There are many ways to make polyethylene in plastic water bottles. The most common one is to polymerize ethylene at a high temperature of 200-300 ° C and a pressure of 1000-2000 atmospheres. In polyethylene, it is not doped with other substances, so the polyethylene produced is low in density, soft in texture, and has high stability to sunlight, air, moisture and chemical agents, so no additional stabilizer or plasticizer is needed. . The plastic water bottle thus produced can be safe, convenient to carry, not afraid of falling, has acid and alkali resistance characteristics, and is also beneficial for recycling.
