【Core Tip】​ As fire safety receives increasing attention across society today, a new type of flame-retardant mesh composed of high-strength polyester yarn and PVC (polyvinyl chloride)​ is rapidly gaining traction in construction, industry, agriculture, and other fields. Leveraging its exceptional fire resistance, excellent physical properties, and broad environmental adaptability, it provides innovative solutions for building a multi-dimensional fire prevention system.

【Technological Breakthrough: Advantages of Composite Materials】​ Traditional single-material flame-retardant meshes often have shortcomings in strength, weather resistance, or environmental friendliness. This industry-renowned new flame-retardant mesh innovatively adopts a "high-strength polyester yarn + PVC"​ composite structure:

High-Strength Skeleton:​ Industrial-grade high-strength polyester yarn serves as the woven base, endowing the mesh with extremely high tensile strength and tear resistance. It can withstand long-term stretching and mechanical stress in harsh environments, ensuring long-term structural stability.

Fireproof Coating Layer:​ The polyester yarn structure is uniformly coated or tightly combined with specially formulated flame-retardant PVC material. When exposed to open flames, this PVC layer rapidly expands and carbonizes, forming a dense, heat-insulating carbonized layer that effectively isolates oxygen and blocks flame spread and high-temperature transfer.

This is akin to equipping the flame-retardant mesh with "reinforced steel" and "fireproof armor."​ The polyester yarn provides "unbreakable" flexibility, while the flame-retardant PVC offers "impenetrable" protection. Their synergy achieves a 1+1>2 effect.

【Diverse Specifications, Adapting to Full-Scenario Needs】​ To meet the refined requirements of various application scenarios, this composite flame-retardant mesh has developed a rich product matrix. Taking mainstream product specifications as an example (see attached table), it demonstrates strong customization capabilities:

Refined Protection:​ The product's "mesh count"​ (number of holes per square inch) ranges widely from 800 to 2000 meshes. High mesh counts (e.g., 1200–2000 meshes) feature extremely fine structures, effectively blocking sparks, splashes, and small insects. They are suitable for precision instrument workshops, high-end warehouses, data centers, and other places requiring high fire safety and cleanliness standards.

High-Strength Heavy-Duty Protection:​ The grammage (weight per unit area)​ varies from 100 gsm to 400 gsm. High grammage models (e.g., 260 gsm and above) offer significantly increased thickness and strength, specifically designed for industrial environments like petrochemical parks, power facilities, and mines, where there is a potential risk of high-intensity flame impact.

Multifunctional Integration:​ Through process adjustments, some models also incorporate notable shading rates, enabling simultaneous fire prevention, sunshade, and dustproof functions in warehousing, logistics, agricultural greenhouses, and other fields. Colors such as dark green, charcoal gray, and navy blue are also available, balancing functionality with architectural aesthetics.

【Wide Applications, Safeguarding Key Areas】​ Currently, this type of flame-retardant mesh has been applied in several national key projects and public welfare initiatives:

Construction Field:​ Used as fireproof sealing material for cable shafts and pipeline shafts in high-rise buildings, as well as a protective layer for external wall insulation systems, effectively delaying vertical and horizontal fire spread.

Industrial Field:​ Employed for fire separation between factory buildings, equipment enclosures, and isolation curtains in hazardous material storage areas, serving as critical industrial fire barriers.

Public Facilities:​ Installed in ventilation ducts of subway tunnels, underground parking garages, and large shopping malls to prevent fire spread through air ducts.

Emerging Fields:​ Deployed around new energy vehicle charging stations and outdoor energy storage stations as fire isolation belts, enhancing safety margins for emergency response.

【Market Prospects and Industry Outlook】​ With increasingly stringent national work safety regulations and growing public awareness of safety, the demand for flame-retardant materials continues to rise. Industry experts point out that the "high-strength polyester yarn and PVC composite flame-retardant mesh"​ represents an important trend in flame-retardant materials toward high performance, lightweight, multifunctionality, and ease of construction. Its successful application not only enhances the effectiveness of passive fire protection systems but also provides new insights for upgrading China's fire safety industry. In the future, with further breakthroughs in material technology, next-generation products such as smart flame-retardant meshes (e.g., integrated with temperature-sensing alarm functions) are already under development. The fire safety network is evolving toward smarter and more reliable directions.
