Sheet in PMMA E Resist 65 3050x2050 mm transparent

PMMA, polymethyl methacrylate or everyday acrylic, is extruded here, that is pressed through a die in the Resist 65 version. Resist means that the material is extra impact resistant, at the price of lower stiffness than standard acrylic. It suits places where sheets take knocks, blows or strain that ordinary acrylic cannot handle.

The density is 1.19 g/cm³. The tensile modulus is 2200 MPa and the flexural strength 85 MPa. The notched impact strength sits at 6.5 kJ/m², which is several times higher than standard acrylic. The elongation at break is 15 percent and HDT/B 98 °C. Compared with standard PMMA E, Resist 65 has lost about a third of the stiffness but gained several times the impact resistance.

The rest of the material physics follows extruded acrylic: a maximum service temperature of 70 °C continuously and 90 °C for short periods, plus water absorption of around 0.2 percent after 24 hours immersed and 2.1 percent at saturation. The light transmission for transparent sheets is 92 percent at 3 mm. The building fire class is B2 per DIN 4102 and E per EN 13501. Transparent grades are approved for direct food contact under EU 10/2011.

The sheet is sawn, milled, drilled and polished with tools made for plastic. Thermoforming is done at temperatures around 150 to 160 °C for extruded acrylic. Acrylic adhesive with methyl methacrylate is the standard choice for bonding. After milling and bonding the material should be annealed to reduce internal stresses and avoid stress cracking.

Transparent and colored acrylic is used for signs, illuminated signs, machine guards, inspection hatches, store fittings, displays, aquariums, safety glazing, exhibition builds, furniture fronts and roof domes. The material weighs half as much as glass at the same thickness and does not break into sharp shards.

This extruded Resist 65 sheet is 3050x2050 mm in transparent, a format that suits both large surfaces and parts that are cut to your dimensions.
