What is Perspex called in USA?

In the United States, Perspex is known by a different name. The plastic is commonly referred to as Plexiglass, which is a brand name that has become synonymous with acrylic plastic. The name Plexiglass is derived from the words "plexi" and "glass," which describe the plastic''s transparent and glass-like appearance.

Initially, Perspex was sold under the same name in the US market. However, in the 1930s, a company called Rohm and Haas began selling a similar acrylic plastic under the name Plexiglas. The name became so popular that it was eventually used as a generic term for all acrylic plastics in the US.

Why is Perspex called Plexiglass in the USA?

The reason why Perspex is called Plexiglass in the USA can be traced back to the history of acrylic plastic production in the country. In the 1930s, Rohm and Haas introduced their own brand of acrylic plastic, which they named Plexiglas. The plastic was marketed as a cheaper alternative to glass and quickly became popular in various applications.

As the use of Plexiglas increased in the US market, the name became synonymous with acrylic plastic. In fact, it became so popular that competing brands of acrylic plastic, including Perspex, were marketed under the same name. This led to confusion among consumers, and eventually, Perspex was marketed under a different name to avoid trademark infringement.

What are the differences between Perspex and Plexiglass?

Despite having different names, there is very little difference between Perspex and Plexiglass. Both types of plastics are made from methyl methacrylate and have similar properties, including excellent optical clarity and impact resistance.

However, there are some differences in the way the plastics are manufactured. Perspex is manufactured by Lucite International, while Plexiglass is produced by various companies. The manufacturing process for Perspex involves a continuous casting method, while Plexiglass is manufactured using a cell cast process.

In terms of price, both Perspex and Plexiglass are relatively affordable compared to other plastics. The cost will depend on the thickness and size of the sheet.

Conclusion

Perspex and Plexiglass are two names that refer to the same plastic, which is a type of acrylic plastic made from methyl methacrylate. In the USA, the plastic is commonly known as Plexiglass due to the popularity of the brand name. Perspex and Plexiglass have similar properties and are widely used in various applications. Despite the difference in name, both plastics are affordable and offer excellent optical clarity and impact resistance.
