Polyurethane gasket

Product Name: Polyurethane Washer

Polyurethane washers have good effects in preventing scratches and cracks of the workpiece during tightening; shock absorption and vibration reduction and anti-vibration.

The transparent polyurethane has a special effect which is more inconspicuous when used as an appearance part.

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 very excellent in mechanical strength, and it is widely used to prevent scratches and cracks when tightening brittle objects such as glass and acrylic.

Feature 3: It is not easy to transmit vibration and sound, and it can be used when tightening screws to achieve a certain degree of cushioning and tightening effect.

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. Round silicone gasket

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

Feature 6: Introduction of Vulkollan®-Super Wear-resistant Polyurethane

Super abrasion resistant polyurethane: Vulkollan®

Vulkollan® is a super abrasion-resistant polyurethane, which has the abrasion resistance and loadability that the previous polyurethane shrinkage does not have.

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 degrees, and when used for a short time of 15 to 20 minutes, it is 120 degrees.

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 on your nails will leave irreversible scars

·Polyurethane hardness decreased

·Polyurethane is dry and cracked, easily disintegrated into powder

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.
