Perspex is a type of plastic known as poly(methyl methacrylate) or PMMA. It is a synthetic polymer derived from methyl methacrylate and was discovered in the early 1930s by British chemists Rowland Hill and John Crawford at Imperial Chemical Industries (ICI) in the United Kingdom. ICI registered the product under the trademark Perspex, and it was first brought to market in 1933. Perspex is often used as a lightweight and shatter-resistant alternative to glass and has various applications, including in windows, skylights, picture frames, and lighting fixtures. It is also known for its excellent optical clarity, weather resistance, and durability.

Perspex is a trade name for acrylic
Acrylic was first produced in 1928 and brought to the market by Rohm and Hass Company around 1933. It was initially used during World War II for products such as airplane windows, canopies, and turrets. Acrylic is commonly sold in sheets of various thicknesses but can also be found in forms such as rods or tubes, and styles such as frosted, mirrored, or non-glare. It can also be moulded and coloured to fit specific applications.
Acrylic is made of a polymer called polymethyl methacrylate (PMMA). It is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic, used as an engineering plastic. It is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes.
PMMA has a good degree of compatibility with human tissue and is used in the manufacture of rigid intraocular lenses implanted in the eye during cataract treatment. It is also used in tanning beds as the transparent surface that separates the occupant from the tanning bulbs. Sheets of PMMA are also commonly used in the sign industry to make flat cut-out letters.
As the Perspex brand grew in popularity over the years, the term "perspex" became a synonym for acrylic. Consumers now use the term to reference the product, not the brand. This type of association can happen when a brand becomes so popular with one specific product. For example, the term "hoover" is now used as a universal way to describe a vacuum cleaner, regardless of the brand.

Acrylic is a plastic polymer
Acrylic is a popular alternative to glass due to its impact resistance, lightweight, and shatter-resistant properties. It is also easy to fabricate, making it ideal for custom-made products and projects. Additionally, it is UV-resistant, which means that it won't yellow or become brittle over time when exposed to sunlight. Acrylic is commonly used in sheet form and can be easily cut to size, making it a widely accessible and affordable material.
Acrylic has excellent optical clarity, weather resistance, and durability, which has led to its popularity in manufacturing and DIY projects. It is commonly used for windows, skylights, picture frames, lighting fixtures, and fibre optic cables. Acrylic is also used in the medical field, such as in intraocular lenses implanted in the eye during cataract surgery.
Perspex is a trademarked name for acrylic, or more specifically, for PMMA. It was trademarked by Imperial Chemical Industries (ICI) in the UK in 1934 and has since become a synonym for acrylic. Perspex is considered a premium type of acrylic, offering the highest benefits and special features for specific customer requirements. While acrylic can be used outdoors between temperatures of −40° Celsius and +80° Celsius, Perspex offers additional benefits that make it suitable for more specialised applications.

Acrylic is a shatter-resistant alternative to glass
Perspex is a trade name for polymethyl methacrylate (PMMA), a type of plastic also known as acrylic. Acrylic is a shatter-resistant alternative to glass. It is a synthetic polymer derived from methyl methacrylate. Acrylic glass, as it is sometimes known, is a lightweight and shatter-resistant alternative to glass. It can be used in sheet form and is often used for signage, retail display cases, and window glazing.
Acrylic is a versatile material that comes in a range of colours and finishes. It is widely accessible and affordable, and it can be easily cut to size. It is commonly used in both indoor and outdoor settings. Acrylic is an excellent replacement for glass in terms of impact resistance and weight. It can be polished to a shiny finish, making it suitable for modern homes, offices, and commercial centres.
Acrylic sheets are ideal for homes with children as they are shatter-resistant, durable, and safe. They can be used for windows, room dividers, and even as a protective layer over artwork displays or bulletin boards. Acrylic sheets are also water-resistant, making them a practical choice for bathrooms, as they are easy to clean and maintain.
Acrylic is a strong replacement for glass and can be transparent or opaque. It is lightweight, affordable, and versatile. Acrylic sheets can be cut, resized, or reshaped on the spot to fit specific structural parameters, whereas glass would need to be modified off-site. Acrylic is an industrial-grade thermoplastic that is formulated for applications requiring durability, temperature resistance, and impact resistance.
Acrylic is also used in medical applications. It is compatible with human tissue and is used in the manufacture of intraocular lenses for cataract surgery. Acrylic is also used in medical and life sciences accessories and furnishings, as well as testing containers for food and beverages.

Acrylic is used in medical applications
Perspex is a trade name for polymethyl methacrylate (PMMA), a type of plastic also known as acrylic. Acrylic is widely used in medical applications due to its durability, versatility, optical clarity, and chemical resistance.
One of the key advantages of acrylic in medical applications is its optical clarity. Acrylic offers excellent light transmittance, with up to 92% light transmittance and particular clarity at lower wavelengths of 270 to 350 nm. This makes it ideal for disposable medical diagnostics, such as blood cuvettes, drug testing devices, and laboratory equipment. Acrylic's high UV-light transmittance also makes it suitable for use in tanning beds, allowing UV rays to pass through while providing a transparent surface.
Acrylic is also known for its durability and toughness. It has good mechanical strength, dimensional stability, and high tensile and flexural strength. These properties make it suitable for medical devices that require impact resistance, such as test kits, syringes, luers, blood filters, and surgical trays. Acrylic can also be impact-modified to improve its toughness, making it suitable for applications that require increased impact resistance.
Another advantage of acrylic in medical applications is its chemical resistance. Acrylic polymers are resistant to many biological and chemical agents, making them suitable for use in areas where hygiene and durability are important. Acrylic resin coatings, for example, can be easily cleaned and maintained, providing a hygienic surface for flooring in high-traffic areas.
Acrylic is also used in medical adhesives due to its strong adhesion, versatility, and temperature resistance. Acrylic-based adhesives are preferred for direct skin-contact applications, such as wound care and wearable medical devices like glucose monitors and insulin pumps. They offer gentle removal, secure adhesion, and breathability, enhancing patient comfort and safety.
In addition, acrylic has been used in dental applications, such as super-strong prosthetic teeth that offer a superior fit and outstanding aesthetics. Acrylic has also been used in ophthalmology, with PMMA being compatible with human tissue and used in the manufacture of intraocular lenses for cataract surgery.
