Volume Discount

[NonBuren is a vibration-proofing material used in the "Rail Star" and "Nozomi" series of bullet trains in Japan]
NonBuren is a completely new form of ultra-soft elastomer made using a newly developed base material of a polyurethane-like gel elastomer.
Used in a broad range of applications, from underfloor vibration- and sound-proofing on 700 Series Nozomi bullet trains to damping on precision machinery such as semi-conductor manufacturing devices and image-based measuring devices.

[NonBuren Characteristics]
· 2 to 4 times more effective at vibration proofing than conventional vibration-proofing rubber.
· Outstanding oil resistance. Can be used semi-permanently
· Significantly higher shock-absorbing properties than natural rubbers, silicone, etc.
· Outstanding strength against bending and tearing
· Helps keep equipment size down

[Round NonBuren]
Made of urethane, giving it excellent vibration- and shock-absorbing properties. An insulator type that easily mounts to the 4 corners of large, heavy-load objects.
