PolyGlass is the new generation of co-polyester. It represents the future of baby bottles. Polyglass is a high clarity material similar to glass with the flexibility of plastic. More importantly, it is BPA free and safe for your baby.
The research of PolyGlass started few years ago. It went through numerous and vigorous laboratory testing that materials for food industries go through. Some of the most important test are FDA Part 175-181 and SGS IEC 62321-5-2013 which are recognized by most countries in the world. PolyGlass is an Eco-friendly bio co-polyester which is created using natural materials based on the extract from plant materials. It does not release the xenoestrogen, Bisphenol A (BPA).BPA is a xenoestrogen mimics endocrine hormones and thus has the unintended and possibly far-reaching effects on people with physical contact with the chemical and is present in some plastic materials.PolyGlass is an excellent resin which have chemical resistance and food stain resistance among the transparent resin used in food contact applications.
Its low oxygen permeability is useful for food storage container such as the airtight container and baby feeding bottles.Other than meeting the requirements of baby feeding bottles, PolyGlass have the following qualities.
High heat deflection temperature.
High impact-hardness (similar to glass)
High gloss and clarity
Elemental migration free
Heavy metal content free
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.
Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance.Polypropylene is the second-most widely produced commodity plastic (after polyethylene) and it is often used in packaging and labeling.
In 2013, the global market for polypropylene was about 55 million tonnes.
Silicon is a chemical element with symbol Si and atomic number 14. It is a hard and brittle crystalline solid with a blue-grey metallic lustre; and it is a tetravalent metalloid and semiconductor.
It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was not until 1823 that Jöns Jakob Berzelius was first able to prepare it and characterize it in pure form. Its melting and boiling points of 1414 °C and 3265 °C respectively are the second-highest among all the metalloids and nonmetals, being only surpassed by boron.
Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure element in the Earth’s crust. It is most widely distributed in dusts, sands, planetoids, and planets as various forms of silicon dioxide (silica) or silicates. More than 90% of the Earth’s crust is composed of silicate minerals, making silicon the second most abundant element in the Earth’s crust (about 28% by mass) after oxygen.
