Want to know how high-performance plastics acquire "smart" properties such as heat resistance and anti-aging? The answer lies in functional masterbatches.

In the field of new materials, "cleanliness" is not only a standard for the production environment, but also a direct reflection of technical precision and quality commitment.

In the wave of new material innovation, testing laboratories are the "touchstone" of technological breakthroughs and the "yardstick" of quality trust.

In the field of new materials, Shengding New Materials Technology Co., Ltd.'s TPU glass interlayer is knocking on the door of the global market with its combination of "hard-core performance + green logistics".

When you stand in front of a glass window filled with light and shadow, you are suddenly struck by the colorful picture, but do you know? The secret to keeping this beauty from fading away lies in a layer of glass interlayer called EVA.

Have you ever wondered, "How does bulletproof glass actually work?" Spoiler alert: It's not about magic; the key lies in that invisible laminated film. Today, we will unveil the mystery of bulletproof glass.

I just came back from an industry exhibition in Chile last week. When I was sorting through the photos, the group photos and booth photos suddenly reminded me of those vivid moments in the foreign exhibition halls.

EVA interlayer film and laminated glass equipment shine in South America, and Shengding embarks on a new international journey

In the field of building materials and home furnishings, choosing the right EVA film or TPU film requires comprehensive consideration of multiple factors such as performance, environmental protection, and cost. The following are specific selection points:

In supermarkets, the food section is always the busiest corner—freshly baked bread exudes a wheaty aroma, fresh meat in the refrigerator glows rosy, and frozen fruits and vegetables in the freezer are plump and bright. But few people realize that the hidden hero behind keeping these foods in their appetizing state is EVA film. Its highly transparent "visual window" allows for a clear indication of freshness, while its precise "freshness barrier" locks in delicious flavors, making it a key tool in boosting sales and reducing waste in supermarket food sections.

The waterproof performance of EVA film is not fixed, but is a variable controlled by material formulation, structural design, and processing technology. Its core related factors can be summarized into three dimensions. The specific parameters under each dimension directly determine the strength of the waterproof ability and are also the key basis for actual selection:

The widespread application of TPU film (thermoplastic polyurethane film) in the packaging field stems from its comprehensive performance advantages. These advantages perfectly match the packaging's multiple requirements for protection, visual presentation, ease of use, and environmental adaptability. Specifically, they can be divided into the following five categories:
