Rags,
You should know by now that I do my homework!
Rags, and Swishing8-10,
When I purchased my original Trizact pads and its CAB (different from sandpaper CAB)from Innovative Bowling, I got a chart from them indicating the approximate ranges of the green, blue, orange and white pads.
Here at ballreviews we have had many discussions over the past 2-3 years over why to use them, how to use them and how some people still believed in using plain sandpaper (no comment). Here is teh chart I got from Innovative:
Trizact Orange pad (A5 micron or 1000-2500 grit {roughly 1200 grit})
Trizact Blue pad (A10 micron or 500-1000 grit {roughly 600 grit})
Trizact Green pad (A35 micron or 180-600 grit {roughly 320 grit})
Brunswick personnel have also posted here their interpretations of the actual grits of the Trizact pads since they worked closely with 3M, the actual inventors & manufacturers of Trizact. However, I checked into the 3M details on their websites and I emailed 3M directly for some more bits of information. Here is the assembled these bits of info:
An email reply to a question to 3M regarding Trizact, micron and Scotch-Brite:
To extrapolate the micron to grit conversion from 3M:
35 micron ~ 360 grit,
10 micron ~ 1100 grit
5 micron ~ 1600 grit.
-----------------------------------------------
Trizact and micron(u) grading are two separate things. Trizact products
are graded on their own scale ranging from A6 - A160.
3M Superabrasives are micron graded, that is, measuring the average size
of an individual particle on that product.
Standard abrasive grading is based on the screen mesh used to separate
out the particles for a particle grade. In simplest terms, in a 1"
line of grade 24 product there are ~24 particles. In a 1" line of
grade 600 product there are ~600 particles.
In comparison, 9u=1200 grit, 15u=600, 20u=500, 30u=400, 40u=320
The European grading system (designated by the letter P (example: P600).
This is similar to the standard grading system until you
get into grades finer than 220, then it becomes staggered the finer you
go.
Scotchbrite goes as follows:
7445 is a light duty cleaning pad
7448 is a ultra fine pad, ~1000 grit(S)
7447 is a very fine pad, ~320 grit (A)
7446 is a medium pad, ~150 grit (S)
A= Alum Oxide
S= Silicon Carbide

Another email reply from 3M.\:
If we extrapolate the European standard
for abrasives as provided by 3M, the following are the results:
A5 = P3000 = approx, 1500 grit = 3 micron
A10 = P1500 = approx. 750 grit = 12 micron
A35 = P600 = approx. 380 grit = 26 micron
------------------------------------------------------------------------
Trizact is a 3M invented product and is not micron graded. 3M developed
Trizact products in and graded them between A5-A160.
A5 = P3000, A10 = P1500, A35 = P600
Cerium Oxide has no grade, it is used for polishing. It is finer than
P3000, maybe in the 5000-8000 range.
