Material: Azodicarbonamide
Appearance: light yellow powder
Usage: artificial PVC leather in calendering and coating process

Product Introduction:

This series of foaming agents is developed based on the meticulous research of the technological characteristics of artificial leather. This series of foaming agents is suitable for different processing technologies of artificial PVC leather.

Characteristics:

Large gas volume

Rapid foam generation

Excellent rebound elasticity

Uniform cells

Strong feeling of natural leather

Application specification:

Compare with common AC blowing agents, this kind of blowing agents is characterized by more radical decomposition, less residue of the blowing agent, and greater amount of available gas produced. Its consumption reduces about 10% when used in foaming by release paper method, and over 5% in foaming by calendaring method. By using this blowing agent, the phenomenon troubling manufacturers-a yellow appears on the surface of white leather-will be eliminated, and the color of product made of the light-colored leather will become more genuine and brighter.

By using this series of foaming agents, the product will show such merits as uniform and fine cellular structure, comfortable feel, good rebound elasticity, and strong feeling of natural leather. The effect of artificial veins in the leatherette will be notably improved by using this foaming agent.

This series of foaming agents can match the different technology of leatherette processing, depending on the different decomposing temperature. AC3000F as an ultra-fine high-temperature foaming agent is suitable to the leatherette production by calendaring method, and it is characterized by rapid foam generation.

AC5000F and AC180F are suitable for the leatherette production by release paper method and to the production of semi-PU leatherette respectively. By using AC5000F and AC180F, the temperature of foaming oven can be reduced by 20-30°c without affecting foaming speed and quality, which enhances noticeably using intensity and frequency of release paper.

Package and storage:

AC series of foaming agents is free of odor and toxicity. It allows easy storage and with self-extinguishment. It won't decompose under the common temperature but should be kept in the shady, cool and dry place and be kept far from hot steam pipeline, fire source and direct sunlight. Never let it contact directly acids is stored or mixed. Be careful not to inhale its powder, make frequent shin contact or swallow it.

Each 25kg  is packed in plastic lined bag, carton or fiber drum according to clients' demands. While using this kind of agent, you may feel a little sticky. Don't worry about the quality. The sticky feeling is the normal trait of the foaming agent, it is not caused by moisture, and won't affect its use.

Each batch of this kind of agent weighs 3 tons. When using the foaming agent of same batch, only a handful is needed to test for confirmation, and then the whole batch can be used with certainty.
