About the Material
Here’s an overview of the Rubber-Like material for Urethane Casting on the AutofabX platform, including its advantages, limitations, physical properties, design parameters, and more:
Rubber-Like Material Advantages:
Elasticity: Rubber-Like materials are highly flexible and elastic, allowing them to be used in applications that require parts to deform and return to their original shape.
High Tear Resistance: They offer good tear strength, making them ideal for parts that will be subject to mechanical wear and stress.
Excellent Impact Resistance: Rubber-Like materials absorb impact well, making them suitable for parts that will experience frequent shocks or high stress.
Vibration Damping: Due to their flexibility and elasticity, Rubber-Like materials can dampen vibrations, making them useful for noise-reducing applications or in environments where mechanical vibrations are a concern.
Low Coefficient of Friction: These materials have a lower coefficient of friction compared to many rigid plastics, making them ideal for applications involving moving parts.
Rubber-Like Material Limitations:
Lower Dimensional Stability: Rubber-Like materials can deform or change shape under heat or load over time, which can be a limitation for precision applications.
Chemical Resistance: While they offer good resistance to wear, their chemical resistance may be limited when exposed to aggressive solvents or oils, depending on the specific formulation.
Surface Finish: Achieving a smooth, glossy finish on Rubber-Like materials can be challenging, as they tend to have a more matte or textured surface.
Heat Resistance: Rubber-Like materials are not typically suitable for high-temperature applications, as they may degrade or lose flexibility when exposed to elevated temperatures (above 80-100°C).

Consumer Goods: Common in the production of flexible parts like grips, handles, and non-slip feet, which require flexibility and durability.
Medical Devices: Suitable for non-invasive medical components such as seals, grips, and soft-touch components, where flexibility and biocompatibility are important.
Electronics: Used for parts like buttons, protective covers, and dampers, offering flexibility and protection to sensitive electronic components.
Industrial Applications: Rubber-Like materials are used in industrial equipment for gaskets, seals, and protective casings, requiring high durability and flexibility under mechanical stress.
Frequently Asked Questions (FAQs):
What is the temperature range for Rubber-Like materials?
Rubber-Like materials typically perform well at temperatures between -20°C and 80°C, but prolonged exposure to temperatures above 100°C can degrade the material.
Are Rubber-Like materials resistant to oils and solvents?
Rubber-Like materials have moderate resistance to oils and solvents, but their chemical resistance may not be as high as other materials. Testing should be done for specific applications.
Can Rubber-Like materials be used for high-stress applications?
While Rubber-Like materials are excellent for applications involving flexibility and impact resistance, they are not suitable for high-stress applications requiring rigid strength. Higher-performance elastomers may be needed in such cases.
Is Rubber-Like material UV resistant?
Rubber-Like materials can degrade with prolonged UV exposure, especially if not treated or coated. Protective coatings or UV-resistant treatments should be applied for outdoor applications.
What is the demold time for Rubber-Like materials?
Demold time typically ranges from 2 to 4 hours, depending on part size, thickness, and mold design.
Can Rubber-Like materials be used for food-contact applications?
Rubber-Like materials are generally not food-safe unless explicitly specified by the manufacturer. For food-safe applications, alternative materials or specific certifications should be considered.
Rubber-Like materials are ideal for applications requiring flexibility, impact resistance, and vibration damping, but they are not suitable for high-precision or high-temperature applications. They provide excellent value for prototyping and functional parts in a variety of industries.
