DDP Diamond Dotted Paper Supplier | Custom & Bulk Orders Available

In modern electronic manufacturing, precision packaging, and industrial automation, the dispensing process is a critical step that directly affects product performance and reliability. DDP diamond dotted paper, with its precise dot positioning, strong adhesion, and environmentally friendly material properties, has become a commonly used material in electronics, electrical machinery, and semiconductor manufacturing. As a professional DDP diamond dotted paper supplier, we provide customized specifications and bulk ordering services to meet the specific requirements of different customers.

What Is DDP Diamond Dotted Paper?

DDP diamond dotted paper is a type of adhesive tape with a diamond-shaped dot pattern on its surface. This grid structure allows the adhesive to be evenly distributed on the target surface. Compared with traditional coating methods, DDP diamond dotted paper offers the following advantages:

High Dispensing Accuracy: The diamond grid design ensures uniform adhesive volume and reduces adhesive waste.

Strong Adhesion: This feature ensures that the adhesive bonds firmly, preventing slipping or sagging.

Environmentally Friendly Material: DDP tape is made from safe, low-pollution raw materials, making it suitable for industries such as electronics and medical devices.

Main Features of DDP Diamond Dotted Paper

1. Diamond Grid Structure

Precise Adhesive Control: The three-dimensional grid structure accurately controls adhesive thickness and distribution.

Uniform Bonding: The continuous diamond layout enables full-surface and even adhesion.

Good Flexibility: The structural arrangement enhances material flexibility, allowing adaptation to complex surface bonding.

2. Manufacturing Process

Adjustable Release Force: Supports customized differential release force on both sides.

Stable Lamination: The base material and functional layers are firmly bonded, ensuring long-term performance.

Consistent Thickness: Advanced production technology ensures uniform thickness for every batch.

3. Functional Characteristics

Adhesive strength can automatically adjust according to ambient temperature.

Built-in visual indicators facilitate alignment accuracy checks and quality control.

Application Fields of DDP Diamond Dotted Paper

Oil-Immersed Power Transformers

DDP diamond dotted paper is used as turn-to-turn and layer-to-layer insulation for coil conductors. During the drying and curing process, the adhesive melts and bonds, improving the mechanical strength of the coils, optimizing oil impregnation and gas release, and reducing the risk of corona and partial discharge.

High-Voltage Motors and Electrical Equipment

DDP diamond dotted paper is applied in anti-corona applications, enhancing the corona resistance of insulation structures in high-voltage motors.

Cable Shielding and Insulation Layers

DDP diamond dotted paper serves as an internal cable insulation and separation material, providing both electrical insulation and shielding functions.

Instrument Transformers and Amorphous Alloy Transformers

DDP diamond dotted paper is used for coil and interlayer insulation, improving the voltage withstand capability and short-circuit resistance of the equipment.
