[Chemical Knowledge]：What kind of plastic is PPT? Interpreting the story behind PPT

Read： 1350 Time：16months ago Source：Transform the World with Simplicity

In modern society, PPT has been widely used in all walks of life, and has become an indispensable part of social activities. However, we rarely pay attention to the secrets behind these seemingly ordinary slides.

In fact, the plastic used in PPT is polystyrene (PS), which is also a plastic material widely used in daily life. PS materials are usually provided to manufacturers in the form of granules, and various shapes of articles can be produced by heating and compressing.

Although the PS material has many advantages, such as low cost, good processability, and excellent visual effects, it also has some disadvantages, such as non-degradability, exhaust gas and waste water generated during the manufacturing process, etc. In addition, PS material is also considered to have a greater impact on the environment, so its use should be minimized.

In order to reduce the impact on the environment, some manufacturers have begun to try to use some more environmentally friendly materials to produce PPT. For example, some manufacturers use polylactic acid (PLA) material, which is a biodegradable material that can significantly reduce the environmental impact of PPT. At the same time, some manufacturers are also improving the production process of PS materials to reduce the generation of waste.

In addition to the selection of materials and the optimization of the manufacturing process, we can also reduce the impact of PPT on the environment through the rational use of PPT. For example, we can reduce the waste in the production process as much as possible, extend the service life of PPT as much as possible, or use digital tools to replace PPT.

Although PPT has become an indispensable part of daily life and work, we should always pay attention to the hidden stories behind it, and actively take measures to reduce its impact on the environment, and integrate environmental protection concepts into the production and use process.
