Description/Basics

Foam plates and rubber plates are provided for damping or for sound proofing. MISUMI offers these in various Shore hardening for a wide variety of tasks. Due to the variety of materials, different resistances to environmental influences are possible depending on the application. The foam plates reduce sound in machines and can reduce the sound emissions of a system. For more information on foam characteristics, follow this link.
Rubber plates or foam plates are also suitable in conveyor systems to absorb components to be transported at a dampened level or to protect them from damage as a lateral guide when the components bump into each other. Hard rubber panels or low-impact rubber or foam panels reduce the impact energy of the components. These minimize and lower the vibrations in an application.
In addition, MISUMI offers highly abrasion-resistant polyurethane (Vulkollan), which has an abrasion resistance that is six times higher than with conventional polyurethane.
Ceramic polyurethane plates contain ceramic particles. After machining, these can have a smooth surface despite low Shore hardness.
The polyurethane rubber plates are also available antistatically. The specific resistance of antistatic polyurethane plates prevents static charging. This prevents any damage to electronic components.
For applications with higher temperatures, MISUMI offers heat-resistant polyurethane rubber, which can withstand a temperature range of up to approx. ~120°C (see the product specifications for exact information).
MISUMI also offers low-friction and anti-friction rubber plates. Low-friction rubber plates are often used in the gentle component guide for belt conveyors and roller conveyors.
Felt plates have the property of absorbing or dispensing oil and other liquids via the capillary effect. This property can be used to remove, for example, excess oil on a belt conveyor.

In addition, MISUMI offers rubber plates and foam plates that are self-adhesive for simplified assembly. Furthermore, you will find double-adhesive tape for attaching rubber plates and foam plates.

Additional properties on foam panels and rubber plates can be found in the Properties PDF.

MISUMI also offers these products in a round shape as discs and sleeves made of rubber, natural rubber, foam and felt.

Frequently Asked Questions (FAQ)

Question:
How can you attach a rubber plate?: Answer:
A rubber plate can be attached with double-adhesive tape. MISUMI offers rubber plates with configurable through holes or counterbores with adhesive tape.
Question:
Do you have screw-on rubber panels?: Answer:
MISUMI offers rubber plates that can be screwed on via a through hole or counterbore. The rubber plates with counterbores are well suited for applications that need to form a flat surface.
Question:
Is NBR oil-resistant?: Answer:
The NBR rubber is oil-resistant and is often used as a sealing material for rubber or foam. In addition, NBR has good thermal resistance, which in combination with high abrasion resistance is the best suited NBR material for seals.
Question:
Which material reduces vibrations well?: Answer:
Silicone gel vibration dampers reduce vibrations well. This elastic material reduces the transmission of vibrations to the subsequent component and also contributes to the acoustics.
Question:
What is Vulkollan?: Answer:
Vulkollan is a highly abrasion-resistant polyurethane rubber that has high wear resistance. It is one of the high-performance rubbers that has little pressure deformation and can withstand high impact forces. In addition, Vulkollan has a high tear strength. However, over time Vulkollan may change its colour, but without losing its mechanical properties.
