Long term stability testing method and evaluation criteria for PP silver plated film

brief introduction

PP silver plated filmDue to its excellent conductivity and reflectivity, it has been widely used in multiple fields. However, its long-term stability, including aging resistance and weather resistance, is a key factor determining its performance and service life. This article aims to explore the long-term stability testing methods and evaluation criteria for PP silver plated film, and to mention the contributions and expertise of Advanced Institute (Shenzhen) Technology Co., Ltd. in this field.

The stability of PP silver plated film is directly related to the reliability and durability of the product. Aging resistance and weather resistance testing are important means to evaluate the long-term stability of PP silver plated film. By simulating the environmental conditions that may be encountered during long-term use, the performance changes of materials can be predicted, providing a basis for product quality control and improvement.

Aging resistance test

The aging resistance test mainly evaluates the aging resistance of PP silver coating film during long-term use. The testing methods include:

1. Thermal aging test: Expose the PP silver plated film to a high temperature environment and observe the changes in its physical and chemical properties. The testing conditions can be set according to the actual application environment, such as lasting for weeks to months at temperatures of 70 ° C or higher.

2. Light aging test: Using artificial light sources (such as xenon lamps or ultraviolet lamps) to simulate sunlight irradiation on PP silver plated film, evaluate its stability under light exposure.

3. Chemical medium aging test: Expose PP silver plated film to a specific chemical medium, such as acidic, alkaline, or salt spray environment, to evaluate its ability to resist chemical corrosion.
