POM/PBT Engineering Plastics Modifying Twin Screw Extruder

1. Product Overview

Polyoxymethylene (POM) and Polybutylene Terephthalate (PBT) are highly crystalline engineering plastics known for their incredible friction resistance. However, POM is extremely sensitive to shear and can easily decompose into formaldehyde gas if overheated. This specialized Modifying Twin Screw Extruder is engineered with a strict low-shear profile and exceptional cooling capabilities, providing a safe, stable, and highly efficient compounding environment for sensitive crystalline polymers.

2. Core Advantages

• Thermal Degradation Prevention System: Specifically calibrated low-shear screw elements combined with localized PID micro-cooling prevent thermal spikes and protect temperature-sensitive POM polymer backbones.
• Multi-Stage High-Vacuum Venting: Features stacked multi-port vacuum extraction channels designed to safely remove trace formaldehyde gas and volatile organic compounds (VOCs) instantly.
• Gravimetric Material Dosing: Utilizes loss-in-weight gravimetric feeders to deliver precise stoichiometry for heat-sensitive additives and specialized friction modifiers.
• Rapid Thermal Dissipation: Custom internal barrel water jackets deliver enhanced thermal conduction speed, ensuring tight melt-temperature thresholds during continuous runs.
• Gentle Homogenization: Deep-flighted screw design minimizes frictional shear heat while maintaining superior distributive mixing for additives like PTFE or silicone.

FAQ

Q1. How do you prevent POM from degrading and emitting gases?

A: We configure a specific low-shear screw profile to minimize frictional heat and utilize an ultra-precise PID cooling system to keep the melt strictly within its processing temperature window.

Q2. How do you ship the goods and how long does it take to arrive?

A: Ship by sea for heavy machinery. Depending on the destination, it takes 15-35 days to arrive.

Q3. Is it OK to print my logo on the machine?

A: Yes. Please inform us formally before our production.
