“Clear Plastic Face Shields” is not an invention. These plastic face shields were invented by a firm in New Zealand who developed them for the military, firstly in the 1970’s.
In my opinion, these shields don’t fall into the category of a new invention. The principles behind them are already well known and have been used for many years. That said, if you were to list the ingredients of face shields – to create a new product you would find silicone, polyurethane, resin, and polyester amongst other things.
So how does Clear Plastic Face Shields really work? These are simple designs that are manufactured using a plastic sheet and a flexible acrylic polymer that will expand as it cools.
As it expands, the first layer of the shield slips off onto the top layer which moves off to the side as it expands and the second layer pops out at the other side. It’s a very simple idea and an easy one to reproduce.
Plastic face shields are easy to make using silicone based rubber seals and can be made to fit a range of surfaces. There are plenty of websites on the internet which offer various designs and can even make them to order for you.
In fact, you can even make your own design using your own imagination. However, as with most things, you should be aware that there are variations of the product so there may be differences between the different products.
It’s also important to remember that the Clear Plastic Face Shields will not protect your face completely, as they are still open to air when they are cooling and so will allow moisture to enter the inner layers. This will slow down the cooling process and give a greater chance of you becoming dehydrated.
You need to make sure you wear protective clothing and cover up all exposed skin to avoid being drenched by your Clear Plastic Face Shields, as this is what can happen if you are dehydrated. The end result is similar but much quicker.
If you are not going to use your Clear Plastic Face Shields all the time then you are better off wearing them all the time to prevent accidental dehydration. As you can see, it is a worthwhile investment, especially if you are in a military role.
If you choose to use them more than once a day, you should check that you are using sunscreen as a sunscreen designed for the Clear Plastic Face Shields will react badly to sunscreen designed for regular sunscreen. You could get sunburned!
As the Clear Plastic Face Shields are specially designed to prevent sunburn, you need to make sure you are protected from the sun. The first step is to apply sunscreen that has been designed for this purpose.
If you have children then make sure they have had their full spectrum of sunscreen and wear sunglasses and hats to protect them. The sooner you can stop using them, the sooner you can start enjoying the benefits.
