Product Features

1. Adhesion Properties:

Initial peel strength: 90 g/in (±10%), providing fast and effective initial adhesion.

Adhesion time:>10 hours (standard test conditions) to ensure reliable fixation.

Final strength establishment: reached a steady state after 24 hours.

2. Physical Characteristics:

Substrate: 0.10mm cotton paper, flexible and easy to cut by hand.

Total thickness: 90±5μm (including release paper), with uniform specifications.

Tensile strength:>7 N/cm, the substrate itself has a certain strength.

3. Environmental Suitability:

Temperature range: 0℃ to 50℃, meeting most indoor environment requirements.

Storage stability: shelf life of 6 months in a cool and dry environment of 20℃-30℃.

Product Advantages

1. Operation efficiency: good initial adhesion, can quickly locate after pasting, reduce operation waiting time, improve production efficiency.

2. Material adaptability: has good adhesion to a variety of substrates (such as paper, plastic, leather), especially suitable for curved surface adhesion.

3. Cost-effectiveness: high production efficiency, good utilization of raw materials, help to control the overall cost.

Production and Processing Process

1. Preparation of rubber: EVA particles and additives are melted and mixed at a specific temperature (about 140-160℃) to form a uniform rubber solution.

2. Coating process: The 90u Hot Melt Double Sided Tape adhesive is evenly coated on both sides of the cotton paper substrate through precision coating equipment, and the thickness of the adhesive layer is controlled.

3. Composite process: the release paper is laminated on the coated adhesive layer, and the performance of the adhesive tape tends to be stable after cooling and maturation.

4. Post-processing: Cut and rewind according to order requirements, then package and store after passing inspection.

FAQ

1: What are the key differences between 90U, 80U, and 100U?

A: The key difference lies in viscosity: 90U strikes a balance between 80U (lower initial viscosity, easier adjustment) and 100U (higher initial viscosity, faster setting), making it ideal for general applications requiring immediate and reliable setting. When purchasing, choose based on specific requirements for initial viscosity and adjustment time.

Q2: Which surfaces are not bonded well by the product?

A: Oil, dust, damp surfaces, and low-surface-energy plastics such as PP and PE may affect the bonding effect. Ensure the bonding surface is clean and dry before use.

Q3: What should I pay attention to when storing?

A: The product should be stored in a cool and dry environment at 20℃-30℃, avoiding direct sunlight, high temperature or freezing. The recommended shelf life is six months.
