Shock-absorbing briquette

Product Name: Shock Absorbing Press Block

It is mainly used in the flexible fixation of workpieces. The polyurethane part at the front provides elastic pressing force. At the same time, it is also widely used as a limit stop.


Feature 1: Polyurethane maintains excellent mechanical strength while having elasticity. When pressing the soft surface of the workpiece, it is not easy to leave indentation or even damage the surface of the workpiece.

Feature 2: Polyurethane is sintered on the surface of the metal core. Compared with press-in adhesive products, it can provide higher polyurethane adhesion and is more suitable for use scenarios where the direction of force is more complicated.

Feature 3: Polyurethane sintered products are not easy to transmit vibration and sound. External thread type polyurethane briquette

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 usage scenarios, a variety of hardnesses are available.

Shock-absorbing briquette


① When using ester polyurethane, please do not use it in high humidity or water. This will cause hydrolysis of the polyurethane.

②About 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.

③Polyurethane 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.

④The state change of the product after hydrolysis

·Polyurethane surface becomes sticky

·Tap on your nails will leave irreversible scars

·Polyurethane hardness decreased

·Polyurethane is dry and cracked, easily disintegrated into powder

⑤Dimensional changes of polyurethane

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.
