Customization options

1.Precision Cutting to Size
PMMA sheets can be cut to precise dimensions according to customer drawings or specifications, using CNC, sawing, or laser cutting for smooth, accurate edges and minimal material stress.

2.Custom Shapes & Profiles
Beyond standard rectangular sheets, PMMA can be machined into complex shapes, slots, holes, or curved profiles. Polishing or edge finishing ensures optical clarity and professional aesthetics.

3.Thickness & Dimension Adjustments
Standard thickness ranges from 1mm to 30 mm; custom thinner or thicker sheets can be produced upon request. Tight tolerances are maintained to meet demanding applications such as displays, signage, or optical components.

4.Color Options
Clear (transparent) PMMA is standard, with optional colors including frosted, smoked, red, blue, or custom hues according to RAL/Pantone codes. Colored or tinted sheets maintain excellent light transmission and surface gloss.

5.Material Grades
Various PMMA grades are available, including optical-grade for high transparency, UV-resistant for outdoor applications, impact-modified for improved toughness, and anti-static or abrasion-resistant grades for specialized industrial use.

Q&A

Q

What is PMMA, and what are its main properties?

PMMA (Polymethyl Methacrylate), also known as acrylic or plexiglass, is a transparent thermoplastic known for its excellent optical clarity, high light transmission (up to 92%), and glossy surface finish. It is lightweight, rigid, weather-resistant, and easy to fabricate. PMMA is more scratch-resistant than glass and can be easily cut, drilled, polished, or thermoformed into complex shapes. It is ideal for applications requiring transparency, durability, and aesthetics.

Q

What thicknesses, sizes, and colors are available for PMMA sheets?

Standard thicknesses range from 1 mm to 30 mm, but custom thicknesses are available on request. Common sheet sizes include 1000x2000mm, 1220x2440mm, and other cut-to-size options. Transparent (clear) is the most popular, but PMMA sheets are also available in frosted, smoked, red, blue, green, or custom colors according to RAL/Pantone codes. Colored sheets retain high clarity and gloss.

Q

Can PMMA sheets be cut, drilled, or thermoformed?

Yes. PMMA sheets are highly machinable. They can be cut with saws, CNC routers, or laser cutters; drilled without cracking; and thermoformed into curved or complex shapes. Polishing or flame-polishing can restore optical clarity to edges. For best results, sharp tools and moderate cutting speeds are recommended to avoid chipping or heat damage.

Q

What are the common applications of PMMA sheets?

1.Signage & Displays: Light boxes, shop signs, exhibition displays, protective screens.

2.Architecture & Interior Design: Partitions, balustrades, decorative panels, skylights.

3.Electronics & Optics: Light guides, lenses, and instrument covers.

4.Consumer Goods: Furniture, aquariums, picture frames, and protective covers.
Its combination of clarity, weather resistance, and ease of fabrication makes it ideal for both indoor and outdoor applications.

Q

How should PMMA sheets be stored and handled?

PMMA sheets should be stored flat in a cool, dry place away from direct sunlight and heat sources. Avoid stacking heavy objects on top to prevent warping. Keep protective film on the sheet until final installation to prevent scratches. During transportation, handle sheets carefully to avoid bending or impact damage.

Q

What are the limitations of PMMA sheets?

While PMMA is strong and transparent, it is more brittle than polycarbonate (PC) and can crack under high impact. Prolonged exposure to UV may cause slight yellowing unless UV-resistant grades are used. It is soluble in some solvents (like acetone) and can be scratched by abrasive materials. PMMA is best for applications where optical clarity is critical, but extreme impact resistance is not required.

Q

Can PMMA sheets be customized for special projects?

Absolutely. Manufacturers can provide custom thicknesses, sizes, colors, and surface finishes. PMMA can also be cut, drilled, engraved, thermoformed, or polished to meet specific design requirements. For outdoor projects, UV-resistant or weather-stable grades are available, and flame-retardant grades can be selected for safety-critical applications.

Q

Is PMMA sheet impact-resistant?

Yes, PMMA sheets are much stronger than glass, though polycarbonate sheets provide higher impact resistance.
