Extruder parts Screw Segment barrel and liner for Plastic resin mixing, compounding and granulation with halogen-free flame retardant

Product Description

Extruder Screw Segment, Barrel and Liner for Halogen-Free Flame Retardant Plastic Processing

Specialized extruder components designed for plastic resin mixing, compounding and granulation with halogen-free flame retardant (HFFR) materials. These high-wear parts are engineered to withstand extreme abrasion while ensuring efficient mixing and temperature control.

For HFFR compounding, extruder components must be constructed from highly wear-resistant materials (like bi-metallic alloys or Tungsten Carbide coatings) to withstand abrasion from mineral flame retardants. Their design focuses on efficient mixing and gentle heat control to achieve uniform compounds while maintaining polymer integrity.

Key Components

1. Screw Elements

Function: Core components mounted on screw shafts that convey, melt, mix, and pump plastic material.

Key Features for HFFR:

Material: Wear-resistant alloys (bi-metallic) to withstand abrasive mineral fillers like magnesium hydroxide (MDH) or aluminum hydroxide (ATH)
Surface Treatment: Tungsten Carbide (WC) coatings or hardening techniques (e.g., nitriding) to extend service life
Design: Special mixing elements (kneading blocks, mixing pins) ensure homogeneous dispersion of flame retardants without resin degradation

2. Barrel

Function: Houses rotating screws and forms the chamber for plasticization and mixing under high temperature/pressure.

Key Features for HFFR:

Liner/Bushing: Removable inner surface component that directly contacts material and bears wear
Material: Bi-metallic construction with wear-resistant alloy inner liner (e.g., Xaloy, Reiloy)
Cooling: Efficient cooling channels manage heat from shear stresses and filler friction

3. Liners/Bushings

Function: Replaceable inner sleeves that protect the main barrel body from wear.

Key Features for HFFR:

Designed as the primary wear component
Constructed from the hardest available materials (bi-metallic alloys or Tungsten Carbide coatings)
Replaceable design provides cost-effective maintenance for abrasive material processing
