Mining is one of the most severe industrial environments for technical materials. Equipment and components are constantly subjected to intense abrasion, impact, heavy loads, and aggressive operating conditions. In this scenario, choosing the right material directly influences component durability, process efficiency, and maintenance costs.
It is precisely in this context that polyurethane elastomers (PU) have been gaining ground in the mining sector, offering a combination of properties that make them superior to many traditional materials.
With the launch of Amino’s AMITHANE elastomer line, we developed systems designed to deliver high wear resistance, mechanical stability, and durability in high-demand industrial applications.
Why use PU elastomers in mining?
Compared to materials such as rubber, metals, or other conventional polymers, polyurethane elastomers offer important advantages for applications subjected to impact and abrasion.
Among the main differentiators are:
- High abrasion resistance
- Excellent tear resistance
- High impact absorption capacity
- Good dimensional stability
- Longer service life in aggressive environments
- Reduced maintenance and operational downtime
This combination allows PU-made components to maintain mechanical performance even under severe working conditions.
Applications of PU elastomers in the mining sector
Amino’s Amithane elastomer line was developed to serve different components used in mining operations, especially in ore transport, impact, and classification systems.
Among the most common applications are:
Ore transport systems
- Self-aligning idlers
- Conveyor belt rollers
- Belt limiters
- Side guides
Impact and wear components
- Impact beds
- Primary, secondary, and tertiary scrapers
- Pipe linings
- Internal hydrocyclone linings
Classification and crushing equipment
- Vibrating screen panels
- Stone-breaking components
- Separation and classification accessories
In these applications, polyurethane acts by absorbing impact, resisting abrasive wear, and protecting structural equipment with a longer service life than other conventional materials.convencionais.
AMITHANE Line: three families of elastomers for industrial applications
To meet the different demands of the mining sector, Amino developed three main families within the AMITHANE line, each with specific performance characteristics.
AMITHANE ATP – PPG-based
PPG-based systems offer excellent performance in applications requiring hydrolysis resistance and stability in humid environments.
Among their main characteristics are:
- Good abrasion resistance
- Excellent hydrolysis resistance
- Mechanical stability
- Good performance in environments with water or moisture presence
Because of these characteristics, they are recommended for industrial applications exposed to humid conditions or environments with constant water presence.
AMITHANE ATT – PTMEG-based
PTMEG-based systems also provide excellent hydrolysis resistance, as well as high fatigue resistance and superior mechanical performance in dynamic applications.
Among the main differentiators are:
- Excellent hydrolysis resistance
- High mechanical resistance
- Excellent behavior in continuous-motion applications
- Good wear resistance
These systems are widely used in components subjected to cyclic loads and constant wear.
AMITHANE ATS – Polyester-based (Ester)
Polyester-based (Ester) elastomers provide excellent tear resistance, making them ideal for applications where the structural integrity of the material is essential.
Among the main differentiators are:
- High tear resistance
- Good mechanical resistance
- Excellent structural behavior in impact and abrasion applications
This characteristic makes ester systems especially suitable for components subjected to intense mechanical loads.
Hardness range for industrial applications
Elastomers in the AMITHANE line can be formulated at different hardness levels to meet the specific needs of each application.
The working range includes materials from:
70 Shore A to 73 Shore D
This variation makes it possible to adjust elastomer behavior according to the need for impact absorption, wear resistance, or structural stability.
Materials engineering applied to mining
The performance of an elastomer depends not only on its chemical formulation, but also on properly matching the material to the application.
At Amino, formulation development takes into account factors such as:
- type of abrasion
- impact intensity
- presence of moisture or water
- mechanical loads
- equipment operating conditions
This work makes it possible to supply materials tailored for severe industrial applications, ensuring reliability and performance in the field.
Polyurethane elastomers represent a highly efficient solution for mining applications. Their combination of abrasion resistance, impact absorption, and durability helps increase component service life and reduce operating costs.
With the AMITHANE ATP, ATT, and ATS line, Amino expands its portfolio with elastomers designed to meet different demands in the mining sector, offering technical performance, process stability, and reliability in critical applications.
