Company Introduction

Product Advantages and Selling Points

• Self – Produced Raw Materials: As mentioned earlier, the company’s advantage of self – produced raw materials brings multiple benefits. It can strictly control the quality of raw materials, avoiding quality fluctuations caused by external suppliers. From the initial selection of raw material components to the final production of raw materials, the company implements strict quality monitoring to ensure that every batch of raw materials meets its high – quality standards. This provides a solid foundation for the quality of the Hot Melt Pressure Sensitive Adhesive. Additionally, self – produced raw materials enable the company to optimize the production process and reduce production costs. These cost savings are passed on to customers, making the company’s products more competitive in the market. Customers can enjoy high – quality adhesive products at more favorable prices.
• Excellent Adhesive Properties: Hot Melt Pressure Sensitive Adhesive has outstanding adhesive properties. Its strong initial tack allows it to adhere quickly to substrates with minimal pressure. The high bond strength ensures that bonded products can withstand external forces without easy detachment. Whether it’s smooth surfaces like glass and metal or porous materials like paper and fabrics, it can provide reliable adhesion. In practical applications, such as labeling operations in the packaging industry, it can ensure that labels stick firmly to product packaging and remain stable during transportation and storage without falling off or curling.
• Wide Temperature Resistance Range: The adhesive demonstrates excellent performance in different temperature environments. At high temperatures, it does not soften, flow, or lose adhesion. At low temperatures, it does not become brittle or crack, maintaining good flexibility and adhesion. This makes it suitable for products used in various temperature conditions. For example, in cold chain logistics packaging, it can ensure the stability of package sealing under low – temperature environments; in high – temperature environments such as near heat sources, it can maintain the firm adhesion of labels and other bonded parts.
• Good Chemical Resistance: The adhesive has good resistance to chemicals such as water, oil, and organic solvents. It does not easily swell, dissolve, or degrade when exposed to these substances, ensuring the long – term stability of the bonded products. In practical applications, such as in the food packaging industry, it can withstand the erosion of oils and moisture from food, maintaining the integrity of the packaging; in industrial applications, it can resist the effects of various chemicals, ensuring the normal use of bonded components.
• Customizable Formulation: Adhesive(Shanghai)Co.Ltd can provide customized formulations based on customers’ specific requirements. Whether it’s adjusting the adhesive’s viscosity, peel strength, or temperature resistance, the company’s professional R&D team can develop suitable adhesive formulations to meet the diverse needs of different customers and applications.

Production Process

• Raw Material Preparation: Raw materials are accurately weighed according to the predetermined formulation and placed into the reactor. The company’s raw material warehouse is strictly managed to ensure the quality and specifications of raw materials meet production requirements. During the weighing process, precision instruments are used to ensure the accuracy of raw material quantities, providing a guarantee for the stability of the adhesive’s quality.
• Melting and Mixing: The raw materials are heated and melted in the reactor, then thoroughly mixed through stirring to ensure uniform composition. The company’s advanced heating and stirring equipment can precisely control the temperature and stirring speed, enabling the raw materials to melt and mix fully. This ensures the uniformity of the adhesive’s performance.
• Degassing: After melting and mixing, the adhesive mixture undergoes degassing treatment to remove air bubbles within it. This prevents the formation of bubbles during application, which could affect adhesion. The company’s degassing equipment uses advanced vacuum degassing technology to effectively remove air bubbles and improve the quality of the adhesive.
• Application and Cooling: The degassed adhesive is applied to the substrate through application equipment and cooled to solidify. The company has various application equipment, such as coating machines and spray machines, capable of meeting different application requirements. During the cooling process, the temperature is strictly controlled to ensure the adhesive solidifies completely and forms a firm bond with the substrate.
• Quality Inspection: The produced adhesive undergoes comprehensive quality inspection. The company’s quality inspection team uses advanced testing equipment and methods to test the adhesive’s viscosity, peel strength, temperature resistance, and other performance indicators. Only products that pass all quality inspections are shipped to customers.

Applications

• Packaging Industry: Used for self – adhesive labels, tape, and flexible packaging. It can ensure the firm sealing of packaging and the stable attachment of labels, enhancing the appearance and protection of packaging.
• Hygiene Products Industry: Applied in sanitary napkins, diapers, and adult incontinence products. Its strong adhesion and skin – friendly properties can securely fix hygiene products to the body without causing skin irritation.
• Electronics Industry: Used for fixing electronic components, cable fixation, and display assembly. It can provide reliable adhesion in electronic products, ensuring the normal operation and stability of components.
• Automotive Industry: Applied in automotive interior decoration, parts fixation, and sealing. It can withstand the vibrations and temperature changes in automotive environments, ensuring the firm bonding of automotive components.
