Azodicarbonamide Masterbatch
Azodicarbonamide Masterbatch
Azodicarbonamide masterbatch, with the primary active ingredient being azodicarbonamide (ADC), has a chemical formula of C2H4N4O2. It is a white or light yellow powder, non-toxic, odorless, non-flammable, and self-extinguishing.
The azodicarbonamide masterbatch is made by mixing azodicarbonamide with other carriers or additives and then processing it through special techniques into granulated products, making it easy to add and use uniformly in industrial production.
Azodicarbonamide has a high melting point, typically between 220~225°C (decomposes), and a density of about 1.65g/cm³. It is soluble in alkali but insoluble in gasoline, alcohol, benzene, pyridine, and water. When heated or subjected to pressure, azodicarbonamide decomposes to release nitrogen gas, making it an efficient blowing agent.

Environmentally Friendly Foaming Masterbatch
Environmentally Friendly Foaming Masterbatch
Eco-friendly foaming masterbatch is a type of plastic additive made by combining polyolefin materials with styrene-butadiene block copolymers as a carrier, along with auxiliary foaming agents.

Microspheres/ Expander
Microspheres/ Expander
Microsphere foaming agents are specialized foaming agents with a core-shell structure. The outer shell is typically composed of thermoplastic polymers, such as acrylic resin polymers, while the core contains low-boiling-point organic hydrocarbon gases.
When heated to a certain temperature, the shell softens, and the gas inside the core expands, causing the microspheres to rapidly increase in volume, achieving a foaming effect.

AC and NC Blowing Agents for Foam Plastics
AC and NC blowing agents are key raw materials for foam plastic production, yet their selection, dosage and process control directly affect foam density, elasticity and durability. This article details application parameters of AC blowing agents in EPS, EVA and other foam plastics (decomposition temperature 220-225℃, gas yield 200ml/100g), the principle of NC blowing agents enhancing foam anti-shrinkage, and provides a comparison of their selection, as well as solutions to common process problems (foam collapse, uneven bubbles). It helps foam plastic enterprises reduce costs, improve efficiency and produce high-quality products.
