Novathane Polyurethane is a cast elastomer with the versatility to be molded in a wide range of techniques and properties for improved product performance across many applications.
ADVANTAGES OF POLYURETHANE
- Versatility in hardness levels
- Abrasion and wear resistance
- High impact tolerance
- Wide temperature range
- High elasticity
- Noise and vibration reduction
- Tear resistance
- High tensile strength
Unlike rubbers, high hardness polyurethane can be just as resilient as softer materials. In shock absorbing applications, low rebound compounds are usually used in the range of 10-14%. In high frequency vibrations or where quick recovery is needed, compounds of 40-65% resilience are used.
In general, toughness is enhanced by resilience.
Polyurethane can be used in a wide range of temperatures. When exposed to freezing temperatures they remain quite flexible, are resistant to thermal shock, and can withstand sudden temperature drops without cracking.
When your component must endure a compressive load, this becomes an important property to account for, and Novathane can create a custom solution to fit your needs.
Novathane polyurethane elastomers can be altered for a hardness level ranging from 10-15 Shore A to over 80 Shore D.
Resistance to tearing when tension is applied determines tear strength. Tear strength, along with tensile strength, is critical to predicting an elastomer’s working strength in demanding applications.
Novathane Polyurethanes resist a broad range of liquids such as oil, grease, and chemicals.
Products made from Novathane Polyurethane can be formulated with additives for flame resistance as needed.
Conventional plastic materials can become brittle and weak over time. Unlike plastic, Novathane Polyurethanes remain elastic and resist fracture. This amount of toughness makes polyurethanes ideal for parts that have to hold against high impact or repeated impingement.
Novathane Potting Polyurethanes are excellent insulators. They are used extensively in potting and encapsulating applications, as well as other areas where electrical isolation is vital.
Special formulations are available for sound-deadening and anti-vibration applications. These generally have low resilience.
In many applications of polyurethane elastomers, good resistance to abrasion, and low coefficient of friction are essential characteristics.
In comparison to rubber, plastics, and even some metals, Novathane Polyurethane elastomers have a definite wear advantage.
Novathane can utilize FDA approved materials for both wet and dry food in food processing industries.
Polyurethane can be manufactured for any customer color requirements.
Coefficient of Friction
The lowest coefficients of frictions are achieved with high hardness formulations. Additives can also increase the COF to achieve a comparable UHMW solution adding toughness to your application.
Novathane Polyurethane exhibits a high tensile strength when compared to other elastomers, making it less likely to fail in abrasive environments.
