Polymers are widely used materials that are used as raw materials in various industries. Compounds are special combinations of polymer materials that are obtained from the combination of polymer bases and other materials and will increase the durability and resistance of the final product. The most important advantage of using polymer compounds will be to increase the efficiency of the product and on the other hand reduce the weight of the final product. Compound 3840 is introduced as an example of compounds that is included in the group of polyethylene compounds. This material, like other compounds, will have the feature of increasing the efficiency of the product.<\/p>\n
<\/p>\n
In general, all types of polymer compounds are placed in two groups of polypropylene and polyethylene compounds. An example of polyethylene compounds is heavy polyethylene compound 3840. Polyethylene materials are divided into three groups based on density: light, linear and heavy. This type of grade is one of the rotating polyethylene grades and is considered a part of the rotational molding grade, and its exact name is HD3840UA. Heavy grades of polyethylene have a higher density than other grades of polyethylene. This type of compound has high and good processability.
\nThis compound will be created from the polymerization of polyethylene and due to having a series of properties, it is necessary to keep it in proper conditions. In this way, care should be taken to keep it in a place with proper ventilation, away from heat, sparks and flammable substances. It should be noted that although polyethylene in its solid and pure state does not affect the skin, if it comes into contact with dust or vapors from this substance, there is a possibility of irritation and watery eyes.<\/p>\n
The molding process with heavy polyethylene 3840 is circular. In this method, a certain amount of special plastic will be poured into the mold in the form of powder. This mold rotates at the same time during heating so that the powder slowly melts and sticks to the mold wall.
\nThen we take the mold out of the oven and it cools while rotating. In this way, the plastic inside the mold that sticks to the wall and creates a layer on the surface of the mold cools down slowly. Finally, the product can be removed from the mold while keeping the shape.
\nFeatures of compound 3840
\nThe most important features of Compound 3840 are its transparency and colorlessness, good internal and external surface finish, good impact strength, UV resistance, low cost, easy processability, and good resistance to cracking. Another major feature of this compound is its thermoplasticity, which has led to the use of this polymer in a wide range of applications.<\/p>\n
This type of compound is used for various applications according to its characteristics. It can be said that due to its good resistance to environmental pressures and cracking, ultraviolet rays and impact, it is a suitable grade for rotational molding used in the production of containers or water tanks. Among its other uses, the following can be mentioned.<\/p>\n

\nPurchase of compound 3840<\/p>\n
3840 heavy polyethylene produced in each of the petrochemicals may have differences in terms of some properties. Therefore, it is better to familiarize yourself with the best brands before buying and after consulting with sales experts, make a safe and quality purchase.
\nThe price of Compound 3840, like other polyethylene materials, is determined according to the conditions of the world market and the exchange rate. Other factors affecting the price are transportation costs and packaging production methods. However, in order to know the daily price of this compound, you can contact the sales experts of different production sets.<\/p>\n","protected":false},"excerpt":{"rendered":"
