The full form of PLA in Science is Polylactic acid or polylactide. Now that you know the meaning of PLA, what is it exactly? PLA is a biodegradable and bioactive polyester that is formed with the help of lactic acid building blocks.
The high-density version of PLA was developed by using lactide and through the scientific process of ring-opening polymerization. It was discovered by Wallace Carothers in 1932 while heating lactic acid under a vacuum through removing condensed water.
Polylactic acid is a thermoplastic monomer which is derived from renewable, organic or natural sources such as corn starch. The production of PLA is pretty cost-effective.
Applications of PLA
As we mentioned earlier, PLA is biodegradable which makes it suitable for fashioning plastic film, bottles, and biodegradable medical devices, including screws, pins, plates, and rods.
It is also useful in packaging items with shrink-wrap as it melts pretty well and can be used for 3D printing. So, it is cost effective, and can be used in many ways that can save up more of your money.
Frequently Asked Questions on Full Form of PLA
. Is PLA biodegradable?
Yes, PLA is biodegradable to a great extent. There are various methods through which you can decompose hydrolysis, thermal degradation, or photodegradation.
. What is PLA made of?
PLA is made from fermented plant starch from corn, cassava, maize, sugarcane, or sugar beet pulp.
. Where can PLA be used?
Polylactic acid can be used for 3D printing, shrink-wrapping, nails, bolts, rods, etc.
. What are the disadvantages of PLA?
PLA melts at very low heat, is not very reliable when it comes to strength, and is sometimes difficult to handle.
