Re: Off gassing?
Found this on another forum...
[i][as many new-car buyers find out, the huge amount of plastic in automobile interiors can emit chemicals that not only smell terrible but also deposit oily films on interior windows.
Many new car owners complain about a stubborn deposit of film that builds up on the inside of the windshield. No amount of glass cleaner seems to keep the film from forming. The problem is not that the glass cleaner is failing to remove the film, but rather that a new deposit of vinyl film forms after awhile.
Soft vinyls can be composed of up to 50% plasticizers, which are chemicals added to standard polymers that make them soft. Lots of vinyls contain plasticizers, but inside a car they pose a special problem.
A car parked in the sun can reach temperatures above 120 degrees, hotter than the volatility point of plasticizers. When the volatility point is reached, molecules of the plasticizers become gaseous and then condense on the coolest surface. Typically, that includes the windshield./i]
