Cellular Plastic Bumpers

Bumpers are provided in compliance to either CMAA no. 70, or AIST standards. The optimal choice depends on the impact speeds, impact masses, required impact forces, deceleration, and space restrictions. Bumpers compressed up to 70% of the bumper length, result in little lateral expansion, stresses and so minimize material fatigue. Large deflections provide lower deceleration rates and protect equipment high impact forces. Cellular plastic bumpers have increasing force with increasing compression. This will result in fewer oscillations than constant force-compression bumpers when used in undamped applications. Resistant against ozone, oil, grease. Polyurethane is not stable with acids and bases. Operating temperatures –40 deg C to +80 deg C

Rubber Bumpers

Bumpers are provided in compliance to either CMAA no. 70, or AIST standards. The optimal choice depends on the impact speeds, impact masses, required impact forces, deceleration, and space. Excellent wear resistance. Special rubber 75 deg shore A. The mechanical characteristics like elastic strength, compression recovery, tear resistance are determined by rubber additives. Bumpers can compress up to 50% of the bumper length. The lateral deflection can be up to 1.4x the original diameter. Rubber is less suseptible to hydrolysis than foamed polyurethane.
