PTFE Phillips Flat Head Screws

Polytetrafluoroethylene (Teflon or PTFE), commonly known as the "plastic king," has essential characteristics:

High-temperature resistance: use working temperature up to 250℃.

Low-temperature resistance: good mechanical toughness; even if the temperature drops to -196℃, it can maintain 5% elongation.

Corrosion resistance: to most chemicals and solvents, showing inertia, resistance to strong acids and alkalis, water, and various organic solvents.

Weather Resistant: It has the best aging life of any plastic.

Highly lubricating - has the lowest coefficient of friction of any solid material.

Non-adhesion: Has the lowest surface tension of any solid material and does not adhere to any substance.

Non-toxic: physiologically inert, no adverse reaction as artificial blood vessels and organs implanted in the body for a long time.

Material characteristics of polytetrafluoroethylene:

1. PTFE is one of the most temperature-resistant materials among commercially produced plastics. It can withstand a maximum service temperature of up to 260°C and maintain its stability and performance in harsh environments. This makes PTFE widely used in high-temperature processes and applications, such as chemical, automotive, aerospace, and other fields.

2. Excellent non-stick properties: PTFE has excellent non-stick properties and is widely used in areas where anti-stick coatings are required. Its surface has low surface energy, so the adhesive can not be firmly adhered to it. This makes PTFE materials ideal for cooking utensils, chemical containers, and manufacturing conveyor belts and gaskets.

3. Typical application: Non-stick baking sheets. PTFE materials are widely used in the manufacture of non-stick baking sheets. These baking trays effectively prevent food from sticking and reduce cleaning during cooking. ptfe material has excellent high temperature and chemical resistance, making it the material of choice for manufacturing non-stick baking trays.

4. Good chemical stability: PTFE material has excellent stability in various chemical environments. It resists corrosion and is resistant to common chemicals such as acids and alkalis. This makes PTFE widely used in the chemical industry, such as manufacturing pipelines, tanks, valves, and other equipment.

5. Excellent electrical insulation properties: PTFE has excellent electrical insulation properties and is one of the leading insulating materials. Its electrical insulation properties are still excellent, even in high temperatures and humid environments. This makes PTFE widely used in electrical and electronic fields, such as the manufacture of cables, insulating tubes, etc.

6. Low coefficient of friction and wear resistance: PTFE material has an extremely low coefficient of friction, making it very slippery. This makes PTFE widely used in manufacturing bearings, seals, and slides. In addition, PTFE's abrasion resistance is also excellent, and it can maintain superb performance under high pressure, high temperatures, and harsh working conditions.

7. Excellent Mechanical Properties: PTFE material has excellent mechanical properties, exhibiting high tensile strength and impact resistance. It has a low stiffness and can maintain good elasticity over a wide temperature range. This makes PTFE widely used to manufacture gaskets, seals, pipes, and shaped parts.

8. Processability: PTFE material has good processability and can be processed by molding, extrusion, and compression molding. In addition, PTFE can also be filled with modified, coated, and other methods to enhance its specific properties. This makes PTFE more widely used and meets the needs of different fields.
