DUNLOP ROS COLDSTAR

Dunlop ROS Coldstar rubber compound is designed to resist the highly damaging effects of both mineral and vegetable oils (under ASTM ‘D’ test conditions) while still being able to remain fully functional in extremely cold conditions where temperatures can be as low as minus 40°C. In addition to these exceptional qualities, Dunlop Coldstar ROS also provides extended wear life because under EN/ISO 4649 / DIN 53516 test conditions it exceeds the abrasion requirements in DIN ‘X’ and ISO ‘H’ standards by more than 20%. As with all Dunlop cover grades, Dunlop ROS Coldstar is fully resistant to the effects of ground-level ozone and ultraviolet light (EN/ISO 1431).

The many positive advantages of Dunlop ROS Coldstar include:

Dunlop ROS Coldstar is highly resistant to both mineral and vegetable oils (ASTM ‘D’ 1460 testing)
Is able to remain fully functional in temperatures as low as minus 40°C
Abrasion (wear) resistant levels are more than 20% superior to DIN ‘X’ and ISO ‘H’ standard abrasion requirement
Anti-static (ISO284 / EN20284) and can therefore be used in ATEX classified areas
Ozone & UV resistant EN/ISO 1431
REACH compliant (EC 1907/2006)

DUNLOP RAS & DUNLOP RAS COLDSTAR

Dunlop RAS rubber compounds were specifically developed by Dunlop technicians to provide unbeatable wear life. Dunlop RAS (and also RAS Coldstar) has an abrasion resistance under EN/ISO 4649 / DIN 53516 test conditions that is more than 50% superior to the highest abrasion tests standards set within DIN ‘W’ and ISO ‘D’. This means that Dunlop RAS and Dunlop Coldstar RAS is ideally suited to conveying even the most aggressively abrasive materials. Both Dunlop RAS (minus 40°C) and Dunlop Coldstar RAS (minus 60°C) also have outstanding resistance to extreme cold. They are therefore able to remain fully functional in some of the toughest and most inhospitable operating conditions in the world.

The many positive advantages of Dunlop RAS and Dunlop RAS Coldstar include:

Dunlop RAS is able to operate in temperatures as low as minus 40°C
Dunlop RAS Coldstar is able to remain fully functional in temperatures as low as minus 60°C
Abrasion (wear) resistant levels more than 50% superior to DIN ‘W’ and ISO ‘D’ standard abrasion requirement
Anti-static (ISO284 / EN20284) and can therefore be used in ATEX classified areas
Ozone & UV resistant EN/ISO 1431
REACH compliant (EC 1907/2006)

DUNLOP RES

Dunlop RES rubber compound was specially developed by Dunlop technicians as a solution for applications that convey particularly aggressive materials such as heavy, sharp rocks including granite and dolerite. Dunlop RES has exceptional resistance to the impact, abrasion, cutting and gouging caused by heavy, sharp materials and high drop heights. It also possesses outstanding resistance against tear (rip) propagation. These exceptional physical properties, exceeding DIN ‘X’ and ISO ‘H’ requirements, combined with a resistance to abrasion under EN/ISO 4649 / DIN 53516 test conditions which even exceeds DIN ‘W’ and ISO ‘D’ standard requirement, means that Dunlop RES provides a truly unbeatable wear life. It is also able to operate in exceptionally cold operating conditions as low as minus 40°C.

The many positive advantages of Dunlop RES include:

Exceptional resistance to impact, abrasion, cutting and gouging, exceeds DIN ‘X’ and ISO ‘H’
Outstanding resistance against tear (rip) propagation
Abrasion (wear) resistant levels exceed DIN ‘W’ and ISO ‘D’ standard abrasion requirement
Dunlop RES is able to operate in temperatures as low as minus 40°C
Anti-static (ISO284 / EN20284) and can therefore be used in ATEX classified areas
Ozone & UV resistant EN/ISO 1431
REACH compliant (EC 1907/2006)

OIL RESISTANCE

Conveying materials that contain oil, fat, grease or chemicals can have a very detrimental effect on the performance and life expectancy of a conveyor belt because they penetrate into the rubber causing it to swell and distort.

ANTI-STATIC

In environments where coal dust, biomass, fertilizer or other combustible elements are involved it is essential that the conveyor belt cannot create static electricity that could ignite the atmosphere.

ABRASION (WEAR) RESISTANCE

Rubber that is designed to resist heat, fire or oil invariably has a lower resistance to
abrasion (wear).

FIRE RESISTANCE

Safety first! Having played an instrumental role in the creation of fire-resistant conveyor belting, we take great pride in making sure that our fire-resistant belts really are the safest conveyor belts in the world.

HEAT RESISTANCE

Of all the demands placed on conveyor belts, heat is usually the most unforgiving and damaging. High-temperature environments accelerate the ageing process, which causes the rubber to harden and crack.

OZONE & UV RESISTANCE

At ground level, ozone is a pollutant. Ozone increases the acidity of carbon black surfaces and causes reactions to take place within the molecular structure of the rubber. This results in surface cracking and a decrease in tensile strength. The same consequences apply to exposure to ultraviolet light and is referred to as ‘UV degradation’.
