It is produced at high pressure (1000-3000 bar; 80-300°C) via free radical polymerization process. Advantages and Disadvantages of Plastic . 2Advantages of plastic are light in weight. Low density polyethylene has less stiffness than the high density type. It is not nearly as puncture resistant either. LDPE is typically soft and flexible, yet it has good impact resistance, especially at low temperatures. Linear Low-Density Polyethylene (LLDPE) is very similar to LDPE, but offers added advantages. Disadvantages of polyethylene foam. Size: Sizing options for PVC pipes are limited, which can be an issue at times. Although it is typically used for bags and films, LDPE could be the perfect choice for your custom packaging. Advantages and Disadvantages of Blow Molding. This is because, like most plastics, heat can cause the material to warp and melt. Having widespread applications from industries to minute household stuff, its utility cannot be expressed in a few sentences. The following table examines this in more detail: Table 4. More Articles. Low Density Polyethylene (LDPE) is the most common type of plastic sheeting. Hence, due to such properties and durability, LDPE has wide variety of applications (High Density vs Low Density Polyethylene, 2017). Advantages Has higher tensile strength than LDPE. Compared to HDPE, it has a higher degree of short and long side-chain branching. What are advantages and disadvantages of… ADVANTAGES 1. This is due to the sole fact that plastic is non-biodegradable. The Advantages of Plastics in Automotives. Wire and cable insulations. Exhibits higher impact and puncture resistance than LDPE. LDPE Plastic. Cons LDPE can often suffer from stress-cracking and is flammable. Updated On: December 11, 2018. Glass reinforcement improves its thermal expansion, strength, rigidity and temperature resistance. … It is a well-known simple polymer with advantages and disadvantages for use in piping. Advantages: Has higher tensile strength than LDPE. Advantages and disadvantages of the material. By: Shelley Frost. Smash into a rock jetty, much less a piling, and a poly boat will just bounce right off. as well. LDPE also has very low conductivity which makes it useful as an electrical insulator. Other common plastics such as polystyrene, nylon and PET are three to 10 times as expensive. Copyright 2021 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. 2LDPE is well known for its flexibility and is used in plastics bags. Strengths & Limitations Applications Properties Processing Ethylene Vinyl Acetate . Blow molding like other forms of plastic molding, has its own advantages and disadvantages. High density materials are the most rigid. It has good or excellent resistance to acids and bases as well as many typical solvent types, including alcohols, aldehydes and esters. In a nutshell, here are the major advantages and disadvantages of polyethylene as opposed to fiberglass or aluminum: ADVANTAGE: Polyethylene is extremely impact-resistant, and we’ll go as far as to say that poly boats are virtually indestructible in the normal course of recreational boating. Although most people might not be aware of the existence of high density polythene, that doesn't mean they don't derive benefits from this versatile material. Rotational Molding - Working Principle , Application , Advantages, Disadvantages Rotational Molding The rotational molding is a high temperature and low LDPE has high ductility but low tensile strength, which is evident in the real world by its propensity to stretch when strained. Polypropylene is commonly used in the packaging industry, and in this article, we are looking at the advantages and disadvantages of the material. LDPE vs HDPE: Properties Production and Applications - Matmatch . ♦ LDPE offers less resistance to weather conditions. As with any foam solution, there are advantages and disadvantages of polyethylene foam. It has a density of 0.910-0.925 g/cm 3. We have listed some of the most common ones in this article.
