Sometimes in products, or in industrial applications, vibration is an issue that requires a solution. In our business, we create solutions called vibration damping, and we do it with extruded rubber components.
In fact, when vibration is an issue, the right rubber formulation can make all the difference. But first, let&#;s get back to basics. What is vibration?
Vibration is a mechanical occurrence where shaking or oscillations occur due to imbalances in a rotating part (like a motor) or uneven friction. If vibration isn&#;t controlled, it can cause damage to the entire assembly or unit, specific parts, or even worse, fail and cause damage far beyond a part failure. To prevent any of these bad things from happening, you need vibration damping materials and components.
Vibration damping uses materials, often rubber, to absorb vibrations caused by machinery or moving parts. It
can take the form of rubber vibration mounts, pads, washers, isolators, or gaskets, and can be made with a variety of rubber compounds, but are commonly made of natural rubber, EPDM, neoprene, and butyl rubber.
We&#;ll cover these materials one by one, but first, a few qualities that vibration dampeners require: adhesion to substrates, durometer, and resistance to other substances (ie, chemicals, oils, heat). Which material you choose for your vibration damping needs will depend on your application, and it&#;s important to know how different rubber compounds perform under different conditions.
No material can deaden vibrations if it doesn&#;t adhere to your parts or components. If a rubber doesn&#;t adhere well to your substrates, it will fall off and render the damping useless.
Making sure the rubber used in your damping components isn&#;t too hard or too soft is crucial. Too hard and you may lose damping ability; too soft and your part may tear and fall off. It&#;s important to test different formulations to determine the exact right durometer for your project.
Considering the environment in which your rubber components will be used is extremely important. Vibration dampeners need to survive and lead a productive life, so understanding what elements the rubber will be exposed to is crucial. Temperature, oils, chemicals, weather, etc., can wear down parts and cause failure so it&#;s vital to understand rubbers&#; interactions with its environment.
There are a few different vibration damping rubber materials used in most applications:
Natural rubber is a good vibration damping material that features high tensile strength, but its main drawback is that it doesn&#;t hold up well outdoors or in conditions that feature oils, due to its poor oil resistance.
EPDM is a synthetic rubber that features high resistance to heat and weather and features excelled substrate adhesion and durometer. It can also be formulated in numerous different compounds for many different applications.
Neoprene excels in two specific areas for vibration damping: its superior adhesion to substrates, and its resistance to oil. Neoprene is a bit more expensive than other rubbers but its ability to stick to substrates (especially metal) and its ability to perform in oily conditions makes it a great damping option.
Butyl rubber is a synthetic rubber that features low gas and moisture permeability and is extremely resistant to heat, abrasion, and tearing, which makes it an excellent option for damping vibrations.
As you can see, vibration damping parts and components can be made with a variety of rubbers, but it is crucial to find the best performing and most cost-effective option for your project. But that can be difficult unless you are a rubber expert.

Vibrations are never invited in the world of machines. Be it cars, motors, machine tools, buildings and constructions or oil and gas platforms, vibrations create huge troubles for these industries.
And this is where the vibration absorber sets its foot in. Utilizing the rubber components design & manufactured by Sujan Industries, one of the pioneers among the top rubber companies in India, the vibration absorbers help to reduce the unwanted vibrations and ensure smooth running of the entire process.
Now let&#;s start the basics before we dive deep into the reasons for rubber being used in vibration absorption.
Vibration, in dynamic machines, occurs when there&#;s an imbalance of moving mass. It causes an undesirable vibration and stress that minimizes the durability of the machine.
Now, to get rid of the vibration, a tuned spring and secondary mass as a system are attached to the revolving apparatus. This technique is called vibration absorption and the mass-spring system is called vibration absorber.
Rubbers are compounded with such various additives that make it so versatile and useful for almost limitless numbers of industrial applications. Specifically, natural rubbers are valuable as spring materials for their longevity, flexibility, lower price and durability in high temperatures.
Besides, Rubber has enough high shear modulus compared to other materials. That means, when a rubber material is a stressed parallel to its cross-sectional area, it can be stressed more before it becomes completely deformed. Whenever rubber materials receive any vibrational stresses, rubber vibration absorbers absorb them before damage or transferring the vibrations. All these aspects make rubber a great component for vibration absorption, indeed. Hence, Rubber is the best material used as a vibration absorber.
Among various types of vibration absorbers, one that is used daily and widely is passive vibration absorber. This consists of a spring and damper. Whereas the spring softens the vibrations and pushes, the damper ends the oscillation. Mainly the spring acts as the absorber here and the damper helps the spring to do the task.
There are a handful of instances of the passive vibration absorbers that are used daily. One such instance found is the suspension bracket of an automobile. One can easily understand the operations of passive vibration absorbers and isolators by the way it works in automobile suspensions. The rubber parts found in every suspension bracket soften the push and impact of the road on which the automobile travels. Another element of the suspension found in an automobile is the shock-absorber.
Most of the time when we think of spring, an image of a spiral metal comes to our mind. But the spring used in Passive Vibration Absorbers has to be of rubber for different reasons.
With steel springs, there&#;s a linear relationship between the force and the bounce. But rubber springs can be designed to give varied stiffness in non-linear directions. Rubber materials are much more stretchable than steels before they get completely damaged.
Rubber products are easier and more convenient to handle and install than steel springs. Also rubbers have more capacity to store energy and when deflected it has the potential to convert some energy to heat. This is the reason why heat doesn&#;t spread in rubber much unlike steel.
Natural rubber without fillers can provide damping in a system subjected to vibrational forces. Thus unlike steel, the inherent damping ability in rubber makes it more potential as a vibration absorber.
