Is Plastic Strong Enough?

People often make the assumption that metal is the strongest building material on the market, but that is a common misnomer.  In many instances plastics can actually be stronger than a lot of metals, and even have a longer lifespan.  Plastic manufactures work on developing stronger variations of plastics that can be used in a multitude of industries and come customizable options.

When compared with die cast metals, plastics are as strong and durable, but also have better performance, weight, costs, and manufacturability.  Plastics also have a lower environmental impact than most metals. Most importantly, plastic has the amazing ability to be designed in so many different shapes and sizes.

Plastic can be assembled in so many different designs, and can withstand a great deal of damage. An example of plastic’s strength is seen in the protective case sector.  It is common to find protective cases made out of plastic, instead of metal. There are many companies that make custom molded plastic cases to protect important goods.  Blow molding is a popular technique used in the plastic manufacturing sector.  The process inflates soft, molten plastic into a desired shape. Blow molded cases can protect a wide range of fragile goods from any different elements. They can protect guns, medical equipment, and fragile items from hard falls. Also, cases can be designed to shield materials from all types of elements ranging from heat, water, or even frigid temperatures.  These custom carrying cases are the best way to protect important goods while traveling. For instance, if you are traveling with a camera, it is wise to pack it in a custom carrying case made out of strong plastic.

Looking at yield strength is the best way to determine which stronger: plastic or metal.  The yield strength is the amount of stress a material can withstand before showing permanent deformation.   Plastics are more sensitive than metals, and have less predictability, meaning that there are many factors that need to be taken into account when trying to quantify strength.

When properly manufactured, plastic products are strong and durable, and have a ton of performance benefits. If you are looking into purchasing a specific plastic, and want to know it’s strength, it is always best to contact a local professional in the field of plastic manufacturing.  Professionals make their livelihood out of manufacturing different plastic strengths. They are by far, the most well versed experts on plastic strength and durability.
