Why the aging, active population is favoring joint preservation over traditional total joint replacement. Extremely high melting point. Plastics now offer similar tensile strengths of metal, can be thermally conductive, resistant to heat and chemicals, and offer many other properties once thought of to be unique to metals. Moreover, they have enough strength and stiffness to replace metals in many applications. 148 views Compared to precision metal gears, lower investment for mass production owing to injection-molding production process; No need for secondary machining, hardening or finishing operations; Possibility of hybrid technology with composites, metals and other plastics Some of the key benefits of replacing metals with polymers include: Weight reductions of … But for elastomers, this property can be an advantage for come applications. There are various advantages of conducting polymers over metals, which is why metals are being constantly replaced by conducting polymers: Lighter in weight. Composites in structural applications have the following characteristics: 1.3 Advantages and Disadvantages of Composites Composite parts have both advantages and disadvantages when compared to the metal parts they are being used to replace. Resilience – the ability to deform and spring back to their original shape without major damage. The word “plastic” means pliable, or a material that can easily be shaped. While metals generally have a long life span, they are highly prone to chemical and weather attacks which reduces their overall life span.Â, Plastics, on the other hand, are considered more resistant and have a longer lifespan in comparison.Â. These materials consist of a polymer matrix reinforced with fibers (typically glass, basalt, carbon or aramid). 6) But not the same ring that polymer … If we take a ball made of a polymer material such as plastic and a ball made of a metal with the same size, we can observe that the metal ball is heavier than the plastic ball. Copyright © 2020 Rodman Media. Polymer and composite materials such as PEEK, kynar, Teflon, and polyethylene are impervious to some of the harshest chemicals. Therefore, this property of the polymer is highly advantageous because we can replace metal with … Properties like lightweight, durability, thermal conductivity, faster manufacturing, etc are some key advantages of using plastics over metals.Â, With the invention of new polymers, plastics are fast replacing their metal counterparts in multiple industries like automobiles, medical care, agriculture, aerospace, and hospitality.Â, While environmental concerns over plastic disposal can not be ignored, planned use of plastics (along with focused efforts on recycling and reuse) in multiple industries has various advantages to offer in the coming years.Â.
