At Zhejiang Leasinder Technology Co., Ltd., quality is not just a standard—it is the foundation of everything we produce. Established in 2011 and located in Yuhang Economic Development Zone, Hangzhou City, Zhejiang Province, our company has consistently focused on delivering high-performance PS diffusion sheets, PS diffuser sheets, and a wide range of organic sheet solutions.

Recently, we conducted a visual comparison to clearly demonstrate the importance of raw material selection in our production process. The image above shows two types of PMMA (polymethyl methacrylate) particles:

Left: 100% virgin PMMA particles
Right: Recycled (crushed) PMMA particles

At first glance, the difference may seem subtle, but for professionals in the industry, the distinction is critical.

Why 100% Virgin Material Matters

Using 100% virgin PMMA ensures:

Superior Optical Clarity
Virgin materials provide consistent light diffusion and high transparency, which is essential for applications such as LED panels and lighting systems.
Stable Physical Performance
New materials maintain better mechanical strength, durability, and resistance to aging compared to recycled alternatives.
Uniform Quality Control
Recycled materials often introduce variability, impurities, and inconsistencies that can negatively impact the final product.
Enhanced Surface Finish
Products made from virgin PMMA exhibit smoother surfaces and better visual appeal—crucial for high-end applications.

In contrast, recycled PMMA particles may contain impurities, irregular shapes, and degraded properties, which can lead to defects such as uneven diffusion, reduced strength, and shorter product lifespan.

Our Promise: No Compromise on Raw Materials

At Zhejiang Leasinder Technology Co., Ltd., we strictly use 100% virgin raw materials in the production of our PS diffusion sheets and diffuser sheets. This commitment ensures that every sheet we deliver meets the highest standards of performance, reliability, and consistency.

As a professional manufacturer and factory specializing in PS diffusion sheets, we understand that material quality directly impacts end-product performance. That’s why we never compromise.
