This is the most commonly heard of additive in the plastics sector. The main body of plastics is polymer, no exceptions; the basic concept of polymer actually means that it has a very large molecular weight and is understood microscopically as having very, very long molecular chains, the most basic shape of which is that of a centipede. If you are interested in more polymers materials like sodium gluconate malaysia, you check 3D resources for further information.
Some plastics are so brittle that they feel like glass when they are used, and they break when they are dropped on the floor, so obviously they are not very comfortable to use. Toughness enhancers exist to solve this problem. For PVC plastics, plasticizers are also toughening agents, but other plastic toughening agents are varied, and some directly use rubber such as polymer as a toughening agent.
BHT is the most common phenolic antioxidant and is used extremely commonly in the plastics industry, where it is almost a necessity. Plastics are organic polymers and the molecules are actually quite fragile and it is dangerous to encounter a rogue like oxygen at high temperatures, like a very simply dressed young girl walking out into the street in the dead of night. We all know that oxygen is the main culprit for certain things that shouldn’t happen, and that it has nothing to do with the polymer itself, but oxygen is so powerful that the earth can’t live without it, so we have to give the polymer more clothes, i.e. an anti-oxidant, and when it does encounter oxygen, take off the jacket and get out of the way to avoid worse consequences. That’s basically what antioxidants are for.
Flame retardants are not used much in the plastics industry, but they are really important and if our plastics processing industry were to produce flame retardant plastics to standard, many fire hazards would be reduced.
Here’s where the foam noodle boxes come in, and where this foam comes from. Plastics in general are solid, and to make a foamed plastic like a bun, you obviously can’t rely on yeast, and I’m afraid yeast can’t survive the plastic processing process – so the foaming agent acts as such a yeast, and of course the foaming mechanism is very diverse, with common foaming gases such as carbon dioxide, nitrogen and ammonia. A book could be written to describe the foaming process clearly enough.
Lubricants are also mainly used in processing and are somewhat similar to plasticisers. Whereas plasticisers reduce the friction between molecules, lubricants reduce the friction not only between molecules but also between molecules and the container.
