What exactly is Plexiglass Coulé (PMMA) and how does it work

PMMA is an abbreviation for polymethyl methacrylate, but it is more commonly referred to as plaque plaque plexiglass couleur couleur teinté or Plexiglasses

PMMA is an abbreviation for polymethyl methacrylate, but it is more commonly referred to as plaque plaque plexiglass couleur couleur teinté or Plexiglasses. PMMA is available in two different qualities: cast PMMA and extruded PMMA. Cast PMMA is the more common type of PMMA. The ingredients are the same, but the method of production is completely different from one another. Extruded PMMA, which is a more cost-effective alternative to cast PMMA, is made from PMMA pellets that have been heated to softening temperatures in preparation for extrusion. Although the visual quality is excellent, it is more susceptible to external attacks and will therefore age more quickly than Cast PMMA.

Cast PMMA represents the highest quality of this material; it is produced by pouring monomer (MMA) between two glass sheets prior to polymerization; the material has no internal stress and is more homogeneous than the characteristics of extruded PMMA; and it is more durable than extruded PMMA. Over time, this increases the material's resistance to chemicals and ultraviolet rays. As a result, it is employed in a wide range of plastic processing applications.

 

 


es cast plaque plexiglass teinté teinté couleur plate has the following characteristics:

Transparency: It has an unrivaled transparency of 92%, which is higher than standard glass, which has an average transparency of 89%.

Optical Appearance: Cast PMMA is the most visually appealing material, and it is available in a wide range of finishes and colors.

Molding: Cast PMMA is a versatile material that offers a wide range of deformation possibilities while being simple to use and maintain.

Rigidity: Plastic materials have a relatively high degree of rigidity.

Impact Resistance: The impact resistance is quite high, significantly higher than that of glass, but slightly lower than that of polycarbonate, which is the industry standard in this field.

With the exception of fluorescent and mirror references (which are intended for indoor use only), cast PMMA is extremely UV stable. The major brands we offer guarantee their plates for between 10 and 30 years, depending on the brand.

Chemical Resistance: Chemical resistance is excellent; however, because it is a plastic material, it is sensitive to certain solvents, such as acetone. For more information, refer to the Cast PMMA Chemical Compatibility Chart, which can be found at the bottom of this page.

Cast PMMA has a very low fire rating (M4), but it has the significant advantage that, in contrast to other higher-rated materials, plexiglass teinté emits very little smoke and is completely non-toxic, making it an excellent choice for firefighting. In the rest of the EU, this is the most important point to remember.
