Rubber metalmounts
Natural-based rubber compounds (NR) are generally and preferably used for the production of anti-vibration mounts. On specific request, synthetic-based compounds can also be used, such as nitrile-based compounds (NBR), EPDM, silicone, neoprene/chloroprene (CR), polyurethane (PUR), or fluorinated elastomers (FKM), with hardnesses varying from 30 to 90 shore.
Many customers also come to us for the supply of anti-vibration mounts with or without metal coupling, made with special compounds and specific hardnesses, to guarantee oil resistance, abrasive or self-extinguishing properties that are necessary in various fields of application.
For these requirements, we prefer to have a preliminary meeting with customers to design an ad hoc product based on their needs, in natural rubber or in compounds with specific elastomers such as EPDM, NBR, HBR, SBR, PUR.

We guarantee flexibility and customisation
With decades of experience, we are specialised in the production of standard or customised anti-vibration mounts in natural-based rubber, ensuring high quality standards and flexible services, which allow us to meet and satisfy your needs in a short time frame.
Our engineers are able to develop new anti-vibration components or customise already existing ones on the catalogue, offering solutions such as gaskets, springs and supports with metal mounts that can be used in the industrial sector. The core of our mission always remains the focus on Customer satisfaction and om the highest possible quality standards.
The most suitable compound for your application
At least three important parameters must be taken into consideration when deciding on the type of compound to use to make the most suitable anti-vibration component for a specific application:
- Temperature-what temperature or temperature range the anti-vibration component will be subject to during operations (operating temperature and any peaks)
- Contact with agents-oil, grease in general, fuels, acids and solvents can have a significant impact on the anti-vibration component if they come into contact with it
- Abrasion-above all in dynamic applications, it is important to take the abrasion resistance parameter into account when making the choice
When the most suitable compound for the specific application has been defined, other important properties of the rubber to take into consideration are hardness, mechanical strength, and elongation.
All the information provided is generic and should be considered as being subject to case-by-case assessment.
Natural-based rubber
Excellent physical and mechanical properties. Excellent elastic performance, abrasion and wear, shear and tear strength and ultimate elongation. Working temperature-20°C +80°C (peak). Poor resistance to oils, greases, acids.
CR - Chloroprene Neoprene
Good resistance to weathering, ageing and chemicals.
EPDM
Good resistance to heat and ageing, weathering, abrasion and non-mineral oils. Good elasticity and mechanical properties.
NBR-Nitrile Butadiene Rubber
Depending on the percentage of nitrile in the compound, it offers fair to excellent resistance to mineral oils and greases and petroleum hydrocarbons. Good resistance to water, tear and abrasion, good flexibility and mechanical strength.
Poor resistance to ozone, weathering, direct sunlight.
Silicone
Excellent temperature resistance (- 50°C up to 200°C-HT silicone even higher), excellent resistance to ageing, ozone and weathering. Good resistance to mineral oils and greases.
FKM
Fluoroelastomer rubber, better known as Viton® (Du Pont brand)
Excellent resistance to high temperatures (up to 200°C), chemicals, lubricants, heat and flames. Excellent resistance to ageing, ozone and weathering.
Limitations: besides the cost, lower abrasion resistance compared to the NBR compound.
PUR and polyester rubbers
Exceptional tensile strength, abrasion and tear resistance. Excellent mechanical properties (tensile strength and elongation).
It degrades quickly as the temperature rises.
