I. Electrical Properties (The Core Advantage) 

● Excellent Dielectric Properties 

o Low Dielectric Constant:  Highly stable, approximately 2.1, remaining almost unchanged with variations in frequency and temperature. This facilitates high-speed and high-fidelity signal transmission.

o Extremely Low Dissipation Factor:  Maintains an exceptionally low value (approx. 0.0002) even at high frequencies (e.g., 10 GHz), minimizing signal loss. This is the fundamental reason for its irreplaceability in radio frequency (RF) and microwave applications.

II. Thermal Properties 

● Exceptional High and Low-Temperature Resistance:  Features an extremely wide working temperature range, from -190°C to +260°C for long-term use, with short-term tolerance exceeding 300°C. It neither embrittles at low temperatures nor softens significantly at high temperatures.

● Excellent Thermal Stability:  Does not decompose at high temperatures and possesses excellent non-flammability, complying with the highest flame-retardant ratings.

III. Surface Properties 

● Very Low Coefficient of Friction:  Possesses one of the lowest coefficients of friction among solid materials, approximately 0.05 - 0.10, resulting in outstanding self-lubrication and non-stick properties.

● Superb Hydrophobic and Oleophobic Properties:  Has an extremely low surface energy, causing it to adhere to almost nothing. Liquids like water and oil cannot wet its surface.

IV. Chemical Properties 

● Extreme Chemical Inertness:  Resistant to strong acids, strong alkalis, aqua regia, and various organic solvents, earning it the nickname "King of Plastics." It remains stable in harsh chemical environments.

V. Mechanical and Other Properties 

● Good Mechanical Toughness:  Maintains a degree of flexibility and impact resistance even at low temperatures.

● Excellent Aging Resistance:  Possesses superb weatherability; its properties remain largely unchanged after long-term outdoor exposure.

● High Volume Resistivity:  Serves as an excellent electrical insulating material.
