Rubber and plastic are collectively referred to as rubber and plastic industries. They are both byproducts of petroleum. They have the same source, but in the process of making products, their physical properties are different, and their uses are even more different. Rubber is widely used in tires, and plastics are becoming more and more widely used with the needs of technology and the market. They are already indispensable in daily life. Lixian develops and produces modern testing equipment according to ISO, ASTM, DIN and other rubber and plastic industry standards, providing testing basis for rubber and plastic product manufacturers and quality inspection departments.
