Step type shock absorption material
Content:

Product name: Stepped shock-absorbing material


Polyurethane shock-absorbing material can prevent the workpiece from scratching and cracking during tightening; it has a good effect in buffering and damping shock parts and preventing vibration.


Polyurethane is a material with better wear resistance among non-metallic materials.




Features


Feature 1: Compared with rubber, polyurethane has a wider choice of hardness, is softer and more elastic, and has a certain degree of air tightness.


Feature 2: Polyurethane is excellent in mechanical strength, and it is more widely used to prevent scratches and cracks when tightening brittle objects such as glass and acrylic.


Feature 3: Vibration and sound are not easily transmitted. Polyurethane shock absorption material


减震材料台阶型

Feature 4: Polyurethane has low dust-generating properties, and because it does not contain carbon, it is a material that is not prone to color transfer.


Feature 5: According to different working conditions, the corresponding product types are very rich.


Feature 6: Introduction to the characteristics of low resilience polyurethane


Low resilience polyurethane is more excellent in impact absorption, and also has good performance in permanent compressibility.


The disadvantage is that the tensile strength and elongation rate are low, and it is not suitable for use in high-impact conditions and low-temperature environments.


Feature 7: Introduction of Vulkollan®-Super Wear-resistant Polyurethane


■Super wear-resistant polyurethane: Vulkollan®


Vulkollan® is a super abrasion-resistant polyurethane, with abrasion resistance and load-bearing properties that previous polyurethanes did not.


The abrasion resistance is 6 times that of standard polyurethane, and the mechanical strength is 1.5 times.


When used for a long time, the heat-resistant temperature of Vulkollan® is 80℃, and when used for a short time of 15-20 minutes, it is 120℃.


■About the discoloration of Vulkollan®




Precautions


①About the discoloration of polyurethane


Polyurethane will darken its color by absorbing ultraviolet rays or illuminating light. This phenomenon is called yellowing. But it does not affect its physical properties, please fully understand when using it.


②Polyurethane hydrolysis characteristics


If polyurethane is used for a long time in a humid or humid environment, it will be hydrolyzed and deteriorated.


It is recommended to manage the temperature and humidity of the warehouse and use environment in areas with high humidity to extend the service life of the product.


③The state change of the product after hydrolysis


· Polyurethane surface becomes sticky


· Tap nails will leave irreversible scars


· Decreased polyurethane hardness


④Polyurethane size change


The size of polyurethane will change with the surrounding temperature, but the amount of change is not large, and it can be restored to its original size after a few hours at room temperature.


· Polyurethane is dry and cracked, easily disintegrated into powder


Next:None
