Hot melt adhesive mesh is a non-woven hot melt adhesive product that can be easily operated continuously or intermittently. Widespread application
Used for bonding various fabrics, paper, polymer materials, and metal materials, with a mesh-like appearance similar to non-woven hot melt adhesive products. Hot melt adhesive mesh can be divided into PA hot melt adhesive mesh, PES hot melt adhesive mesh, EVA hot melt adhesive mesh, TPU hot melt adhesive mesh, etc. according to their composition. Different components of hot melt adhesive mesh have different physical properties, application fields, and applicable materials.
Product advantages:
1. Hot melt adhesive mesh is environmentally friendly, odorless, and solvent-free to effectively achieve clean production without causing pollution to the environment. In addition, its application also reduces the use of traditional adhesives or adhesives, further reducing the potential impact on the environment.
2. The adhesive strength of the hot melt adhesive mesh film is excellent, and it has good adhesion performance for various materials, which enables it to meet the adhesive needs of different fields and materials.
When using hot melt adhesive mesh for bonding, simply heat it up through ironing or pressing equipment to melt and bond the hot melt adhesive mesh onto the material. After cooling, the bonding can be completed. This operation method is simple and fast, which improves work efficiency.
4. Due to the mesh structure of hot melt adhesive mesh, it has good breathability, which makes it advantageous in application scenarios that require maintaining material breathability, such as clothing and shoe materials.

Application field:
In the clothing industry, whether it is outerwear, underwear, or sports equipment, hot melt adhesive mesh plays a crucial role. It can firmly bond different fabrics, substrates, and decorations together, ensuring the beauty and comfort of clothing. For example, in the production of underwear, hot melt adhesive mesh is commonly used for seamless fitting of seamless underwear, providing wearers with a seamless and comfortable experience.
In the field of shoe materials, hot melt adhesive mesh film also performs well. Whether it's sports shoes, casual shoes, or leather shoes, hot melt adhesive mesh can achieve perfect adhesion between the upper and sole, enhancing the durability and comfort of the shoes.
In addition, in the home textile fabric and home building materials industry, hot melt adhesive mesh film also plays an indispensable role. It can firmly bond home decorations such as curtains and wallpaper with substrates, improving the aesthetics and durability of home decoration.
With the development of technology, the application fields of hot melt adhesive mesh films are constantly expanding. In the automotive interior manufacturing industry, it solves the problem of pollution sources in automotive interiors; In the field of metal material bonding, it has strong adhesion to metal materials and is suitable for bonding metal materials.

How to Prevent Hot Melt Adhesive Web from Degrading Over Time in Outdoor Applications?

In the fast-evolving world of industrial materials, hot melt adhesive webs (HMAWs) have become indispensable for bonding applications across industries such as solar energy, automotive manufacturing, and outdoor textiles. However, their performance in outdoor environments—where exposure to UV radiation, temperature fluctuations, moisture, and mechanical stress is inevitable—poses significant challenges. For companies like Nantong Feiang Composite Materials Co., Ltd., a leader in advanced hot-melt adhesive solutions, addressing these challenges is critical to ensuring product longevity and customer satisfaction. 
Understanding the Causes of Degradation
Hot melt adhesive webs, typically composed of polymers like EVA, PA, PES, or TPU, are designed for strong adhesion and flexibility. However, outdoor conditions accelerate their aging through:
UV Radiation: Prolonged sunlight exposure breaks down polymer chains, leading to brittleness and loss of adhesion.
Thermal Cycling: Repeated expansion and contraction from temperature changes weaken internal cohesion.
Moisture and Oxidation: Water ingress and oxygen exposure hydrolyze or oxidize sensitive polymer bonds.
Mechanical Stress: Wind, vibration, or abrasion can physically damage the adhesive structure.
Without mitigation, these factors compromise product integrity, risking delamination, reduced bond strength, or complete failure.
Strategies for Enhancing HMAW Durability
1. Material Selection: The Foundation of Resilience
Choosing the right base polymer is the first line of defense. For example:
TPU (Thermoplastic Polyurethane): Offers superior UV resistance and flexibility, ideal for automotive interiors exposed to sunlight.
EVA with Cross-Linking Agents: Enhances thermal stability for solar panel encapsulation, where temperatures exceed 80°C.
PES (Polyester): Resists hydrolysis, making it suitable for humid environments like outdoor furniture.
Nantong Feiang’s R&D team emphasizes polymer modification—such as blending UV-stabilized resins or adding hydrophobic additives—to tailor materials for specific climates.
2. Advanced Additives: Shielding Against Environmental Stress
Incorporating functional additives significantly extends HMAW lifespan:
UV Stabilizers: Hindered amine light stabilizers (HALS) or benzotriazole derivatives absorb or scatter UV rays, protecting the polymer matrix.
Antioxidants: Phenolic or phosphite antioxidants neutralize free radicals generated by thermal and oxidative degradation.
Hydrophobic Agents: Silica nanoparticles or fluoropolymers reduce water absorption, preventing hydrolytic breakdown.
Case studies from Nantong Feiang’s solar encapsulation projects show that optimized additive blends can extend HMAW service life by 40% in high-UV regions.
3. Structural Design: Engineering for Endurance
Innovative web architecture enhances durability:
Multi-Layer Composite Structures: Combining a UV-resistant top layer with a high-adhesion core balances protection and performance.
Surface Texturing: Micro-roughened surfaces improve moisture shedding and reduce dirt accumulation, a common issue in outdoor filtration systems.
Reinforced Mesh Designs: Embedded polyester or glass fiber meshes (used in Nantong Feiang’s industrial fabrics) distribute mechanical stress, minimizing crack propagation.
4. Precision Manufacturing and Quality Control
Even the best materials fail if production processes are inconsistent. Key practices include:
Controlled Thermal Processing: Precise temperature profiles during extrusion prevent polymer degradation at the manufacturing stage.
Cross-Linking Technologies: Electron beam irradiation or chemical cross-linking (e.g., peroxides for EVA) creates a 3D polymer network, boosting heat and creep resistance.
Rigorous Testing: Accelerated aging tests (e.g., QUV weathering, thermal cycling) simulate decades of outdoor exposure to validate formulations.
Nantong Feiang’s ISO-certified labs employ ASTM and ISO standards to ensure every batch meets global durability benchmarks.
5. Application-Specific Solutions
Tailoring HMAWs to end-use scenarios maximizes performance:
Solar Panel Encapsulation: UV-stabilized EVA webs with anti-PID (potential-induced degradation) properties ensure 25-year module warranties.
Outdoor Apparel: Breathable TPU webs with moisture-wicking layers maintain adhesion in rain or sweat-prone environments.
Automotive Exteriors: PA-based adhesives with high glass transition temperatures (Tg) resist deformation under hood heat.
