EA5816-4 PUR Adhesives for Refrigerator

The Advantages of Our Refrigerator PUR Adhesive

1. Strong & Elastic Sealing

Our PUR adhesive forms resilient bonds that withstand repeated door opening and closing as well as daily mechanical vibration. With peel strength reaching 10–18 N/cm, it helps maintain long-term sealing integrity for refrigerator assembly.

2. Excellent Low-Temperature & Humidity Resistance

Engineered for refrigeration environments, the cured adhesive performs reliably at temperatures as low as –30°C and under high humidity conditions. It helps resist condensation-related failure and reduces the risk of insulation foam degradation.

3. Broad Material Compatibility

Suitable for bonding ABS/HIPS interior liners, PVC or vinyl door gaskets, polyurethane foam, metal shelves and frames, as well as plastic trim and decorative components. It supports both structural bonding and sealing functions in modern refrigerator production.

4. High Efficiency for Automated Assembly

The adhesive is compatible with automated dispensing systems and high-speed production lines. It helps improve assembly efficiency while replacing traditional mechanical fasteners and solvent-based adhesives for a cleaner manufacturing process.

5. Eco-Friendly & Appliance-Ready

This solvent-free PUR adhesive features low VOC emissions and is aligned with ecological requirements such as NSF and REACH. It helps manufacturers improve product aesthetics, production safety, and environmental compliance.

Key Process Description

1. Heating & Melting

The PUR adhesive is heated to the recommended operating temperature to obtain stable flowability for refrigerator component bonding and sealing applications.

2. Precise Adhesive Application

It is applied evenly onto the target surface by automated dispensing or coating equipment, ensuring clean adhesive distribution on liners, gaskets, panels, and structural parts.

3. Fast Assembly & Initial Bonding

During refrigerator assembly, the adhesive provides fast initial tack to secure the bonded parts quickly and support efficient positioning on high-speed production lines.

4. Moisture-Curing Crosslinking

After application, the adhesive reacts with ambient moisture to form a durable 3D cross-linked thermoset structure. Once fully cured, the bond delivers long-term resistance to cold, humidity, and repeated mechanical stress.

Benefits in Refrigerator Assembly

Door Seal Bonding

Ideal for bonding PVC or vinyl gaskets to refrigerator doors, ensuring durable elastic sealing and long-term resistance to repeated opening and closing cycles.

Foam-in-Place & Insulation Sealing

Supports refrigerator insulation systems by improving sealing performance around foam-filled structures and reducing the risk of cold loss or moisture-related failure.

Inner Liner & Decorative Component Assembly

Suitable for mounting interior liners, decorative panels, trim parts, and related structural components while improving appearance quality and assembly stability.
