Tungsten Carbide MDO Stretching Roller

Tungsten Carbide MDO Stretching Roller for Bi-oriented Film Introduction of Tungsten Carbide MDO Stretching Roller for Bi-oriented Film:   Tungsten Carbide Stretching Roller For BOPP Film are commonly used in the production of BOPP (Biaxially Oriented Polypropylene), BOPET, BOPA films. These rollers play a crucial role in the stretching process, where the film is elongated in both the machine and transverse directions to improve its mechanical properties and performance.   Features and Benefits of Tungsten Carbide MDO Stretching Roller for Bi-oriented Film:   1. Material: Tungsten carbide is a highly durable and wear-resistant material, making it ideal for the demanding conditions of BOPP film stretching. 2. Hardness: Tungsten carbide rollers have a high hardness level, typically ranging from 85 to 95 HRA (Rockwell A scale), which ensures excellent resistance to wear and abrasion. 3. Surface Finish: The surface of tungsten carbide rollers is carefully engineere…
