Silicone Masterbatches: The Ultimate Plastic Enhancer
Silicone Masterbatches are concentrated pellets containing ultra-high molecular weight (UHMW) silicone dispersed in various plastic carriers. Instead of being a standalone material, they are "performance boosters" added to plastics during manufacturing to solve processing issues and improve the final product's quality.
● Concentrated Efficiency: High loading of silicone (up to 50%) in a convenient pellet form for easy dosing.
● Carrier Versatility: Available in different grades compatible with PP, PE, ABS, PC, Nylon (PA), and PET.
● Non-Migrating: Unlike liquid silicone oils, these masterbatches stay locked within the plastic matrix and won't "bleed" or "leak" to the surface.
● UHMW Technology: Uses ultra-high molecular weight silicone for long-lasting surface performance and durability.
● Invisible Improvement: Enhances properties without affecting the base plastic’s transparency or mechanical strength.
Key Features
● Better Scratch & Mar Resistance: Significantly reduces surface damage, keeping products looking brand new even with heavy use.
● Super-Smooth Processing: Acts as an internal lubricant, reducing friction during molding for faster cycle times and lower energy costs.
● Anti-Squeak Performance: Eliminates annoying "buzz, squeak, and rattle" (BSR) in automotive interiors and moving parts.
● Lower Coefficient of Friction (COF): Creates a "slippery" surface that improves the feel and functionality of moving plastic components.
● Perfect Mold Release: Prevents parts from sticking to the mold, reducing scrap rates and improving surface finish.
● Easier Handling: Unlike messy liquid additives, these dry pellets are clean, easy to store, and simple to mix.
