Belt recommendation
Considerations for belt choice:
• Abrasive anti-tack solution (wear)
• Hot rubber slab, 110-140°C (230-284°F)
• Small contact surface for optimal
backside coverage
• Open surface required for drainage
• Strong belt to handle ball-ups
• Belt speeds: 10-40 m/min (32-130 ft/min)
• Typical belt width: 1000-1400 mm (40-56 inch)

Belt recommendation
Belt and sprocket recommendations:
• S1700 FG NT Nylon with Nylon rods (dual rod system)
• S1700 FG Nylon with Nylon rods (dual rod system)
• S1700 Ultra Abrasion Resistant (Split) Sprockets - 16T, 14T or 12T
• Other options available…
S1700 FG NT

Belt recommendation
Advantages S1700 FG NT:
• Increased belt and sprocket life
• Improved backside coverage
• Decreased liquid carry-over
• Better clean-ability
• Reduced and easier maintenance
37% open area and nub pattern:
easier flow of liquid through the belt
8% contact area between rubber slab
and belt: More contact of liquid with rubber

Gravity Take-up
Min. Ø 6 inch / Ø 150 mm
Stroke: Min. 2 %,
ideally 4% of total belt lengthReturnway rollers
Min. Ø 6 inch / Ø150 mm
Belt edge guides
(both sides)
Carryway support:
Stainless Steel wearstrips

Sufficient space for
ball-ups to pass
Dunk roller with
position limiter
Ensure sufficient back-tension
(avoid sprocket disengagement)
and storage capacity for belt
elongation (minimal maintenance)
Hugger strips designed
such that it can deal
with possible ball-ups

We suggest looking at the cost of using anti-tack in terms of total cost of use.
What it costs to USE, not what it costs to BUY.
1. Rubber producers typically consume 20-50% more anti-tack than the
optimal amount needed
2. Actual product purchase cost of anti-tack is a small percentage per ton of
rubber (<$4 per ton of rubber)
3. The improper use of anti-tack causes extrusion, calendaring and molding
problems that are often unjustly blamed on the downstream processes
4. Rubber producers modify their processes to adapt to their anti-tack instead
of finding the best anti-tack for the compound and optimizing the equipment
Total Cost of Use of Anti-Tack

• Depletion or Take-Up Rate: Amount of anti-tack solution
used per ton of rubber
• All anti-tacks deplete at different rates
• Field Study
– Competitor’s powder anti-tack and SASCO PolyCoat RLS-40 diluted to 4% solids (500 gallons)
– 500 gallons of PolyCoat RLS-40 covered twice as much rubber as the competitors dip
