Certain applications require the utmost performance from their individual components. Natural rubber is a versatile material that has been utilized in engineering for many years, and for a straightforward reason—it can endure significant stress while still fulfilling essential functions.
Natural rubber boasts high tensile and tear strength, along with exceptional resistance to fatigue. These robust characteristics render it an ideal polymer for both dynamic and static engineering applications that encounter frequent vibration, noise, contact, and other challenges. Consequently, natural rubber is a suitable solution for tires, printer rollers, agitators, and various parts that regularly engage with abrasive surfaces or other potentially damaging elements.
