Product Name: Zinc p-toluenesulfinate
|Decomposition Temperature, ℃||250-255|
Packing: 40KG/Drum; 25KG/Bag
Zinc p-toluenesulfinate is a white fine powder with two molecules of internal Water of crystallization, insoluble in general solvents and water, with a melting point of more than 250 ℃, high photothermal stability, and non-toxic. FDA allows it to be used in food, medical and human contact packaging materials. Not classified as dangerous goods, without moisture absorption at room temperature, with stable chemical properties.
This product is an AC foaming agent foaming decomposition catalytic activator, suitable for all foaming agents, including ADC raw powder processing activation. The physical properties of the product are similar to those of the activator BM/ZBS, and the usage is also the same. Due to the high melting point of the product above 250 ℃, it can also be used as a PVC zinc salt stabilizer or as a high-temperature foaming agent (above 250 ℃) alone. The effect is similar to that of ZBS/BM active agent, which can completely promote the decomposition and foaming of AC foaming agent (100%) while improving the whiteness and glossiness of the product. It can significantly improve and reduce the usage of AC foaming agent (only with a utilization rate of 60-90% without using AC foaming agent). At the same time, it can greatly reduce the decomposition temperature of its AC foaming agent (or other foaming agents), activate and promote the decomposition rate of the foaming agent (100%) to fully decompose, and greatly increase the gas generation of the product (more than double). At the same time, it can absorb heat evenly to control the heat released from AC decomposition (release water vapor to absorb heat/promote the decomposition of the foaming agent), which is a feature that other zinc salts do not have (zinc oxide/basic Zinc carbonate), Add an amount of (AC foaming agent) of 3-20%. Widely used in all rubber and plastic foaming agents (such as AC/RA) foaming processes, it can also be used as a high-temperature foaming agent alone or as a PVC stabilizer.
It should be stored in a dry and ventilated place. This product is stable, non flammable, and flame retardant at room temperature.
