White Blowing Agent for TPR,PS

This series of foaming agents is used mainly in the foaming extrusion or injection of PVC,TPR and PS for making profile materials, plates or sheets and for making such low-foam plastic products as shutters and mirror frames, and PVC slippers and sandals formed by injection technology.CharacteristicsNo scale formed on the wormControllable foamingGood whiteness of products.Uniform cells.Smooth surface of products.Application specification:This series of foaming agents is a solid white powder liable to flow. The residue left after its decomposition is pure white and does not affect the color of products.This series of foaming agents possesses a good compatibility with PVC,TPR and PS so they may be dispersed evenly in the above molten resins while forming a system with uniform phases meantime this foaming agent contains bubble-hole regulator to make bubble holes in the foamed products become fine and even, which in turn helps to maintain an uniform performance in all parts of the product .This series of foaming agents is made of the adjutant of food grade, and gases generated after its decomposition are N2 and CO2 that wont corrode equipments of production and processing and wont do any harm to the human body, and therefore it is an environment-friendly productThis series of foaming agents is an endothermal foaming agent without need for induction term, the decomposition is completed stepwise and no eruptive decomposition ill happen, therefore bubbles in the molten resin will grow evenly and steadily and they wont break or overflow over the product surface to affect the product quality, which endows the product with an excellent trait-uniform bubbles and smooth surface.Technical index:Brand N-1000 N-2000 N-3000Chemical components Denatured carbonatesAppearanceWhite powder liable to flowDecomposing temperature() 160 180 140 160 150 170Amount of gas produced (ml/g)STP 140±5 140±5160±5Average granular size (μm) 68 68 68Moisture content (%) ≤0.3pH 8.08.5Package and storage:This series of foaming agents is free of odor and toxicity. Lt allows easy storage and transportation and it is self-quenching. Lt wont decompose under the common temperature, however, it 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 direct acids and alkalis, It is suggested that good ventilation conditions should be realized whore the foaming agent is treated or mixed, Be careful not to inhale its powder, not to make frequent skin contact with it and not to swallow it.A bag contains 25kg of this kind of foaming agent: bags are packed in cartons or barrels depending on clients demand. The total weight of the same batch, users may test only a handful of it for it for confirmation: if the test result is OK, then they may use the whole batch with certainty.
