During the 1970s and 80s, a few if not a lot of clothes had the mention of "acrylic" on the inside label.
Usually pullover and sweatshirts would be not as soft as they are nowadays.
Acrylic was the material of that time - a bit like formica for kitchen tables and chairs. It was durable laminated plastic which could resist shocks and stains. Then furniture fashion and trends changed for wood tops and then stainless steel or glass, without forgetting marble or granite.
Acrylic has not disappeared. In fact, it seems that it is part of the engineers' secret toolbox.
Have you heard of tesa 4965? Indeed tesa, the adhesive tape - "...a tackyfied acrylic adhesive...".
Tesa is now part of the aviation sector - and this is not about toys or models but real full size planes.
Remember a few weeks back (May 2015) when someone spotted something rather odd on an EasyJet passenger plane?
In this case, this is called "speed tape" very resistant too.
...aluminised pressure-sensitive tape used for minor repairs on aircraft and racing cars until a more permanent solution can be found. Resistant to water, solvents, flames, UV light and heat the tape can also be used to repair bullet damage to combat aircraft... Source
Overall, people like to know what is exactly going on and why tape is used to fix the structure of a plane. Questions are emerging: is it safe to fly with a piece of tape to hold things together? Knowing that an airplane has to face pressure and extreme temperature too!
But, it is not normal material... even if it looks basic. Its texture and components are made to last whatever the weather.
When you think that some manufacturers are producing promotional acrylic coasters made to resist the heat of a cup of tea/coffee, it clearly shows that it is a versatile synthetic fibre.
Of course, there might be a difference between high-tech acrylic tape and the one used to make beermats. Meanwhile, it is to show that some "old tricks" can still be used in the 21st century where everyone believe that digital technology is the way forward!
"Never say never" is still applicable!
