Product catalog summary

Introduction: VALUE is a composite powder based on polyamide 12, designed for use in powder bed systems via laser sintering. It is suitable for producing models and functional parts with long life cycles and excellent chemical resistance, particularly in industries like oil, automotive, and others requiring high mechanical and surface quality parts.

Composition and Physical Properties: The powder is composed of polyamide 12 with glass beads and additives, appearing as a light grey solid. Key physical properties include an average particle size of 45-65 µm, a packed density of 1.05 g/cm³, and a part density of 1.38 g/cm³. Moisture absorption is 0.50% over 24 hours.

Mechanical Properties: The material exhibits high mechanical strength with a Young's modulus of 3100-3300 MPa and a flexural modulus of 3000 MPa. Tensile strength averages 35 MPa in the XY direction and 30 MPa in the Z direction, with elongation at break estimated at 12% and 8% respectively. These properties can vary based on processing conditions.

Thermal Properties: The melting point ranges from 180 to 186°C, with a processing temperature around 174°C. The material is classified under UL-94 for flammability, indicating its fire resistance.

Chemical Properties: VALUE is insoluble in water and most organic solvents but soluble in mineral acids and phenols. It offers good resistance to alkaline substances, hydrocarbons, oils, and solvents, with some susceptibility to acid attack.

Electrical Properties: The material has a volume resistivity of less than 1 E+11 Ohms/m, making it antistatic according to CEI 93 standards.

Surface and Finish: The natural coloration is light grey with a Shore D hardness greater than 80. Surface roughness after processing is estimated at 8 µm, improving to 5 µm after finishing.

Safety and Handling: The decomposition temperature is above 400°C, and the material can form explosive dust mixtures in air. It is classified as explosibility class St2.

Conclusion: VALUE is a versatile material offering excellent mechanical, thermal, and chemical properties, suitable for various industrial applications requiring durable and high-quality parts.
