Order Great Silicone Masterbatch of Plastic Lubricant to Cut Torque and Boost Flow

Optimize your plastic processing with plastic lubricant: small-molecule agents like erucamide, oleamide, stearamide, behenamide, and PE wax provide immediate surface lubrication and low cost, while our high-molecular-weight silicone masterbatch offers superior permanence, non-migrating performance, and enhanced torque reduction. Unlike amide or wax additives that can bloom or wear off, the ultra-high-molecular-weight siloxane remains embedded within the polymer matrix, delivering consistent melt flow improvement, lower shear stress, and longer-lasting slip properties without surface residue. This synergistic approach ensures smoother extrusion, reduced energy consumption, and reliable, maintenance-free operation across films, profiles, and molded parts.

Identifying the Right Processing Aid

Engineer: "Our extrusion torque keeps spiking whenever we ramp up throughput. And the melt flow index isn’t where we need it.”
Purchasing Manager: “We’ve tried small-molecule plastic lubricant, but they migrate and cause uneven slip. What about silicone masterbatch?”
R&D Specialist: “There’s one that uses ultra-high-molecular-weight siloxane, pelletized via twin-screw extrusion, with SGS, RoHS, REACH, and PAHs certifications. It could be our best lubricant for plastic on plastic operations.”
Quality Director: “Does it really reduce torque by 20% or more and improve mold filling?”
R&D Specialist: “Independent data show 1.5% loading cuts torque over 20% and boosts line speed up to 30%—that’s faster extrusion speeds in pipes, profiles, and cables.”

This exchange illustrates the practical challenges in polymer processing—managing torque, ensuring uniform flow, and preventing lubricant migration—and sets the stage for why ordering a top-quality silicone masterbatch is a strategic move toward better productivity and product performance.

## Xiangxi Silicone Masterbatch: Material Selection and Production Process

Material Selection

• Ultra-High-Molecular-Weight Siloxane: We source a polysiloxane with molecular weights exceeding 1 million g/mol, ensuring it stays embedded in the polymer matrix rather than migrating out as low-molecular-weight oils do .

• Polymer-Compatible Carriers: Tailored LDPE, HDPE, PP, or TPU carriers optimize compatibility and dispersion, eliminating blooming and ensuring internal lubrication rather than surface-only slip .

• Halogen-Free, Non-Toxic Ingredients: All raw materials comply with SGS, RoHS, REACH, and PAHs environmental standards, guaranteeing safety for cable, film, and molding applications .

Production Process

• Automatic Dosing System: Gravimetric feeders meter precise amounts of siloxane and carrier resin, removing variability from manual weighing.

• Twin-Screw Extrusion and Pelletizing: High-shear twin-screw extruders melt-blend the formulation, followed by strand pelletization to produce uniform, free-flowing pellets that are easy to handle and feed.
  “One Test per Ton” Quality Control: At every stage—raw material inspection, in-process sampling, and final product testing—our lab conducts standardized tests (MFI, torque rheometry, COF, halogen analysis), ensuring each ton meets stringent specifications.

Key Features

1. Uniform Dispersion: Micro-dispersion of siloxane ensures consistent processing aid across the batch .

2. Environmental Safety: Certified under multiple global standards—SGS, RoHS, REACH, and PAHs—our masterbatch is halogen-free and non-toxic .

3. Pelletized Form: Free-flowing pellets simplify dosing in single/twin-screw extruders or injection molding machines.

## Benefits of Silicone Masterbatch: Reducing Torque and Enhancing Flow

Torque Reduction

• Quantified Performance: Adding just 1.5% of our masterbatch de silicone can reduce extruder torque by over 20%, translating to lower motor loads and prolonged equipment life.

• Energy Savings: Lowered torque demands reduce energy consumption by up to 15%, as reported in independent line-speed trials.

• Higher Throughput: With reduced mechanical resistance, line speeds can increase by 20–30%, boosting productivity without sacrificing quality.

• Melt Flow Index (MFI): Masterbatch loading improves MFI by 10–25%, enabling better mold filling and finer detail replication in injection molding .

• Die Buildup Reduction: Enhanced flow uniformity minimizes die drool in extrusion of films and cables, reducing downtime for die cleaning .

• Surface Slip and Release: A lower coefficient of friction simplifies part ejection and mold release, cutting cycle times in molding by up to 8%.

## Expert Insights: Trends, Opinions, and Real-World Cases

Industry Trends

• Shift to Functional Masterbatches: Demand for plastic lubricant that combine processing aids with functional performance (e.g., scratch resistance, low COF) is growing at 6% CAGR globally, driven by automotive and cable sectors.

• Sustainability Focus: Halogen-free and non-toxic additives align with circular-economy initiatives, spurring adoption in Europe and North America.

Expert Opinions

Dr. Maria Chen, Polymer Scientist, TechPolymers Inc.:
“Ultra-high-molecular-weight siloxanes offer a unique balance—enough migration to surface for slip, yet high molecular weight to prevent bleeding. When pelletized correctly, they outperform oils and lower-molecular-weight plastic lubricant in torque reduction and flow enhancement.” 

John Martinez, Extrusion Engineer, CableTech Solutions:
“In our HDPE microduct lines, switching to a pelletized siloxane masterbatch cut torque by 25% at 2% loading and raised line speeds by 30%. The ‘one test per ton’ QC protocol gave us confidence in batch-to-batch consistency.” 

Case Study: PE Film Extrusion

• Before: 0.5% liquid silicone oil, torque fluctuations up to ±15%, frequent die clean-outs.

• After: 0.5% silicone masterbatch, torque stable within ±3%, die drool reduced by 90%, scrap rate down from 4% to 1%.
