How to produce pearl cotton
Pearl cotton (EPE, Expandable Polyethylene) is a new type of environmentally friendly packaging material. Due to its lightweight, shockproof, heat insulation and other characteristics, it is widely used in electronic products, furniture, medical devices and other fields. The following are the production process and key data of pearl cotton, which are analyzed based on the environmental protection trends and technological innovations in hot topics in the past 10 days.
1. Pearl cotton production process
The production of pearl cotton is mainly divided into three core links: raw material preparation, foaming and molding, processing and cutting:
| Production process | Operation steps | Technical Highlights |
|---|---|---|
| Raw material preparation | Mix low-density polyethylene (LDPE) with foaming agent and additives | The ratio needs to be accurate, and the foaming agent accounts for about 3%-5% |
| Foaming molding | The material is expanded by heating and pressurization by extruder | Temperature control range: 120-150℃ |
| Processing and cutting | Slice, stamp or composite other materials as required | Thickness error needs ≤0.1mm |
2. Relevant analysis of hot topics
The "carbon neutrality" and "smart production" that have been hotly discussed on the Internet in the past 10 days have had a significant impact on the pearl cotton industry:
| Hot Topics | Industry impact | Data reference |
|---|---|---|
| Increase environmental protection policies | Promote the research and development of biodegradable pearl cotton | The number of new patents increased by 40% year-on-year in 2023 |
| Intelligent manufacturing upgrade | Increased penetration rate of automated production lines | Production efficiency of leading enterprises is increased by 25% |
3. Key technical parameters
The core performance indicators of pearl cotton directly affect their application scenarios. The following is a comparison of key parameters:
| Performance metrics | Ordinary pearl cotton | High-end antistatic pearl cotton |
|---|---|---|
| Density (kg/m³) | 20-30 | 25-35 |
| Recovery rate | ≥85% | ≥90% |
| Antistatic value (Ω) | 10^12-10^13 | 10^6-10^9 |
4. Market trends and innovation directions
According to recent e-commerce platform data, Pearl Cotton has increased significantly in the cold chain logistics and electronic product packaging fields:
1.Customized design: 3D molding technology can realize complex structure molding and adapt to packaging of special-shaped products.
2.Composite material: Pearl cotton composited with aluminum foil and non-woven fabric has become the new favorite of high-end packaging.
3.Recycling: The waste recycling and recycling cost is reduced by 30%, complying with the new EU regulations and standards.
