Weather Resistance
Perspex sheet is stable against UV radiation and does not yellow easily, which makes it suitable for outdoor use, such as in signs or glazing for greenhouses.
Manufacturing Process of Perspex Sheet
Extrusion
One of the common methods for manufacturing perspex sheets is extrusion. In this process, polymethyl methacrylate (PMMA) pellets are heated and forced through a die to create a continuous sheet. This method is cost-effective and suitable for producing sheets of consistent thickness.
Cell Casting
Cell casting, or bulk polymerization, involves pouring liquid acrylic between two sheets of glass and allowing it to cure. This method yields sheets with exceptional optical clarity but can be more labor-intensive and costly.
Injection Molding
Injection molding is used to create complex shapes and designs from acrylic. It involves injecting melted acrylic into a mold and allowing it to cool and solidify. This process is often employed for manufacturing intricate acrylic products.
Types of Perspex Sheet
Clear Perspex: This is the standard, clear acrylic sheet that most people associate with Perspex. It offers excellent optical clarity and is commonly used for windows, protective screens, displays, and signage.
Colored Perspex: Acrylic sheets can be tinted or colored during the manufacturing process to achieve a wide range of colors. Colored Perspex sheets are used for decorative purposes, signage, and artistic projects.
Opal Perspex: Opal or opaque Perspex sheets are translucent but not transparent. They diffuse light, making them ideal for lightboxes, signs, and architectural applications where a soft, even illumination is desired.
Mirror Perspex: Mirror acrylic sheets have a reflective surface similar to a traditional glass mirror but are much lighter and more durable. They are used in interior design, retail displays, and decorative applications.
Frosted Perspex: Frosted acrylic sheets have a matte, textured surface that diffuses light and provides privacy. They are often used for partitions, shower screens, and decorative elements.
UV-Resistant Perspex: Some acrylic sheets are treated to be UV-resistant, which makes them suitable for outdoor applications. They can withstand prolonged exposure to sunlight without yellowing or becoming brittle.
Fluorescent Perspex: These acrylic sheets are infused with fluorescent pigments, making them glow under UV or blacklight. They are popular for signage, artwork, and decorative installations.
Anti-Glare Perspex: Anti-glare acrylic sheets are designed to reduce reflections and glare, making them suitable for picture framing, museum displays, and electronic device screens.
Impact-Resistant Perspex: This type of acrylic sheet is engineered to be more impact-resistant than standard acrylic. It is used in applications where increased durability and resistance to breakage are essential.
Fire-Retardant Perspex: Fire-retardant acrylic sheets are formulated to meet fire safety regulations. They are used in buildings and areas where fire safety is a concern.
How to Choose Perspex Sheet
Thickness
Perspex sheets come in various thicknesses, ranging from thin films to thick slabs. Select the appropriate thickness based on the application's structural requirements and weight considerations.
Size
Measure the area where the Perspex sheet will be installed to ensure it fits properly. Custom sizes can often be ordered if standard sizes do not suit your needs.
Color and Transparency
Determine whether you need clear, colored, or frosted Perspex. Clear Perspex is most common for its transparency, but colored or frosted options can be chosen for aesthetic or privacy purposes.
Hardness
Perspex sheets are available in different hardness levels. Higher hardness is generally more resistant to scratches and impacts but can be more difficult to work with during fabrication.
Fire Rating
If the Perspex sheet will be used in an environment with strict fire regulations, select a grade that meets the required fire resistance standards.
UV Resistance
For outdoor use or areas exposed to sunlight, choose a UV-resistant Perspex to prevent yellowing and degradation over time.
How to Maintain Perspex Sheet
Prevent high temperature
The temperature of the perspex sheet should not exceed 90 degrees during continuous use.Because the thermal deformation of the general perspex sheet is stable at about 100 degrees,The temperature of the general perspex sheelt at 98 ℃ will cause thermal deformation, so high temperature deformation of acrylic products should be prevented.
Avoid touching with sharp objects
The perspex sheet is actually a kind of organic plastic. Although the general hardness can meet many application scenarios, if there is a special purpose, then we can harden the perspex shee to prevent scratches, so that its hardness can reach 3H.If the perspex shee encounters harder things such as nails and other pins, at this moment we can increase the hardness of the perspex sheelt to 6H,
Soft towel + 1% soapy water for decontamination
If the perspex sheet is blurred or unclean due to slight scratches or dust adsorption caused by static electricity,Or there will be a layer of gray on the perspex shee for other reasons.We recommend cleaning with 1% soapy water and a soft cloth.Scrubbing in this way is not only clean, but also not easy to stain the dust layer again. And it does not need to be rinsed with clean water again, which is convenient to clean and is not easy to leave hand marks on the perspex shee.
Pay attention to thermal expansion and cold contraction
When maintaining the perspex sheet, you will generally encounter characteristics. The length, width and height of the perspex sheelt will increase, but it will decrease in winter.This is because the perspex sheelt has a certain expansion coefficient, so the factory should consider the thermal expansion and cold contraction coefficient of the acrylic panel during the installation process,And take into account the stretching gap during assembly. This is the detail that must be paid attention to in the process of assembling the perspex sheelt.roduct.
