Product Features

Feature 1: Compared to rubber, polyurethane offers a wider range of hardness options, is softer and more elastic, and also has a certain degree of airtightness.
Feature 2: Urethane has excellent mechanical strength and is more widely used to prevent scars and cracks when brittle objects such as glass and acrylic are fastened.
Feature 3: Urethane is less likely to transmit vibration and sound.
Feature 4: Polyurethane has low dust generation, and since it does not contain carbon, it is a material that is not prone to color transfer. (*Natural color only)
Feature 5: A wide variety of products are available to suit different operating conditions.

Characteristics of Polyurethane, Rubber, and Sponge.
Feature 6: Available with or without shaft collar, offering multiple options to meet your needs.

Precautions

(1) About urethane discoloring
Urethane will darken its color by absorbing UV rays or illuminating light. This phenomenon is called yellowing. But it does not affect its physical properties, please fully understand when using it.

New urethane	Yellowed urethane

②Hydrolysis characteristics of urethane
If urethane is used for a long time in a moist or humid environment, it will be hydrolyzed and deteriorated.
It is recommended to manage the temperature and humidity of the warehouse and operating environment in areas with high humidity to extend the service life of the product.

(3) Changes in the state of the product after hydrolysis
· The polyurethane surface becomes sticky
· Pressing lightly with a fingernail leaves irreversible marks
· Polyurethane hardness decreases
· Polyurethane dries and cracks, easily disintegrating into powder

Hydrolyzed urethane

④Urethane dimension change
Urethane dimension will change with the surrounding temperature, but the amount of change is not large, and it can be restored to its original dimension after a few hours at room temperature.

Example of Use

Example of Use①	Role of Product
■ Positioning Mechanism	This can prevent direct contact between metal parts, and also provides shock absorption, cushioning, and noise reduction effects.

Example of Use②	Role of Product
■ Feeding Equipment	Fits over protruding parts of equipment to prevent injury. Can also be used as a stopper to support the panel when it is flipped up.

Example of Use③	Role of Product
■ Wire Conveyance Mechanism	Utilizes the wear resistance of polyurethane Can be used as a wire guide.
