Main Types Of Clear Plastic Sheet
These sheets are typically made from many different types of plastic materials including acrylic, polycarbonate, PVC, and PETG, each with unique properties suited for various applications.
Acrylic Sheet (Plexiglass)
Acrylic sheets, also known by brand names like Plexiglas®, are prized for their exceptional optical clarity and excellent abrasion resistance.
It can also be drilled using appropriate drill bits and techniques to avoid cracking or chipping.
It is lightweight—about half the weight of glass—and resistant to yellowing and UV damage, making it ideal for applications requiring long-term clarity, such as picture frames, signs, and display cases.
In response to the COVID-19 pandemic, acrylic sheets have become a go-to material for creating safety partitions, desktop barriers, sneeze guards, and other protective shields.
Polycarbonate Sheet (Lexan)
Polycarbonate sheets are renowned for their outstanding impact resistance and abrasion resistant surface, being over 200 times stronger than glass and significantly tougher than acrylic of the same thickness. They are also thermoplastics, allowing for easy molding and forming.
Polycarbonate is well suited for applications demanding durability and security, such as protective barriers, safety windows, and greenhouse panels. Some PC sheets come with UV protective layers to enhance outdoor performance.
PVC (Polyvinyl Chloride) Sheet
PVC, a versatile thermoplastic, ranks as the world’s third most widely used thermoplastic by volume, following polyethylene and polypropylene. Clear PVC sheets are valued for their robust chemical resistance, durability, and affordability.
Although less transparent than acrylic or polycarbonate, they are ideal for protective barriers and industrial applications where resistance to chemical exposure is critical.
PETG (Polyethylene Terephthalate Glycol) Sheet
PETG plastic sheets are transparent plastic materials made from amorphous copolyester, utilizing 1,4-cyclohexanedimethanol (CHDM) to partially replace ethylene glycol. This modification inhibits crystallization, enhancing transparency and processing performance.
PETG sheets exhibit outstanding toughness and high impact resistance, with an impact strength 3 to 10 times greater than that of modified polyacrylates. They offer a wide processing range, high mechanical strength, and excellent flexibility.
