blowing agent for pvc,
foam blowing agents
Yellow foaming agent HF640 is a special foaming agent for extrusion of rigid PVC low foaming wide sheet and profiles. The chemical composition is azodicarbonamide, the molecular formula is C2H4N4O2, also known as ADC foaming agent. HF640 is an endothermic and exothermic balanced foaming agent, which is more controllable and stable; the crust effect is lower than HF630, the hardness of crust layer can reach Shao's D55-65, and the foam is fine and uniform. For thick-walled products, there will be no discoloration in the middle layer, so pure white plastic foaming products can be made.
Compared with other AC foaming agents, the foaming agent HF640 has the disadvantages of low gas generation; the advantage is that the density of the product decreases linearly with the increase of the amount of foaming agent added. Other blowing agents will have an inflection point with the increase of the amount of addition, that is, when it is added upward, the density will become larger, resulting in a bad color of the product! Therefore, based on this advantage of the foaming agent, more foaming agent and calcium carbonate (15-30 PHR)can be added in the formulation , and the density can be kept to a relatively low level (0.4-0.5), the cost Can be very well reduced! Improve the competitiveness of enterprises! It can be combined with the mold to form a good surface crust effect.
