Stress from fasteners, plastic welding and molding render polycarbonate susceptible to stress corrosion cracking when it comes in contact with certain accelerants such as salt water and plastisol. It can be laminated to make bullet-proof "glass" , although "bullet-resistant" is more accurate for the thinner windows, such as are used in bullet ...
Polycarbonate (PC) PC is a clear plastic used to make bottles for milk and water. Five-gallon water bottles are a common application of PC. Polypropylene (PP) PP is used primarily for jars and closures. It is rigid and is a barrier to moisture. Polypropylene is stable at temperatures up to 220 °F (104 °C).
The use of these compounds is diminishing due to restrictions on brominated flame retardants. The reaction of BPA with phosphorus oxychloride and phenol forms BADP, which is used as a liquid flame retarder in some high performance polymer blends such as polycarbonate/ABS mixtures that are used to form the casings for household electronics.

But the researchers also detected polypropylene (the plastic used to make yogurt cups and rigid takeout food containers), polyvinylchloride (which is used in most water pipes), and styrene ...
A water bottle is a container that is used to hold liquids, mainly water, for the purpose of transporting a drink while travelling or while otherwise away from a supply of potable water. Water bottles are usually made of plastic, glass, metal, or some combination of those substances.
Since the 1960s, plastic production has surged with the advent of polycarbonate and HDPE, widely used in various products. [138] In the 1980s and 1990s, plastic recycling and the development of biodegradable plastics began to flourish to mitigate environmental impacts.
Polycarbonate polyols are more expensive than other polyols and are thus used in more demanding applications. [31] [32] They have been used to make an isophorone diisocyanate based prepolymer which is then used in glass coatings. [33] They may be used in reactive hotmelt adhesives. [34] All polyols may be used to produce polyurethane prepolymers.
Plastic straws cost under two cents per unit, according to Clean Water Action, a group working to elect environmental candidates. But biodegradable straws made by Good Start Packaging cost just ...
