▏PVC Soft Transparent Pellet Granulation Production Line: Precision Manufacturing for High-Clarity Applications
Overview of the PVC Soft Transparent Pellet Granulation Production Line
The PVC Soft Transparent Pellet Granulation Production Line is a specialized industrial system engineered to produce ultra-clear, flexible PVC pellets for applications demanding exceptional optical clarity and elasticity. Integrating advanced extrusion, thermal stabilization, and precision cutting technologies, this line ensures consistent pellet quality, low yellowing index, and compliance with FDA/EU food-contact and medical-grade standards. Ideal for transparent packaging, medical tubing, and consumer goods, it combines process efficiency with rigorous material purity control.
Key Components and Process Flow
Co-Rotating Twin-Screw Extruder
Equipped with a 40:1 L/D ratio screw and 10-zone temperature control (80°C–160°C), the extruder gently processes PVC blends without degrading heat-sensitive additives (e.g., non-phthalate plasticizers). A vacuum degassing unit removes trapped air and volatiles, achieving ≤0.1% moisture content for crystal-clear pellet output.
Underwater Pelletizing System
The patented underwater cutter ensures smooth spherical pellets (1–4 mm diameter) with a surface gloss ≥90 GU. A closed-loop water temperature control (15°C±1°C) prevents thermal stress, while centrifugal drying achieves ≤0.05% residual moisture.
Technical Specifications and Performance Data
Output Range: 300–1,200 kg/h (adjustable screw speed 50–200 RPM)
Pellet Transparency: Light transmittance ≥92% (ASTM D1003)
Energy Efficiency: 0.18–0.28 kWh/kg (variable-frequency drives)
Control System: Allen-Bradley PLC with SCADA interface for recipe management
Safety: ATEX Zone 2 certification for explosive atmospheres
Competitive Advantages for Specialty PVC Production
Optical Clarity Optimization
A multi-stage filtration system (25μm mesh) eliminates impurities, while in-line UV stabilizers and anti-static agents are injected to maintain long-term transparency and dust-free pellets.
Flexible Formulation Compatibility
The line supports diverse PVC softener ratios (20–60 phr) and additives (e.g., impact modifiers, lubricants) without compromising pellet consistency. A quick-change screw design allows shiftovers within 45 minutes.
Target Applications and Industry Solutions
This production line caters to high-value sectors requiring premium soft transparent PVC pellets:
Medical Devices: USP Class VI-compliant pellets for IV tubing and respiratory masks
Food Packaging: FDA-approved pellets for cling films and transparent containers
Consumer Electronics: Anti-fog pellets for transparent device casings
Automotive: Weather-resistant pellets for interior trim lighting components
Quality Control and Smart Manufacturing Features
Real-Time Monitoring Systems
In-line spectrophotometers measure Yellowness Index (YI ≤2.0) and haze (≤3%), with AI-driven adjustments to extrusion parameters. Defective pellets are automatically rejected via pneumatic sorting gates.
Industry 4.0 Readiness
OPC-UA connectivity enables integration with MES for batch traceability. Predictive maintenance alerts (vibration/temperature sensors) reduce unplanned downtime by 70%.
Sustainability and Regulatory Compliance
The system features a closed-loop water recycling unit (90% reuse rate) and low-NOx burners, meeting ISO 14001 environmental standards. All contact parts use 316L stainless steel to prevent heavy metal contamination.
