often foam-injected; wider usable area
Common failure Delamination at the glued edge No edge glue line to fail
Feel More flex at contact; softer Firmer and more direct; some players read it as harsh

Two things follow. First, the perimeter is stiffer, which widens the usable area of the face — off-centre hits twist the paddle less. Second, there is no glue line at the edge to fail, which is where cold-pressed paddles most often delaminate.

The trade is feel. Coming from a soft cold-pressed paddle, expect noticeably less flex at contact.

Texture wears, and how you treat it decides how fast

Whatever the face is made of, spin degrades as the texture polishes flat. The main culprit is court grit ground into the surface. Wiping the face after outdoor sessions genuinely extends its life; leaving it dirty genuinely shortens it.

Coarser faces bite harder and wear faster. If you play mostly on rough outdoor courts and want the texture to last a season, a moderately textured raw face will outlast an aggressively gritty one.

Claims worth ignoring

Percentage figures with no test behind them — "40% more spin", "30% more power" — are not measurements. No standard test produces them, and no two manufacturers would run the same one.

What we do about it

We do not repeat those numbers on product pages, even when the supplier supplies them. Where a manufacturer publishes a real specification — core thickness, face material, weight — the listing states it. Where they publish nothing, the listing says so rather than estimating.

Every paddle page states face material and construction the same way. Browse paddles

A simple raw-carbon paddle care routine

Cleaning is about removing loose court dust without coating, soaking, or polishing the face. Always follow the paddle manufacturer’s instructions when they are available.

  1. Start dry.
    Brush away loose dust with a clean, dry microfiber cloth after play.
  2. Use the right tool only on compatible faces.
    A paddle-face eraser is intended for unpainted raw-carbon or compatible textured faces. Do not use it on paint, graphics, or a surface the manufacturer excludes.
  3. Skip household chemicals.
    Avoid solvents, abrasive cleaners, and saturating the edge or face with water.
  4. Store it out of heat.
    Let the paddle dry before covering it and do not leave it in a hot vehicle.
Cleaning has a limit

Removing dirt can restore a clogged texture. It cannot rebuild a face that has physically worn smooth.
