Belt applications

The coagulated material consists of about 50% polyisoprene and the remainder is primarily composed of resins. Deresinated balata has been used as an alternative to gutta pereha, which it resembles in properties and also in belting applications. It is still used for making high-quality golf ball covers but for the cheaper balls it has now been replaced almost entirely by the ionomers (see Chapter 11). 

From Equations 3-24 and 3-25, an optimum velocity may be found for higher speed V-belt applications. This optimum velocity (ft/s) is...

Acsium is said to have been designed for use in synchronous drive belt applications. 

For most filtration applications involving monofilaments, the majority of diameters used are in the range 0.15-0.35 mm, yielding fabric area densities between 180 and 450 gm. Heavy duty filter belt applications, on the other hand, usually employ diameters from 0.3 to 1.0 mm resulting in area densities from 500 to... 

So-called link structures (Hardman, 2000c) have also found favour in some heavy-duty filter belt applications, largely due to their durability, particularly where coarse abrasive slurries are being processed. Unlike traditionally woven filter belts, there is also no requirement for a mechanical seam with link structures, which is frequently the first point of failure in a conventional filter belt. 

Hoff reported on the use of certain melamine resins that were able to function as standalone or one-component systems when used in steel wire belt applications [39]. One-component melamine resins were described that were capable of forming a network in the rubber without the need for a co-reactant such as resorcinol. The performance of these new resins was compared to that of some classic two-component methylene donor-methylene acceptor systems. The new, one-component systems gave good initial and aged adhesion, equivalent tensile and dynamic mechanical properties and superior crack growth resistance than the currently used two component systems. 

HNBR is also used extensively in other belt applications as well, and in hose and seals. Some examples of these seal applications include in-tank seals, power steer-... 

DBEEA is commonly used in hose and belt applications as well as printing rolls, seals, and tubing.

Since NBR/PVC has basic good flame resistance it may be used in hose and belt applications where this is a requirement. A 70/30 or 50/50 NBR/PVC base elastomer should be selected and use non-black fillers, including alumina trihydrate (e.g.. Hydrated Alumina 983), magnesium hydroxide, and zinc borate (e.g., Firebrake ZB) as flame retardant fillers. Calcium carbonate will assist in reducing smoke emission. In addition a phosphate plasticizer such as Kronitex 100 or chlorinated paraffin like Chlorowax 40 should be used as the only plasticizer types. 

ACSM elastomers were developed primarily for timing and multi V-belt applications as well as other dynamic or low-temperature applications [10]. These polymers exhibit improved low-temperature resistance, lower hysteresis, and mechanical properties (due to their linear back bone) compared with CSM (Figure 9.12).

Hose and belt applications have traditionally been cured with sulphur-accelerator cure systems. In recent years.
