Why PBO
Why choose a PBO felt pad
01
No graphite marks
Felt does not shed particles or scratch the profile the way graphite does.
02
Rated to 600°C
Standard PBO works up to 600°C, and premium PBO reaches 650°C.
03
Your layer split
Choose from five PBO and Kevlar splits, or a pad that is PBO all the way through.
Application
Where PBO felt pads go
PBO pads sit at the press exit, in place of high-purity graphite.
They also cover cooling table levels 1 and 2.
Where the table runs cooler, Kevlar or Nomex pads cost less.
Our factory
How we make PBO felt pads
01
PBO and Kevlar fibre
The working face is PBO fibre. The base is 100% Kevlar para-aramid.
PBO is the most heat-resistant fibre we use.
The Kevlar base carries the load, so the PBO face only has to take the heat.
02
Carding
Carding opens the fibre and combs out impurities and short lint.
We control temperature and humidity so the web stays even.
An even web is what keeps the finished felt the same thickness from edge to edge.
03
Web laying and needling
The web is cross-laid in layers to the weight you need.
Needle punching then locks the fibre onto the base cloth.
The barbed needles pull fibre through the layers, so the felt holds together without glue.
04
Resin treatment
Resin grades run from R0 (no resin) to R3 (rigid).
Resin adds wear resistance and stops aluminium swarf sticking to the felt.
Tell us how abrasive the position is and we will suggest the grade.
05
Cutting
Each pad is cut to your width and length.
Edges come out clean, with no loose fibre.
Pads are cut from one piece, so there is no seam across the working face.
06
Needle check
Every finished piece passes through a metal detector.
No broken needle leaves the factory inside the felt.
A broken needle tip left in the felt would mark your rollers or your product.
