Shenzhen Tongde New Materials Technology Co., Ltd. (TONGDE / Devote) will showcase three core hot melt adhesive products at Filtech 2026, delivering more efficient and cost-effective bonding solutions for the global filtration industry.

3031BD Low VOC Polyolefin Hot Melt Adhesive: Ideal for Air Filter Edge Sealing

For the rapid automated production of automotive cabin air filters, 3031BD polyolefin hot melt adhesive offers the ideal solution. The product features ultra-low odor and delivers excellent bonding performance on filter media and edge strips. During application, the adhesive does not sag, ensuring stable and reliable edge bonding while significantly boosting production line efficiency.

Core Advantages:

• Low VOC and low odor; meets in-vehicle air quality requirements.

• The filter paper and edge strip exhibit strong adhesive bonding, ensuring a secure fit.

• Non-drip; compatible with high-speed automated edge bonding

• Heat resistant 100–110°C

3061 Series Industrial Hot Melt Foam Adhesive: Significantly Reduces Glue Costs

The 3061 series utilizes supercritical gas foaming technology with a foaming rate exceeding 40%, significantly reducing adhesive consumption and production costs without compromising bond strength. The resulting foam exhibits enhanced flexibility, making it ideal for applications such as circular filter gaskets and wire winding processes.

Core Advantages:

• Foam expansion ratio > 40%, significantly reducing adhesive usage

• Reduce adhesive cost per unit

• Excellent flexibility after foaming

• Widely used in industrial filter applications such as circular winding and wire wrapping.

3020 Structural Assembly Hot Melt Adhesive: Multi-Material Bonding Expert

3020 is engineered for frame accessories and component integration, delivering reliable adhesion across diverse substrates including plastic, filter paper, nonwoven fabrics, and metals. Ideal for filter frame assembly and multi-component integration processes.

Core Advantages:

• Designed for structural assembly

• Compatible with plastic, filter paper, non-woven fabric, and metal multi-substrates

• Reliable bonding for complex assembly processes
