Since quality is our top priority, our experienced technicians utilize our state-of-the-art lab in order to monitor every aspect of production. Every batch of rubber, whether mixed in-house or from a custom mixer, is subjected to a rheometer test. In addition, tensile, compression, and aging tests are performed to confirm that the rubber being used meets the specific requirements of that particular compound. This ensures that our customers receive products that adhere to the most stringent quality guidelines.
