Transparent Plastics
Not all plastics are coloured. At Benvitec, we also frequently work with transparent plastics like PET-G (Polyethylene Terephthalate Glycol), PC (polycarbonate), and PMMA (commonly known as Plexiglas).
So what are the key differences between these clear materials—and where are they used?
pet-G
Key properties
- Good chemical resistance
- High strength and stiffness
- Lightweight
- Easy to machine
