Acrylic Plastic: The Ultimate FAQ Guide

Acrylic plastic is gaining popularity every day. As a leading manufacturer in this industry, we receive numerous inquiries about acrylic regularly.

This guide aims to provide answers to the most frequently asked questions about acrylic plastic. The goal is to help readers easily find the information they seek. Without further ado, let’s get started.

What is Acrylic Plastic?

Acrylic plastic, also known as poly methyl methacrylate, is a transparent and durable material used for various applications and as a glass substitute. Its strength, processability, and resistance make it highly sought after and widely used. It is known by several names, including Plexiglass, Perspex, and PMMA.

It is often confused with polycarbonate sheets, but they are different materials. Want to know the differences between polycarbonate and acrylic sheets?

How is Acrylic Plastic Manufactured?

Acrylic can be manufactured through two main methods: casting and extrusion. The casting process requires more labor and time, utilizing two large glass molds to form the raw material into sheets.

In contrast, extrusion is more reliant on large machinery and automated processes, making it faster and allowing for lower prices compared to casting.
