What Actually Happens Inside a Twin-Screw Extruder

This month, our new twin-screw extruder arrived at the plant. Installation, wiring, commissioning — the workshop has been a busy place. A colleague asked: what does a new extruder actually change? To answer that, it helps to go back to a single bla...

How does masterbatch produced ?

Have you ever thought about it? T he black granules that come out of your injection molding machine s , blown film machine s and pipe extrusion barrel, before being poured into your hopper, have gone through how many production processes? Today, let...

Why the Automotive Industry Demands High-Performance Masterbatch

A car interior is assembled from dozens of injection-molded parts - produced in different tools, plants and countries - that must match perfectly under showroom lighting and stay matched through sunlight and heat. That single sentence explains why automotive is one of the most demanding masterbatch applications, and why not every supplier can serve it.

How Jolink Black Masterbatch WM3F & WM3E meeting stringent requirements for water supply Pipe

Ensuring flawless raw material quality is the priority line of defense for guaranteeing the quality and safety of water supply pipes during construction. Jolink Masterbatch strictly adheres to both QB/T 4132-2010 and GB/T 13663 standards, meeting stringent requirements for water supply grades in everything from carbon black selection to additive systems. Using virgin tank/furnace process carbon black with a particle size ≤25nm, we ensure the carbon black forms a dense protective layer within the pipe, achieving highly efficient UV blocking and outdoor weather resistance and anti-aging properties. The carrier resin uses brand-new HDPE/LLDPE virgin raw materials, fundamentally guaranteeing melt compatibility with PE100 and PE80 pipe substrates and avoiding delamination defects. Based on this complete set of technical specifications, our water supply pipe-specific black masterbatch undergoes carbon black dispersion testing and moisture control before leaving the factory. This ensures that during actual processing, whether using single-screw or twin-screw extrusion, it can achieve synchronous plasticization with the substrate, effectively avoiding surface defects such as "sharkskin" or "crystal points" on the pipe surface. The actual addition ratio of our water supply pipe-specific black masterbatch can be stably controlled between 1% and 4%, resulting in not only uniform coloring, a bluish hue, high blackness, and high gloss, but also significantly improving the ring stiffness and long-term hydrostatic strength of the finished pipe, ensuring stable operation of your water supply network under harsh working conditions.
