Acrylic Round PMMA Rod Acrylic Round PMMA Rod Acrylic Round PMMA Rod
Clear Extruded Acrylic Round PMMA Rods
Our Extruded Acrylic/Plexiglass rods exhibit durability, scratch resistance, and toughness surpassing that of glass, making them an ideal choice for a variety of projects! These rods are available in various shapes and sizes, with lengths of 6 feet. If you require custom sizing, please reach out to us.
Crafted from extruded acrylic material, these PMMA rods retain the workable properties of acrylic sheets but take on the cylindrical form of a rod.
Two distinct manufacturing techniques are employed in creating PMMA acrylic rods.
The first method involves casting the PMMA acrylic material into the desired rod diameter, known as cast acrylic rods, providing the finest optical finish. Additionally, cast acrylic rods offer a wide range of diameters, reaching up to 200 mm. The second technique is extruding the acrylic into the required cap diameter, resulting in extruded acrylic rods. This method offers a cost-effective alternative to cast acrylic when aesthetic considerations are less critical.
