PVC Transparent Thin Tube Production Solution
1. Formula Design
We use an optimized PVC transparent thin tube formula to ensure high clarity, excellent flexibility, and aging resistance. The basic formulation includes:
PVC Resin: High-purity SG-5 or SG-7 resin to ensure transparency and processing stability.
Plasticizer: Eco-friendly DOTP or DINP to enhance flexibility and reduce migration risk.
Stabilizer: Organotin or Ca/Zn stabilizers to ensure thermal stability and transparency.
Lubricant: Balanced internal/external lubricants to improve processing flow.
UV Inhibitor (optional): Enhances weather resistance for outdoor use.
2. Strict Raw Material Selection
PVC Resin: Test for volatile content (≤0.3%) and fish eyes to ensure purity.
Additives: Purity verified via chromatography to prevent transparency loss.
Colorants/Dyes (if needed): High-dispersion transparent masterbatch to avoid haze.
3. Mixing Process
High-Speed Hot Mixing: Temperature controlled at 110-120°C for even coating of PVC particles.
Cooling Mixing: Rapid cooling below 40°C to prevent agglomeration and maintain flowability.
4. Extrusion Pelletizing
Twin-screw extruder with low-temperature shear plastication (160-180°C) to minimize thermal degradation.
Die filtration (80-120 mesh) to remove impurities and ensure pellet purity.
5. PVC Thin Tube Forming
Extrusion Equipment: Precision single-screw extruder with a transparent专用 die.
Process Control:
Precise multi-zone temperature control (160-190°C).
Sizing sleeve and vacuum calibration ensure dimensional stability.
Online diameter gauge monitors tolerance (±0.1mm) in real time.
Product Advantages
High Clarity: Light transmittance ≥90% (1mm thickness).
Pressure Resistance: Passes 0.6MPa hydrostatic test (adjustable per requirements).
Eco-Compliance: Meets RoHS/REACH standards.
We provide end-to-end technical support from raw materials to finished products, with customizable formulas and specifications.
