PMMA (Acrylaat / Plexiglas)

Plastic

PMMA, in full polymethyl methacrylate, is a transparent thermoplastic known for its crystal-clear appearance and high scratch resistance. This material is a popular alternative to glass: it is lighter, stronger, UV-resistant and easy to work with. PMMA is widely used in applications where clarity, aesthetics and weather resistance are important.
Well-known trade names of PMMA include Plexiglas®, Altuglas®, Perspex® and Setacryl®.

Frequently Asked Questions about PMMA

What is the difference between PMMA and polycarbonate?

PMMA is more transparent and scratch-resistant but less impact-resistant than polycarbonate. Choose PMMA where optical clarity is critical; choose PC for high-impact applications.

Can PMMA be used outdoors?

Yes PMMA is highly UV-resistant and does not yellow, making it ideal for outdoor uses like façade lettering, canopies, or billboards.

Is PMMA food-safe?

Yes many PMMA grades are approved for food contact. Check the certification for the specific sheet.

Can PMMA be bent?

Yes PMMA can be thermally bent. Cold bending is possible but requires a larger bend radius to avoid cracking.

Is PMMA scratch-sensitive?

PMMA is harder and more scratch-resistant than most plastics, though not as hard as glass. You can apply a protective coating for extra scratch resistance.

How is PMMA machined?

PMMA can be sawn, milled, drilled, polished, and laser-cut. Laser cutting yields a smooth, glossy edge.

Is PMMA recyclebaar?

Yes PMMA is highly recyclable. Reclaimed PMMA is often reused in the production of new sheets. Cast PMMA (GS) is stress-free, easier to machine, and more chemically resistant; extruded PMMA (XT) is more economical and offers tighter thickness tolerances.

What alternatives exist for high-impact applications?

For higher impact resistance, polycarbonate (PC) or PMMA-PC co-polymer are suitable alternatives.

Frequently Asked Questions about PA6

What is the difference between PA6 and PA66?

PA6 has slightly lower crystallinity than PA66, making it tougher but less dimensionally stable. PA66 is stiffer and offers somewhat higher heat resistance.

Is PA6 suitable for food applications?

Yes, natural-color grades of PA6 are often FDA- and EU-compliant and suitable for food-processing use.

How well does PA6 handle moisture?

PA6 absorbs relatively high moisture (up to ~1.5%), which affects dimensional stability. For tight-tolerance parts, drying or an alternative like POM is recommended.

Is PA6 easy to machine?

Yes, PA6 machines very well by milling, turning, and drilling. It produces good chips and is ideal for secondary finishing.

Can PA6 be used outdoors?

PA6 has limited UV resistance. For outdoor use, UV-stabilized or black-pigmented grades are recommended.

What fillers are available for PA6?

Available variants include glass-filled (for higher stiffness), molybdenum disulfide-filled (for improved sliding), or oil-impregnated for self-lubrication.

Is PA6 suitable for dynamic loading?

Absolutely, PA6 excels in sliding and rolling applications thanks to its good wear resistance and damping behavior.

Can PA6 be laser-cut?

Although technically possible, milling or sawing is often more efficient due to potential discoloration or fumes when laser cutting.
