Overview: The Fluoroloy® A02 material datasheet from Omniseal Solutions provides detailed information on the properties and benefits of this material, which is characterized by its white color, FDA compliance, and suitability for moderate to hard vacuum service. It offers good cryogenic properties, excellent chemical resistance, low gas permeability, and improved creep and extrusion resistance.
Features & Benefits: The material is noted for its limited wear and heat resistance, with a working temperature range from -268°C to +316°C (-450°F to +600°F).
Physical Properties: The specific gravity is 2.16, and the hardness ranges from 50 to 65 Shore D, as per ASTM D792 and ASTM D2240 test methods, respectively.
Mechanical Properties: The tensile strength is 33.1 MPa (4,800 psi), elongation is 450%, tensile modulus is 620.5 MPa (90,000 psi), compressive stress at 1% strain is 8.96 MPa (1,300 psi), and compressive modulus is 572 MPa (83,000 psi). Deformation under load is 8% at 2,000 psi and room temperature.
Thermal Properties: The linear coefficient of thermal expansion is 12.6x10-5 mm/mm/°C (7.00x10-5 in/in/°F) in the mold direction and 14.8x10-5 mm/mm/°C (8.22x10-5 in/in/°F) in the cross direction.
Tribological Properties: The coefficient of friction is 0.09, as per ASTM D3702.
Notes: All testing is performed at room temperature unless otherwise specified. Compression strength was measured at 1% strain, and deformation under load was tested at 13.8 MPa (2,000 psi) for 24 hours. The values provided are typical and intended for reference only, not for design specifications or quality control.
