What are the chemical properties of bisphenol A (BPA)?
BPA stands for bisphenol A. BPA is an industrial chemical that has been used to make certain plastics and resins since the 1960s. BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles. They may also be used in other consumer goods.

Are any of the #7 plastics safe? - Hello Natural Living
What are the 7 types of plastic? #1 – PET or PETE (nylon) #2 – HDPE (high density polyethylene) #3 – PVC (polyvinyl chloride) #4 – LDPE (low density polyethylene) #5 – PP (polypropylene) #6 – PS (polystyrene) #7 – Other Number 7 seems to be the dumping ground for all other types of plastic. So how do you know which #7 plastics should be avoided?
It's the Rheo Thing: BPA is not a plasticizer
(Polymerization reactions are seldom able to achieve 100% yields due to a combination of factors, including very high viscosities reducing reactant diffusion rates.) The amount of unreacted BPA is very small, far less than 1%, and far less than the concentration levels of any plasticizers.

- What makes BPA an irreplaceable ingredient in plastics?
- The secret to what makes BPA such an irreplaceable ingredient in plastics is the same thing that leads to its health risks – the molecule’s chemical structure. Bisphenol A is made of two carbon rings with small alcohol groups attached and is used to produce strong, clear plastics. Darkness3560/Wikimedia Commons
