We are curious about whether the lunch box can put into the microwave?
1.The answer is best not to, because generally ABS is easy to get FDA certification, that is, direct contact with food is no problem, but for German standards, there is currently no product that can directly meet the standards. In addition, ABS has more or less residual acrylonitrile monomer, which will cause a trace of decomposition and the original monomer to escape after heating, which is highly toxic. So the plate is okay, heating is still cautious.
2.If the plastic is heated to the heat distortion temperature of ABS, the ABS product will deform even higher and may produce harmful gases.
3.At present, there are PP plastic products that can be heated in the microwave oven. The principle of the microwave oven is that the PP product itself does not catch the temperature it produces, and PEI can also be used. However, the cost of PES PEI is relatively high, and it is best to use PP products to warm up.
4.In theory, it is possible, but the melting temperature of ABS plastic is 217~237℃. If there is more oil in the lunch box, it will cause thermal runaway, that is, the plastic will melt in some places. Although this plastic is not toxic, it is good for food.
5. The only plastic that can enter the microwave oven is PP products (the recyclable number at the bottom of the product is <5>). The correct use temperature of ABS is -25℃~80℃, and the theoretical heat distortion temperature is 93℃
6. ABS plastic is a copolymer of acrylonitrile (A), butadiene (B) and styrene (S). Its disadvantages are flammability, low heat distortion temperature, poor weather resistance, and opacity. Commonly used in machine parts, various instrument casings, equipment linings, etc. It is recommended not to microwave heating.
