QFeatures of Low Rebound Urethane, Low Elasticity Rubber (Hanenaito®)· Low Rebound UrethaneIt has the same properties as, urethane, and excels in shock absorption. With more resistance to compression than normal urethane, it is hard to deform. Not suitable for absorption of large impact energy because its tensile strength and elongation resistance are weaker than that of urethane of the same hardness.
· Low Elasticity Rubber (Hanenaito®) EHanenaito® is a registered trademark of Naigai Rubber Industry Co., Ltd.It is used as cushioning material pallet damper, conveyor machine, precision instrument etc, because of its good elongation and shock absorption. Also it is used as vibration absorption materials of various precision instruments because of its excellent vibration absorption characteristics.

QUrethane (Ether Type, Ester Type) Property Comparison QDiscoloration of UrethaneUrethane may experience discoloration and yellowing with age.Urethane turns yellow by aging, but physical property or characteristics remain unchanged.Discoloration is distinct especially with antistatic urethane and Vulkollan®. See the explanation below.
Vulkollan® has poorer color stability against ultraviolet rays than general urethanes due to its unique composition.Pictures below show the process of change in colors of a sample exposed to outdoor sunlight.
* No change in physical property or characteristics due to discoloration.

QFeatures of UrethaneMaterial Feature
General UrethaneEther, Ester Polyurethane
Excels in strength in repeat use and shock-absorbing properties. Can be used for applications such as Mechanical Stoppers.Ester Type is Hydrolytic. Do not use in humid and wet areas.
Antistatic Urethane Excels in antistatic effect.Can be used where mechanical strength and anti-static measures are required.
Heat Resistant Urethane
This urethane has greater heat resistance up to 120°C. (70°C for the general urethane) Suitable for use in applications where high material strength in high-temperature range is required.
Super Abrasion Resistant Urethane(Vulkollan®)
Vulkollan® is a super abrasion resistant urethane which is far superior to conventional urethanes in abrasion resistance and load bearing. Excels in tearing strength. 6 times higher in abrasion resistance and 1.5 times in material strength than the general urethane.
Abrasion Resistant Urethane
Unique composition realized abrasion resistance 2.5 times higher than general urethane at low cost. Helps to reduce the exchange frequency. Color is dark brown.
Ceramic UrethaneThese MISUMI original urethane sheets are unique mixture of ceramic particles, excelling in abrasion resistance and have smooth machined surface in spite of its low hardness. Note that cutting due to contact may cause dust.
QFeatures of Shock Absorbing Foam P.415Excellent sound dampening and vibration absorbing characteristics.Flexible material can be pasted on curved surfaces with ease.Lightweight material can be applied on large panel areas.Best suited for human body protection. Can be pasted in multi-layers where more protection is needed.
QFeatures of Special Urethane Foam SOFRAS® P.426This special urethane foam excels in water retention and abrasion resistance allowing it to be used in industrial purposes such as application and moisture absorption. SOFRAS® excels in abrasion resistance and requires less concerns about dust shedding, whereas the use of sponges and felts may result in shedding of dust and felt fiber.

A major characteristic is the three-dimensional slow recovery, the function to recover after compression slowly and in multiple directions.Pressed as thin as shown in the photo and recovers to the original shape gradually after being released from pressure.* The double-layer structure of the gel part reduces stickiness.
Steel Ball Collision Noise Level Test
* A steel ball (20Ø, 36g) is dropped on a wooden base from a 55cm height, and the sound pressure level is measured with a microphone at a distance of 50m, positioned 50cm above the ground.
