PVC/TPR Field Used AC Blowing Agent

Product Introduction

This foaming agent is used mainly in   extruding foaming of PVC, TPR and PS for making pipes, plates, and section materials, and used in injection molding of them for making toys and other articles.

Characteristics

Self-formed nucleusi             Stable performance of final products

Controllable foaming             Uniform and fine cells

Application

This foaming agent features a good   compatibility with PVC and TPR, so they will disperse evenly in the molten   resins during processing to form a system with uniform phases, which in turn   helps to maintain a uniform performance in the product.

Endotherm-exothem balanced foaming agents   can balance the heat generated by AC decomposition to eliminate such problem   as unstable bubble holes and shrunken holes caused by the lower adhesiveness   of molten resin, so that bubble holes in the product becomes uniform and   dense.

The decomposing temperature of   endotherm-exothem balanced foaming agents falls in the range of temperature   for PVC processing, no induction term is needed for decomposition, the gas   release is even and without eruption, and nuclei will be formed by   themselves. These entire characteristics make the foaming process become more   controllable, which guarantees the stability of performance of the foamed   product of greater thickness and complex shape during the dynamic foaming   process.

Package and Storage

This foaming agent with excellent store stability   under the common temperature. But it should be kept in the cool and dry place   and far from hot steam pipeline, fire source and direct sunlight. Never let   it contact directly with acids and alkalis. It is suggested that good   ventilation conditions should be realized where the foaming agent is treated   and mixed. Be careful not to inhale its powder, make frequent skin contact or   swallow it.

A bag contains 25kg of this kind of foaming   agent and the bags are packed in cartons or barrels according to clients’   demand.

Each batch of this foaming agent series   weighs 3 Tons. While 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.
