Re: COVID-19 and GPSL



Some evidence, But not totally also.

I wonder how must is lost when the latex is NOT stressed?

Like stretched ONLY to 50% elongation.

We have tension tested many many samples of latex, and it is amazing on how linear the force is when a piece is being stretched. From barely stretched to right at the end like 99% of it's stretchability  the forces only change like 10%

But that last bit it the force to pull it any further skyrockets! ten times or more the rest of the force, and the amount it continues to stretch is like nothing.

You can even easily feel this by hand. Take a scrap of a balloon and cut say a 1" wide strip from it. Now start to pull,  the force is more or less the same then it like hit a brick wall where it does not want to let you stretch any more then finally breaks.

Hence the flight that lasted two or three days that went from California to Morocco.

May 1, 2019 - al (2013) examined the degradation of latex films in different environments. The degradation rate was most strongly linked to treatments with the most solar radiation, causing the fastest rate of breakdown. Photo-oxidation was the primary pathway for this degradation. This occurred in response to UV light from the sun.
