Qingdao Kingstone Industry Co., Ltd. Announces Rigorous Test Results for Dust Control Mat

In the design of commercial and public spaces, an entrance mat is not just the first impression but a critical line of defense for indoor safety, cleanliness, and professional image. Qingdao Kingstone Industry Co., Ltd. understands this significance and is committed to crafting benchmark products with cutting-edge technology and stringent standards. Today, we are proud to share with the industry the latest internal test results of our flagship product—the commercial entrance mat featuring a nylon surface and rubber base. Its exceptional durability and top-tier safety performance once again redefine industry quality standards.

1. Extreme Durability: 300 Industrial Wash Cycles, Lasting Like New

To simulate high-intensity commercial use, we subjected the mat to **300 consecutive standard industrial washing cycles in our in-house testing laundry facility. The results confirm outstanding performance even under such demanding cleaning conditions:

Zero Shrinkage: Mat dimensions remained perfectly stable with no noticeable shrinkage or deformation.

Structural Integrity: The nylon surface fibers showed no signs of wear, pilling, or shedding. The underlying rubber retained its original grip and elasticity, with no cracking or hardening.

Uncompromised Function: Core functions of scraping dirt, trapping dust, and absorbing moisture remained undiminished.

What This Means: For venues requiring frequent deep cleaning—such as hotels, office buildings, hospitals, and shopping malls—our mat can withstand the test of time and rigorous maintenance. This significantly extends replacement cycles, reduces long-term operational and maintenance costs, and truly delivers "one investment, long-term peace of mind."

2. Superior Anti-Static Properties: Creating Safety for Sensitive Environments

Static buildup is not only uncomfortable in dry environments but can also pose potential risks to precision electronic equipment or specific industrial settings. Our mat's anti-static properties were rigorously tested in accordance with the authoritative German standard DIN 54345-1:1992 (Testing of Textiles – Electrostatic Behaviour).

The Test: This standard measures surface resistivity, a key indicator of a material's ability to dissipate electrostatic charge. A lower value indicates better anti-static (conductive) performance.

Our Result: The test yielded an excellent result of 1.78 × 10¹¹ Ω (Ohms), demonstrating our mat's outstanding electrostatic dissipation capability.

Practical Value: In static-sensitive areas like data centers, laboratories, electronics manufacturing workshops, and hospital operating room corridors, using our mat effectively reduces the risk of human body static accumulation and sudden discharge, adding a crucial layer of safety for personnel, equipment, and sensitive processes.

3. High-Standard Fire Resistance: Elevating Space Fire Safety

Fire safety is paramount. Our product's fire resistance has been assessed and authoritatively recognized according to the core EU standard for construction product fire safety, EN 13501-1:2018.

The Standard Explained: EN 13501-1 is a classification system for the fire performance of floor coverings. Within it, the classification "Dfl" evaluates the flammability of floor products, and "s1" signifies very limited smoke production during combustion.

Our Classification: The product has achieved the **Dfl-s1** classification.

Practical Value: This means that in the event of an accidental fire, our mat is resistant to flame spread and produces minimal smoke. The low-smoke characteristic helps maintain clearer visibility for safer evacuation, effectively enhancing the overall fire safety level of entrance areas in commercial and public buildings and meeting high-standard building codes and safety management requirements.

About the Product: The Qingdao Kingstone Industry Co., Ltd. Dust Control Mat is manufactured using a composite process of high-density, wear-resistant nylon surface and high-grip, eco-friendly rubber backing. It combines efficient dirt removal, durability, easy cleaning, and safety protection, making it an ideal solution for premium commercial space entrances.

About Us: Qingdao Kingstone Industry Co., Ltd. steadfastly adheres to the philosophy of "Validating Quality through Testing, Driving Development through Innovation." We not only submit products to third-party laboratories but have also established a comprehensive internal testing system to ensure every mat can withstand the rigors of real-world environments. Our laundry facility and testing lab are testaments to this commitment.

The announcement of these test results fully demonstrates Qingdao Kingstone Industry Co., Ltd.'s dedication to being accountable for the lifelong performance of our products. We offer not just a product, but a professional promise of safety, durability, and reliability.
