Today, many things in life are made of plastic, and the plastics are also easy to use. These plastics are divided into many categories, and these plastic materials provide us with a lot of things in life. convenient. But this material of plastic is inherently toxic, no matter which kind of plastic is like this. So let's take a look at the knowledge about plastics. Is it true that pe plastic is poisonous? Let's take a look.
What is plastic?
Plastics are macromolecular compounds (macromolecules) which are polymerized by addition polymerization or polycondensation reaction. They are called plastics or resins. They can be freely changed in composition and shape, from synthetic resins and fillers. It is composed of additives such as plasticizers, stabilizers, lubricants and colorants.
The main component of plastic is resin. The term resin is first named by the lipids secreted by plants and animals, such as rosin, shellac, etc. Resin refers to a polymer compound that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with or without additives, such as plexiglass, polystyrene, and the like.
Is pe plastic toxic?
Pe is a shorthand for English polyethlene, a thermoplastic resin obtained by polymerizing ethylene. It has excellent low temperature resistance, corrosion resistance, excellent insulation, water absorption, normal solvent at room temperature, good chemical stability and the like. It has a big role in our lives, so what kind of approach is this material generally used for?
To say that plastic is basically toxic, don't eat plastic. But many plastics, such as plastic cups, and so on. It is necessary to reach a certain level of temperature to be toxic. The same is true for pe (polyethylene) plastic. The decomposition temperature of pe plastic is above 380 degrees. Therefore, it is still possible to use a cup basin made of pe (polyethylene) plastic, etc., and there is no fear of plastic poisoning.
In fact, to be precise, the plastic we usually use is not a pure substance, it is made up of many materials. In fact, not only pe plastics, but also a lot of plastics. It is necessary to reach a certain temperature to be harmful to the human body. Generally, as long as it is not the manufacturer's falsification, the plastic products we use are all insured and have no side effects on the human body.
