2. Woodworking industry
Industrial hot melt adhesive is widely used in the woodworking industry. Whether it is a home woodworking project or a large industrial application, industrial hot melt glue is considered a first-class woodworking glue choice.
The main uses of hot melt adhesive in the woodworking industry include:
● Product assembly: Industrial hot melt glue is widely used in the assembly process of woodworking products, which can provide fast and strong bonding effects, especially suitable for the manufacture of small furniture and wooden frames.
● Lamination: When laminating wood and veneer materials, industrial hot melt adhesive can effectively bond different surface materials such as thin wood boards, decorative papers and fiberboards.
● Sealing and labeling: Industrial hot melt glue is also used for sealing, surface treatment and label bonding of wood products. It can cure in seconds to ensure an efficient workflow.
The advantages of industrial hot melt glue in the woodworking industry are its easy operation, fast curing speed, and the ability to quickly bond wood at room temperature, reducing waiting time during the production process.
3. Electronics industry
The assembly, packaging and sealing of electronic products are another major application area of industrial hot melt glue. As electronic equipment develops towards miniaturization and integration, the use of industrial hot melt adhesive is also increasing, especially in the production process of mobile phones, home appliances, automotive electronics and other products.
The role of hot melt adhesive in the electronics industry is mainly reflected in:
● Assembly: In the assembly of parts of electronic products, industrial hot melt glue can be used to fix components and provide fast and strong bonding effects.
● Sealing and waterproofing: Electronic equipment usually requires waterproof sealing in certain parts, and industrial hot melt glue can provide effective protection in these key parts.
● Fixing and insulation: Industrial hot melt glue can also be used for insulation and fixing of components to prevent vibration and improve durability.
The requirements for industrial hot melt adhesive in the electronics industry are high, especially in terms of temperature resistance, impact resistance and electrical insulation performance.
4. Automotive industry
In the process of automobile manufacturing, industrial hot melt glue is used to bond interior parts, seal waterproof strips, install glass, repair external plastic parts, etc.
The application of hot melt glue in the automotive industry has the following advantages:
● Efficient bonding: In automobile production, industrial hot melt glue can quickly bond parts of different materials to improve assembly efficiency.
● Temperature resistance: Industrial hot melt adhesive can withstand temperature changes in the internal and external environment of the car and maintain bonding strength.
● Anti-seismic performance: Industrial hot melt glue has certain anti-seismic performance, which can effectively reduce the impact of vibration on parts during driving.
The automotive industry has diversified demands for industrial hot melt glue, requiring it to have good bonding performance, as well as certain temperature resistance and impact resistance.
5. Textile and footwear industry
Industrial hot melt glue is widely used in the textile and footwear industry, mainly used for bonding of soles, bonding of clothing and home textile products, and processing of other fabrics.
The application advantages of hot melt glue in the textile and footwear industries are as follows:
● High bonding strength: Industrial hot melt glue can provide strong bonding, especially for high-strength bonding of footwear and clothing.
● Easy processing: Since industrial hot melt glue has a short curing time, it can greatly improve production efficiency and reduce waiting time.
● Environmentally friendly: Industrial hot melt glue has no solvent components and meets the environmental protection requirements in the textile production process.
How to choose EVA and pur hot melt glue?
Among the many types of industrial hot melt adhesives, EVA (ethylene-vinyl acetate copolymer) and PUR (polyurethane) industrial hot melt glue are two common types of industrial hot melt glue. They each have different characteristics and application scenarios. Understanding their advantages and disadvantages and applicable fields will help choose the appropriate type of industrial hot melt glue.
1. EVA hot melt glue
EVA hot melt glue is composed of ethylene and vinyl acetate copolymers, and is usually transparent and flexible. The main features of EVA hot melt glue include:
● Low cost: Compared with pur hot melt glue, EVA hot melt glue has a lower production cost and is suitable for the mid- and low-end markets.
● Fast curing: EVA hot melt glue has a faster curing speed and is suitable for efficient production environments.
● Wide applicability: EVA hot melt glue can bond a variety of substrates, such as paper, plastic, wood, etc., and is widely used in packaging, woodworking, stationery and other industries.
● Poor temperature adaptability: EVA hot melt glue has poor temperature resistance and can generally only withstand lower working temperatures (usually between 60-70°C). In high temperature environments, the bonding strength of EVA hot melt glue will decrease.
Therefore, EVA hot melt glue is most suitable for applications that do not require high bonding strength and have low working temperatures, such as paper product packaging, toys, stationery and other industries.
2. Pur hot melt glue
Pur hot melt glue is made of polyurethane material, has strong adhesion and good temperature resistance, and is particularly suitable for applications that need to withstand higher temperatures and larger loads. The main features of pur hot melt glue include:
● High bonding strength: Pur hot melt glue can provide very strong bonding after curing, and is suitable for applications requiring high-strength bonding.
● Good temperature resistance: Pur hot melt glue can maintain good bonding performance at higher temperatures and is suitable for bonding in high-temperature environments.
● Strong moisture and chemical resistance: Pur hot melt glue has strong resistance to moisture and chemicals and is suitable for occasions that require moisture resistance or corrosion resistance.
● Higher cost: Compared with EVA hot melt glue, pur hot melt glue has a higher cost and is usually used for high-end products and applications requiring high-performance bonding.
Pur hot melt glue is usually used in industries such as automobiles, electronics, and construction that have high requirements for bonding strength and temperature resistance, and is especially suitable for bonding automotive interiors and electronic components.
Therefore, for applications that require fast curing and low cost, EVA hot melt glue is undoubtedly an ideal choice; while for applications that require high bonding strength and temperature resistance, pur hot melt glue is more suitable. Choosing the right industrial hot melt adhesive according to different process requirements and industry needs can ensure the maximum production efficiency and product quality.
