Innovative applications and solutions of hot melt adhesives in the electronics field

Application Adhesive for Electronics

Core application scenarios of hot melt adhesive

With the trend of precision and miniaturization of electronic products,
hot melt adhesives have transformed from traditional packaging fields to key auxiliary materials in electronic manufacturing.

Consumer ElectronicsUltra-thin bonding (adhesive layer <0.1mm)Foldable screen phones, TWS earbuds
Automotive ElectronicsTemperature resistance from -40℃ to 150℃In-car central control screens, BMS battery management systems
Industrial EquipmentIP67-rated sealing and protection5G base stations, industrial sensors

Screen fit

Our hot-melt adhesive has overcome three major technical bottlenecks in flexible screen mass production processes:

Bubble-free Control: When vacuum bonded at 0.5MPa pressure, bubble diameter <50μm

Curvature Adaptability: Withstands over 100,000 dynamic flex tests (R=3mm)

Yellowing Inhibition: ΔYI<1.5 under 3000lux UV irradiation (CIE LAB standard)

Thickness100-200μm25-75μm
Curing MethodMoisture-cured
Repair DifficultyIrreversibleSeparable by heating to 80℃

Battery Packaging

In lithium battery thermal runaway accidents, 23% are caused by packaging failures. Our hot-melt adhesive offers excellent sealing and can withstand temperatures up to 140℃.

TypeInitial Adhesion(N/cm²)Application Scenario
EVA Adhesive5.2<3%/1000h
PUR Adhesive8.7<1%/1000h

PCB component fixing

In 5G millimeter wave devices, our hot melt adhesive meets the following requirements:
High frequency adaptability: dielectric constant Dk<3.2@10GHz, loss factor Df<0.02
Miniaturization processing: dispensing line width 0.2mm, adaptable to 01005 package components
Thermal management synergy: adding 30% boron nitride filler, optimizing thermal path

Adhesive (Shanghai) Co.Ltd

Choosing us is not only choosing a high-performance hot melt adhesive, but also choosing a reliable and professional partner.
