Acrylic is a type of plastic manufactured from one or more derivatives of acrylic acid. The materials used in the formation are Polymethyl Methacrylate acrylic, or PMMA. It is one of the most widely used forms due to it’s exceptional capability of resisting weather, strength, clarity and versatility. There are a variety of grades for acrylic polymer which are suitable for extrusion, injection, moulding and several other manufacturing processes.
The final result is transparent, translucent, opaque and also coloured polymers that are available with different levels of light transmissions, heat resistance, flow rates, strength impact and release capabilities. PMMA acrylic sheets have the quality similar to glass with excellent clarity, However, this depends on the chemical formation and molecular bonding within the sheets. Even the weight and the impact resistance depend on the chemical bonding. With the help of acrylic manufacturers, the acrylic sheets can be tinted, mirrored or made opaque. Different forms of coatings can be applied to the sheet or finished part to increase the performance like anti fogging, scratch resistance, glare reduction and solar reflectivity.
The option of glare reduction is often chosen in terms of Perspex signage. Moreover, acrylic materials are thermoplastic and soften under extreme temperatures (high). This means depending on the promotional aspects, your signage can be formed to virtually any shape with brilliant durability, weather resistance capability that often stand superior when compared to other plastics.
Physical benefits of acrylic material
- Formable – With just a small amount of heat, it’s easy to shape and mold.
- Durable – Impact resistance that stands for a prolonged period.
- Weatherable – Stands to the elements much longer than any other plastic.
- Non-Yellowing – A minimum of 20 years of limited warranty that guarantees no yellowing.
Today, Perspex shop front signage are made of acrylic products mainly for their high quality, exceptional clarity, ease in processing and design flexibility.
How the sheet is formed?
Extruded acrylic sheets are manufactured every day to meet the world’s demands. Extrusion is a form of continuous production where acrylic polymers are fed into a barrel of extruder that further heats them until they are a molten mass. The mass is then slowly poured through a screw into the barrel and forced out of the end through a die in the form of a molten sheet. The spacing in the sheet determines the thickness of the surface.
The benefits of acrylic materials depend on the process of formation and the type of polymer used.
