The two test reports issued by Huating No. 2 Kindergarten in Songjiang District to parents are the testing of plastic granules and pavement materials. The inspections are respectively Shanghai Cailu Sports Field Materials Co., Ltd. and Shandong Jingyuan New Materials Technology Co., Ltd. the company. For the problem that the inorganic particles content exceeded the standard in the plastic particle test report, the reporter contacted Xie Mou, the contact person of Shanghai Cailu Sports Field Materials Co., Ltd. yesterday. However, he declined the interview of the reporter on the grounds that he was only a trader and he did not know the manufacturer. According to the public information of the Municipal Industry and Commerce Bureau, Xie Mou is the legal representative of Shanghai Cailu Sports Field Materials Co., Ltd., which mainly sells sports venue materials and plastic products. The reporter then contacted the inspection unit “Pavement Material Adhesive†– Shandong Jingyuan New Material Technology Co., Ltd. Tang Yuanjing, general manager of the company, explained that the products produced by the factory for laying kindergarten outdoor ground are called “safety mats†or “safety tiles†internationally. It is an environmentally-friendly recycled product, which is made up of waste tires, added with environmentally friendly adhesives, and heated and pressed. He bluntly said that at present, there is no safety standard for such products in China, and there is no chemical experiment in Europe. Only the physical resilience of products is tested. "Since 2001, our safe mat products have been exported to the UK, Belgium and other countries. So far no security issues have been found." After seeing the plastic floor laid by Huating No. 2 Kindergarten, Tang Yuanjing said: "This plastic floor is similar to the stadium track, not a special safety mat. The construction party may use our adhesive or it may not be used. Our product test report The kind of lipid (referred to as MDI) is normal. Without this kind of lipid glue, it can't be used." So, what exactly is MDI? According to online public information, the chemical meaning of MDI is diphenylmethane diisocyanate, which is a synthetic material that is toxic and irritating to the eyes and mucous membranes. The allowable concentration in air is 0.02E-6. Is the pungent odor emitted from the plastic runway the taste of MDI? Tang Yuanjing said: "It should not be the taste of MDI. The smell should be the softening oil in the rubber. It tastes like it is under the heat of the sun. It is just like the decoration. Like a house, it will be better after it has evaporated." So, what is the excess inorganic substance in the plastic particle test report? Tang Yuanjing speculated that inorganic matter generally refers to the filler in rubber particles: calcium carbonate.
