Recently, Dajulong successfully passed comprehensive rigorous testing by the Fraunhofer IPA (German Fraunhofer Society for Applied Research) and obtained the CSM ® Cleanroom Applicable Materials Certification. Its flooring cleanliness level reached ISO Class 3, making it one of the few domestic manufacturers of resilient flooring materials holding this internationally authoritative certification. The product's robust capabilities have once again been endorsed by global professional institutions.

  CSM® Cleanroom Material Certification is a highly prestigious material certification program in the international cleanroom field, imposing stringent requirements on product indicators such as particulate release, wear resistance, and chemical corrosion resistance. Leveraging years of research and development expertise in flooring materials, Dajujun has established a comprehensive quality control system, covering raw material formula selection, automated production process management, and multiple rounds of product testing. The submitted product exhibits ultra-low particulate release performance, fully meeting the construction standards for high-grade clean spaces such as biomedical, precision electronics, and semiconductor laboratories. It addresses the challenges of particulate control in floor materials for clean environments, establishing a robust quality barrier for high-end cleanroom floor applications.

   As a benchmark brand in the domestic flexible flooring industry, Dajulong has long been dedicated to the research and development of functional floor materials, continuously targeting high-end niche markets such as medical, industrial, and transportation sectors. This focus drives the iterative upgrade of floor materials toward functionalization and high-end positioning. In the future, Dajulong will continue to leverage its technological R&D advantages, refine high-quality floor system solutions, and contribute to the high-quality development of clean engineering and supporting infrastructure in the advanced manufacturing sector within China.
