OGD-51A Professional Filter Hot Melt Adhesive Pellets for Non-Woven Fabrics

Name: OGD-51A Professional Filter Hot Melt Adhesive Pellets for Non-Woven Fabrics
Brand: OUGUDE

OGD-51A is a white, non-toxic, hot-melt adhesive in granular form, custom-engineered for the lamination process of non-woven fabrics and filter paper in various types of filters. It is suitable for the entire manufacturing process, including filter paper pleating and forming, bonding between filter frames and filter paper, and frame filling and sealing. The adhesive features excellent fluidity, high bond strength, moderate curing speed, and stable bonding performance in low-temperature environments. With an open time of 8 to 12 seconds and a curing time of 10 to 15 seconds, it provides ample time for alignment and positioning, making it compatible with automated production lines for air, water purification, and other filtration consumables. It offers storage stability, making it an eco-friendly adhesive specifically tailored for the filtration industry.

Description

I. Precautions

1. The molten adhesive is at a high temperature; wear high-temperature resistant protective gear throughout the operation to prevent high-temperature burns.

2. Mixing with other models of hot melt adhesives (such as those for cartons or EPE foam) is strictly prohibited to avoid performance alterations that could affect filtration sealing efficiency.

3. Store materials in designated zones, keep them away from children, and prevent accidental contact or ingestion.

4. For complete safe operation guidelines, please refer to the corresponding MSDS (Material Safety Data Sheet).

II. Core Advantages

1. Full-Process Adaptation for Filtration Consumables: A single adhesive covers three core processes—filter paper pleating, filter paper-to-frame bonding, and frame filling/sealing—reducing multi-model inventory costs for factories.

2. Excellent Flowability with Superior Filling & Sealing Effects: Melts smoothly and thoroughly fills gaps in filter frames without voids, enhancing the filtration barrier and dust-proof performance of the filter.

3. Stable Bonding Across High & Low Temperatures with Strong Weather Resistance: Outstanding low-temperature performance ensures the bonding layer does not crack or peel under temperature fluctuations, adapting to long-term operating conditions in air conditioners and water purification equipment.

4. Generous Operating Window to Reduce Defect Rates: Features an 8-12 second open time and a 10-15 second curing time, providing sufficient adjustment and alignment time for both manual and semi-automatic equipment to minimize false bonds and misaligned rejects.

5. Clean, White, and Non-Toxic, Suitable for Clean Filtration Products: White pellets free from yellow staining pollution, non-toxic and odorless, complying with hygiene production standards for air purification and drinking water filters.
