Pepson Products are manufacturers of polyurethane, PU, hydro cyclones in a wide range of sizes and forms for a diverse number of applications. Wherever there is a requirement in an industry to separate out heavier elements from pressurized liquid mix polyurethane hydro cyclones can often be found. Applications include:
· In pulp and paper mills to remove sand, staples, plastic particles and other contaminants.
· In the drilling industry to separate sand from the expensive clay that is used for lubrication during the drilling.
· In industry to separate oil from water.
· In metal working to separate metal particles from cooling liquid.
· In potato processing plants to recover starch from waste water.
· In mineral processing hydro cyclones are used extensively both to classify particles for recirculation in grinding circuits and to differentiate between the mineral gangue
Pepson manufacture hydro-cyclones using the Pepson 1FA range of high hardness, high load bearing polyurethane, PU. Pepson 1FA grades are used where high hardness is required as the range goes from 80 Shore A up to 60 Shore D with 75 Shore D available as a special request. Pepson 1FA is used to make hydro cyclones where hydrolysis and heat resistance is required as well as abrasion resistance.
| 1 |
It is the most versatile, toughest, abrasion resistance elastomer available. It is as soft as Shore A durometer 10 and hard as Shore D scale durometer 85. |
| 2 |
It could be cast into practically any shape, size or complex geometry desired wheels,
gears, O rings, gaskets, tires, roller blades, skate boards etc. |
| 3 |
It can be formulated with high resistance to stresses and it tends to maintain shape and mechanical properties aster fatigue stressing. |
| 4 |
Casting Polyurethane maybe pigmented to resist degradation by elevated atmospheric oxygen and ozone atmospheric concentrations. |
| 5 |
Many cast polyurethane elastomers compounds remain flexible at extreme low temperatures and possess outstanding resistance to thermal shock. Low temperature resistance of polyurethanes make cast parts very practical in extreme arctic conditions. |
| 6 |
Casting polyurethane parts can be made flame resistance by incorporating flame retardants into their formulas. |
| 7 |
Polyurethane can be cast with coefficients of friction varying from very low, for items like bushings, bearings or wear strips, or very high, for items like tries or rollers. |
