PET color multifunctional masterbatch

PET color multifunctional masterbatch product

——Highly dispersed, highly stable, environmentally friendly PET special colorant

Product introduction

This PET color masterbatch is a high-performance colorant specially developed for polyethylene terephthalate (PET) plastic products. It is suitable for various PET processing technologies such as bottle blowing, injection molding, sheets, and fibers. The product is refined with high-purity carrier resin, high-quality pigments and functional additives. It has excellent dispersibility, thermal stability and color consistency, and can be widely used in food packaging, beverage bottles, cosmetic bottles, textile fibers and other fields.

Product advantages

1. Excellent color performance

Provide a variety of standard colors (transparent, translucent, solid color), and can customize special colors

High tinting strength, low addition amount (1%~3%) can achieve the ideal color effect

Uniform and stable color, no streaks, color difference problems

2. Excellent processing performance

High temperature resistance: can withstand PET processing temperature (270~300℃), no decomposition, no discoloration

Excellent dispersibility: Nano-level grinding process to avoid pigment agglomeration, ensure smooth surface of the product without crystal points

Low volatile matter: strictly control moisture and low molecular volatiles to prevent bubbles, silver streaks and other problems

3. Safety and environmental protection

Comply with FDA, EU 10/2011, GB 4806 and other food contact material regulations

Does not contain heavy metals (Pb, Cd, Hg, etc.) and harmful organic compounds (PAHs)

Some color systems can provide biodegradable compatible formulas to help green packaging

4. Diversified functions

UV-resistant type: contains ultraviolet absorbers to extend the service life of outdoor products

High barrier type: suitable for beverage and drug packaging that need to be stored away from light

Special for laser marking: optimize laser absorption rate and improve marking clarity
