The produced glue realizes reliable fixation of functional components without causing irritation, perfectly matching the mass production needs of hygiene product manufacturers.

Packaging Industry Adhesive for Sealing & Fixation

It is widely used in producing HMPSA pillow glue for the packaging industry, mainly for sealing courier bags, various packaging bags and bonding sealing tapes. The adhesive manufactured by this reactor features strong initial adhesion and long-term bonding stability, effectively preventing package leakage and loosening during transportation and storage. It adapts to high-speed packaging production lines, greatly improving the efficiency of logistics and commodity packaging operations.

Special Adhesive for PET Labels & Milk Straws

The reactor is specially optimized for producing HMPSA pillow glue for light industrial packaging accessories, such as PET water bottle labels and milk straws. The adhesive has excellent moisture resistance and temperature adaptability, ensuring that water bottle labels do not fall off in wet environments and milk straws maintain firm bonding under low-temperature storage conditions. It supports the production of food-grade compliant adhesives, fully meeting the quality requirements of the food and beverage packaging sector.

Elastic Adhesive with High Performance Resistance

It is dedicated to the production of high-performance elastic HMPSA pillow glue, which is characterized by ultra-high creep deformation resistance and rebound resilience. This adhesive is suitable for scenarios requiring repeated stretching and recovery, such as elastic packaging tapes, flexible industrial parts bonding and disposable hygiene product elastic components. The reactor’s precise mixing and temperature control ensure the uniform distribution of elastic components, maximizing the product’s performance stability.

Automotive Interior & Trim Bonding

HMPSA pillow glue produced by this reactor is also used in automotive interior applications, such as bonding door panels, dashboard trim, and carpet liners. It offers excellent heat resistance and vibration damping properties, ensuring durable adhesion even in extreme temperature fluctuations common in vehicle interiors.

Textile & Non-woven Fabric Lamination

The reactor supports the production of HMPSA pillow glue for laminating textiles and non-woven fabrics, used in products like disposable medical gowns, protective masks, and furniture upholstery. The glue provides flexible, breathable bonding that maintains the integrity of the fabric while meeting the stringent safety standards of medical and home textile industries.

Electronics Component Encapsulation

It is employed to manufacture HMPSA pillow glue for encapsulating and sealing delicate electronic components, such as circuit board modules and sensor housings. The adhesive offers superior electrical insulation and shock absorption, protecting sensitive electronics from moisture, dust, and mechanical impact.

Pre-Operation Inspection & Preparation

Conduct a comprehensive check of the SS304/316L reactor: verify the integrity of the jacketed heating/cooling pipeline, confirm the stirring motor and seal ring are intact, and calibrate the temperature controller to ensure ±1°C accuracy. Weigh HMPSA raw materials per the formula, preheat solid resins to reduce melting time, and ensure the discharge valve is closed tightly before feeding.

Raw Material Feeding & Initial Heating

Open the sealed feeding port and add pre-weighed raw materials in sequence (polymer base, tackifier, plasticizer). Close and lock the feeding port to form a closed reaction system. Start the low-speed stirring (50-80 rpm) and activate the jacketed heating system, raising the temperature at a rate of 5°C/min to avoid raw material carbonization.

Reaction & Homogenization Control

When the temperature reaches the set value (typically 120-160°C for HMPSA), adjust the stirring speed to 120-180 rpm for full homogenization. Monitor the viscosity and reaction state in real time via the sight glass; maintain the temperature stably for 30-60 minutes. For elastic adhesive production, extend the mixing time to ensure uniform dispersion of elastic components.

Cooling & Discharging

After the reaction is complete, switch to the jacketed cooling system and lower the temperature to 80-100°C at a controlled rate. Reduce stirring speed to 30-50 rpm to prevent bubble generation. Open the discharge valve and transfer the finished HMPSA pillow glue to the storage tank or packaging equipment for subsequent processing.

Post-Production Cleaning & Maintenance

Rinse the reactor inner wall with hot solvent (matching HMPSA type) while stirring at low speed to remove residual glue. Wipe dry with a clean cloth and inspect key parts: lubricate the stirring shaft bearing, check the seal ring for wear, and record the operation parameters and maintenance status for future reference.
