Desmopan®

Flexible high tech material

in mining applications


Desmopan® – Thermoplastic Polyurethane

1. Outstanding resistance to abrasion and strokes

2. Great resistance to penetration of sharp objects

3. Resistance to oil and grease

4. Elasticity in large temperature window ( -70°C ... +120°C)

5. Does not irritate skin

6. No plasticizers – no ageing (huge advantage over rubber ageing)

7. Perfect welding – welding strength = material strength


Main Properties



Applications for mining industry

Desmopan® in mining industry

Wear linings Screens Belts Hoses



Wear linings

Desmopan® Performance

Desmopan® 4mm – Replacement after 2

months.

Rubber 20mm – Replacement after 2

weeks.

Conclusion:

5 x less thick ; 4 x longer life time

= 20 x longer life time, considering the

same thickness.



Wear linings

Desmopan® Performance

Vs. Rubber – Up to 20 x longer life time

Vs. Mn-steel – Up to 20x longer life time

Vs. Hardox (if particle size < 40mm) – Up

to 10x longer life time

It can not be given a general statement, how much longer Desmopan ® linings

work – each case must be tested separately


1. Chutes

2. Mill linings

3. Launders

4. Magnetic separators

5. Silos

6. Underpan

7. Rotating separators

8. Air cyclones

9. Slurry channels

10. Cones


Wear linings

11. Vibrating feeders

12. Buffer at conveyor belt end

12. Belt scrapers

13. Wagons

14. Dump trucks



Screens

Up to 3x longer life time

then metal screen

Up to 20x longer life

time then metal screen

Up to 20x longer life

time then metal screen

In the test performed, with the screen

size 30 x 30, after the processing

70.000ton of minerals, the abrasion loss

was less than 1.5mm and without

corrosion.



Screens

It can not be given a general

statement, how much longer

Desmopan® screens work – each

case must be tested separately



Conveyor belts

Vulcanizing 2mm of Demopan® in

rubber belt increases your life time

up to 4X

Side curtains are not destroying

conveyor belt additionally.

Sediment is not destroying the belt,

through penetrating (since no aging

as rubber)

It can not be given a general

statement, how much longer

Desmopan ® linings work – each

case must be tested separately



Hoses

Advantages of using the TPU:

- Abrasion resistance

- Flexibility at low temperatures

- No Plasticizers

- Hydrolysis resistance

Depends on final requirements, a

variety of grades is available.

Baytec® SPR

Spray System


Baytec® SPR

• 2-components spray

• 100% solids

• Thixotropic

• Fast curing

• Curing in room temperature

• Different substrates

• Complex shapes substrates


Main properties

• Abrasion resistance

• Chemical resistance

• Sound insulation

• Resistance to hidrolysis

• Water resistance

• Tear propagation resistance

• Weather resistance

• Sealing cracks

• Gas permeability

• Adhesion

• Thermal resistance

Baytec® SPR


Protection for abrasive wear and

corrosion of several substracts.

Hardness suitable to usage.

Working life extended even for

drastic conditions of usage due

to the high adhesion to the

substrate and the resistance to

wearing.

Baytec® SPR


Protection of complex structures

fo different substracts exposed

to extremely temperature

gradient and chemical products

as secondary containment.

Cycle of expansion and

contraction require a material

that maint the high tensile na

elongation over time and under

UV exposure and chemical

degradation.
