Is ABS plastic used in household food dryers for toxic purposes?
ABS is not affected by water, inorganic salts, alkali alcohols and hydrocarbon solvents and various acids. But it is soluble in ketones, aldehydes and chlorinated hydrocarbons. It can cause stress cracking by the erosion of glacial acetic acid and vegetable oil. No poison ABS theory, but as engineering plastics, in order to meet the use requirements will add additives, so often have high odor, this usually toxic or carcinogenic, if it is food grade ABS, you can view the SPI plastic packaging is not only face identification scheme, is not marked with the number 5, according to the SPI plastic identification scheme in 5, the plastic products can be reused after carefully cleaning, and only a microwave oven plastic. But even plastic products labeled non-toxic should not be used for too long. Because under normal circumstances, the plastic products can be divided into three stages, a pre release, because the plastic will often according to a special request to add some plastic additives in the processing of the project, such as common plasticizer, antioxidant and so on. These plastic additives will be released in the early stages of the process, so under normal circumstances, buy plastic products to go home often smell a certain odor, this is normal.
First, ABS is generally used as engineering plastic ABS, impact resistance, heat resistance, low temperature resistance, chemical resistance and excellent electrical properties, but also has the characteristics of easy processing, product size stability, good surface gloss, easy painting, coloring, can also be sprayed on the surface of gold, electroplating, welding, and hot pressing the two adhesive processing, widely used in industry machinery, automotive electrical and electronic instruments, textiles and construction, is a very widely used thermoplastic engineering plastics.
Two, the medium-term stability, release of these plastic additives smell is not endless, generally after a certain period of time, plastic products will be stabilized, and also began to smell the smell disappeared, the safety of this period of time when using plastic products. Three, late aging, life, many daily plastic products are life cycle, with a long time, it will begin aging, and plastic products that harmful substances will also be released.
