MATERIAL DECOMPOSITION
Plastics are designed to offer versatility, but the same properties that make them ideal can also impact their longevity. Chemicals, in particular, play a significant role in material breakdown. When selecting blades, it’s essential to consider the specific use case to ensure both the surface being worked on remains undamaged and that the blades retain their durability without decomposing.
EDGE WEAR
Blades are crafted with an optimal scraping angle and precision edge sharpness for maximum effectiveness. However, with each stroke, the blade's edge becomes less sharp as it passes over the surface. The rate of wear is directly related to the roughness of the surface and the hardness of the substance being removed, leading to a decrease in scraping efficiency over time.
