The following products are recommended and typically used to care
for any brand of Rubber Compressive Shrinking Belt:
NO-TALC GRINDING CLOTH (S-88
This product was developed several years ago in an attempt to alleviate
the time needed to "clean up" after grinding a rubber belt. As
anyone who has ground a belt knows, when Talc is introduced to the belt
face it quickly becomes airborne as the grinding roll touches it. This airborne
Talc then travels and settles everywhere. The end result is a mess that
takes as long or longer to clean up than it does to grind. Yes, the rubber
dust is also suspended in the air, but no where near the extent of the Talc,
principally because it is heavier and tends to collect at the base of the
The NO-TALC CLOTH consists of a patented abrasive and bond structure
that prevents "loading" of the abrasive and reduces friction
build-up so the abrasive grinds cooler. The special cloth backing has been
pre-stretched and stabilized to create tremendous dimensional stability
of the product. This stability means less down time for "re-tightening"
of the abrasive on the grinding roll -- formerly a common complaint.
Popular roll sizes and grits, listed below, are inventoried in our Charlotte,

*NOTE: OUR NO-TALC abrasive is guaranteed
to be "endless" without having any "seams" or "splices".
This is an extremely important virtue as, otherwise, a depression will
be ground into the rubber belt surface causing "fabric mark-off"

Several grades are available, but we usually stock TMT
YELLOW and TMT PURPLE. Both are available in 5 lb. boxes and
55 gallon drums.
Differences between the two?
TMT PURPLE is the coarsest grain size Borax makes, then TMT YELLOW,
followed by TMT RED. To a degree, the coarser the grain size the
more "abrasive" the soap and hence, the more cleaning action.
After years of providing all three, TMT PURPLE has been the one most
Why BORAX SOAP?
Generally, a highly alkaline synthetic, non-sudsing, detergent having a
pH of about 10-11 is satisfactory. Actually, any such synthetic detergents
("All", "Borax" or "Ivory") will work equally
We suggest BORAX primarily because it is so readily available, we are able
to offer better pricing, packing is more conducive to a mill environment,
and because it is available in several different grades (see above).
What's the need for Soap at all?
We recommend the use of soap for cleaning Rubber Belts of all brands. The
cleaning process is important as it serves to remove any "sizing"
build up that has developed on the belt's surface. This prolongs the grinding
frequency which, in turn, lengthens the belt's life and prevents unnecessary
In addition, Soap is used to relieve the "surface tension" on
the belt's surface after grinding. Otherwise, the cooling water may not
adhere as well to the face of the belt.
We invite you to request samples. To do so, please see FAQ
Like the Soap discussed above, Talcum
Powder is also available in any number of different grades. Too fine a grade
causes coagulation of the Talc while grinding; too coarse a grade prevents
obtaining the desired finish on the belt's surface during the end of the
grinding procedure. For these reasons, we experimented with numerous
grades before settling on the one we have sold for years.
Again, we welcome the opportunity to provide you a sample. To request your
free sample simply visit the FAQ Section.
The word "wax" is actually a misnomer as technically this
product is not a wax. Instead, it is a chemically formulated
compound, with wax-like properties, designed specifically by us for use
as a lubricant on any Rubber Belt. It contains no petroleum-based
ingredients, vegetable or bee's wax, which other "knock-off" products
contain, and which are detrimental to natural rubber.
Be careful what you buy, as all products slated for this use are not the

Durometers are available in a myriad of types for measuring the hardness
of just about everything. For our purposes, however, we are focused on durometers
for measuring the hardness of natural rubber and specifically Rubber Belts
used for Compressive Shrinking.
We offer three types of Type A Durometers: Shore Pencil, Shore
Round(center) and Kori Quadrant (right).
|| Shore is the originator of the Durometer Hardness Tester.
Their durometers are built to last a lifetime and can be returned to the
factory for calibration and repairs as needed. The Round style durometer
is supplied with a test block for checking the accuracy of the gauge and
a vinyl covered steel case for protection. The Pencil style is supplied
boxed with a sheath and a cleaning brush.
Kori durometers are manufactured as a more economical alternative
to Shore. Still an accurate and effective tool, but without the
capability of being calibrated and/or repaired. It is supplied with
a UHMW protective case.
|Our thoughts on the three types:
Buy the Shore Round style if you can afford the US$400.00 premium.
Positives: Easy to read; repairable; can be calibrated. Downside:
Does not hold the reading once removed from the source.
||Kori is an excellent alternative for an excellent price. Downside:
Not repairable; does not hold a reading once removed from the source.
||ShorePencil is easy to carry due to its small size. Positives:
Holds reading when removed from source; good price point. Downside: Difficult
||Please contact us for current pricing and availability.
An easy and highly effective means of repairing damaged areas anywhere on
a Rubber Belt. This material is available in sheet form approximately 2mm
thick x 230mm wide x 280mm long (or longer if requested). It is easy to airmail
as it is lightweight and non-flammable. When the product is cured, the durometer
is approximately 40° A.Picture
