  In industrial manufacturing, particularly in sectors like electronics, automotive, photovoltaics, and new materials, a specialized term is frequently heard—the “Double 85 Test.” This test, which might sound somewhat enigmatic, is an indispensable part of modern product quality and reliability verification. The core equipment tasked with executing this critical procedure

In our daily lives, we often observe scenes like this: dewdrops on lotus leaves are crystal clear, like rolling pearls, while water droplets spread out into a film on a glass surface. Behind this lies a crucial concept in surface science—the Water Contact Angle (WCA). It is not only an

 ZL-5006 Martindale tester is a standardized method for assessing a material’s durability, abrasion resistance, and overall wear performance. During the test, a rotating disk fitted with an abrasive medium—such as sandpaper, wire mesh, or worsted wool—moves in a figure-eight motion across the material’s surface. The number of cycles completed before

As critical components for power transmission and signal communication, the combustion performance of wires and cables directly impacts safety during fire incidents. These products are ubiquitous in various buildings, transportation vehicles, and industrial facilities. In the event of a fire, their burning rate, smoke emission, and toxic byproducts significantly affect evacuation and rescue

ZL-3047A Differential Scanning Calorimetry (DSC) is an analytical technique used to measure the heat released or absorbed by a sample during heating or cooling over a specific temperature range. In addition to characterizing the thermal properties of materials, DSC is also employed to determine the temperatures at which specific phase
