1. Substrate Structure Characteristics
The paper substrate is 0.12mm thick. It has a tensile strength of 85N/cm (longitudinal) and 78N/cm (transverse). The strength difference between directions is within 8%. This reduces deformation from uneven stretch. The substrate stays intact at 150°C. It performs better than standard cotton paper in heat resistance.
2. Adhesion Performance
Peel strength on PP/PE reaches 8N/25mm. This is about 40% higher than standard Crown DS512 Double-sided Tapes. Initial tack (12# steel ball) and holding power (>48 hours with 1kg load) meet industry norms. The adhesive is designed to bond well on curved surfaces and sharp edges.
3. Production Process Adaptation
Peel force is 5–10 N/25mm. This fits most automatic mounting machines. The Crown DS512 Double-sided Tape can be slit at speeds up to 300m/min. It supports fast processing. The minimum cutting diameter is 2mm. It works for small and precise parts.
4. Quality stability Assurance
After 240 hours at 85℃ and 85% humidity, adhesion stays above 90% of original strength. The coating process keeps adhesive thickness within ±0.005mm. The production area meets Class 10, 000 cleanroom standards. This ensures a clean, stable product.
5. Benefit Analysis
The ultra-thin design saves space. It fits tight areas. After 500 hours of UV aging, it keeps its physical properties. It meets VOC standards for car interiors. It is eco-friendly and compliant.
1. Substrate Pretreatment Process
Paperboard substrate inspection: Tensile strength test (≥85N/cm in longitudinal direction, ≥78N/cm in transverse direction)
Plasma treatment: The substrate surface tension is elevated to 50-52 dyn/cm through corona treatment equipment
Preheating and setting: The substrate undergoes stabilization treatment on a 80℃ preheating roller to eliminate internal stresses.
2. Adhesive Preparation System
Raw material ratio: Acrylic monomer and tackifier resin are pre-mixed in a 7:3 ratio.
Reactor synthesis: Conduct a 6-hour polymerization reaction at a constant temperature of 85℃
Viscosity adjustment: Use a rotational viscometer to control the adhesive's viscosity within the range of 3500±500 cps.
3. Precision Coating Process
Double-sided coating: Utilizes a micro-embossed coating head with a speed of 15-25m/min
Coating control: Both sides have a thickness of 0.06mm, with a total thickness of 0.12±0.02mm
Drying system: Three-stage oven with temperature settings of 60℃/80℃/100℃ respectively
4. Composite Machining Process
Release film lamination: Composite with silicone oil release film (release force 5-8g/in) and adhesive tape
Maturation: The cross-linking reaction is completed by leaving the material in a 40℃ constant temperature maturation chamber for 48 hours.
Quality control: The online monitoring system tracks coating uniformity in real time (tolerance ±3%)
5. Post-Processing Flow
Slicing process: Utilizes a circular blade slicer with precision of ±0.2mm
Reel control: Constant tension rewinding (Tension range 2-5N)
Packaging conditions: Packaging completed at 23±2℃ temperature and 50±5%RH humidity.
6. Key Points of Quality Control
Each product roll undergoes initial adhesion (12# steel ball) and adhesion retention (>48h) testing.
Each batch undergoes temperature resistance testing through cyclic cycles (-20℃ to 80℃).
Conduct regular SGS testing on samples to ensure compliance with RoHS standards.
