Tolong ahli2chemist skalian....skang kan dok sebuk2 pasal BPA free bottles. Polycarbonate yg bese buat bottle susu baby tuh is regarded as unsafe di western countries skang as they are afraid the BPA will leach into the babies milk/food...so derang bertukar arah ke PP bottles n glass bottles..n kat mesia nih plak as i can see and use la ....styrofoam(mcm mana nak eja daaa?)so may i know how safe these kinds of plastics...to what temp/enviroment they can stand?

Apakah itu BPA

Bisphenol A (BPA) is a chemical building block that is used primarily to make polycarbonate plastic and epoxy resins. Over four decades of extensive safety research on BPA shows that consumer products made with BPA are safe for their intended uses and pose no known risks to human health.

Polycarbonate plastic is a lightweight, high-performance plastic that possesses a unique balance of toughness, optical clarity, high heat resistance and excellent electrical resistance. Because of these attributes, polycarbonate is used in a wide variety of common products including digital media (e.g., CDs, DVDs), electrical and electronic equipment, automobiles, sports safety equipment, reusable food and drink containers, and many other products.

Epoxy resins have many uses including engineering applications such as electrical laminates for printed circuit boards, composites, paints and adhesives, as well as in a variety of protective coatings. Cured epoxy resins are inert materials used as protective liners in metal cans to maintain the quality of canned foods and beverages, and have achieved wide acceptance for use as protective coatings because of their exceptional combination of toughness, adhesion, formability, and chemical resistance
