The formulation combines high mechanical strength, long-term toughness, and impact resistance for functional parts ranging from prototyping to detailed production components.\u003cbr\u003e\u003cbr\u003eThe resin is available in several color variations. Its processing speed and the resulting surface finish are highlighted by the manufacturer as key differentiators compared to standard resins on the market.\u003c\/p\u003e\n\u003ch2\u003eMechanical Behavior\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eTensile modulus reaches 2300 MPa and tensile strength 60 MPa, with an elongation at break of 25%. Flexural strength is 110 MPa (modulus 2400 MPa) and Shore D hardness is 80. Notched Izod impact tests yield 30 J\/m at 23 °C and 20 J\/m at -30 °C, indicating maintained performance at low temperatures. Unnotched Izod impact at 23 °C is 509 J\/m and notched Charpy impact is 1.3 kJ\/m².\u003c\/p\u003e\n\u003ch2\u003eThermal Stability and Applications\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe heat deflection temperature (HDT) is 73 °C at 0.45 MPa and 61 °C at 1.82 MPa, which broadens the thermal usage range compared to standard resins. The UL 94 fire rating at 1.5 mm is HB. The resin is intended for prototyping, housings, highly detailed or textured parts, and custom tools and gadgets.
