Conduction Cotton

Conduction Cotton

Common materials for conduction cotton typically include PA+PET blends, with PA accounting for 70% and PET 30%.  

Integrated polymer cotton belongs to a type of synthetic thermoplastic fiber material, featuring high-temperature resistance, corrosion resistance, and dimensional stability. It offers superior flavor reproduction, a soft mouthfeel, uniform density, high fluffiness, excellent elasticity, and minimal deformation.  

High oil absorption and retention: Tested at a density of 0.06 kg/m³, it can absorb over 120% oil capacity without leakage.  

Efficient oil release: Minimal residual oil (measured at ~11%), ensuring consistent vaping performance.

Product features:

1.The maximum diameter of circular storage cotton can be made up to 45mm. The minimum diameter of circular storage cotton can be achieved as small as 3.8mm.

2.Gradient Porosity, Even Distribution

3. The density of oil-conduction cotton can be adjusted as needed based on client requirements.

(Common density range: 0.05-0.08 KG/m³. A small number of clients may adjust the density according to the viscosity of e-liquid and taste preferences.)

4.Efficient Absorption, Enhanced Performance.

5.Leak-Proof & Clog-Free

6.Lightweight & Cost-Efficient

7.Irregularly shaped cotton can be customized according to the client's product design drawings.

Product Specifications & Customization

1. Precision Geometric Capabilities

   - Circular Dimensions: Maximum diameter **45mm** (for tank systems) to minimum **3.8mm** (for pod devices), maintaining ±0.1mm tolerance.  

   - Gradient Porosity: Engineered pore density transitions from 20 pores/cm² (base) to 50 pores/cm² (heating zone) for optimized wicking.  

2. Tailored Density Solutions  

   - Standard range: **0.05-0.08 kg/m³**, adjustable to match e-liquid viscosity (e.g., higher density for high-VG blends).  

   - Custom formulations available for niche applications (e.g., 0.09 kg/m³ for sub-ohm vaping).  

3. Advanced Manufacturing Processes  

   - Laser-cut edges (±0.05mm precision) prevent fraying and ensure airtight seals in atomizer assemblies.  

   - Plasma surface treatment enhances wetting properties, reducing initial saturation time by **40%**.  

4. Design Flexibility

   - Irregular Geometry Support: CNC-machined to match proprietary device contours, with lead times of 5-7 days for prototype samples.  

   - Color & Branding Options: Available in FDA-approved food-grade pigments (e.g., blue, black) for OEM differentiation.  

Key Performance Metrics  

- Leak Prevention: Passes -50kPa vacuum test (simulating high-altitude transport) with zero seepage.  

- Clog Resistance: Maintains 0.8-1.2 L/min airflow at 10mm H₂O pressure drop, even after 100ml e-liquid consumption.  

- Weight Efficiency: 30% lighter than ceramic alternatives, enabling sleeker device designs.  

- Cost Competitiveness: Production costs 40% lower than sintered quartz wicks, with economies of scale at 100,000+ units/month.  

This proprietary conduction cotton technology represents a breakthrough in vaping component engineering, combining material science innovation with precision manufacturing to deliver unmatched performance, customization, and cost efficiency.
