Teflon is a polymer of teflon. The abbreviation is PTFE. The infrastructure of Teflon is. - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 -. Teflon is widely used in a variety of needs anti-acid and organic solvents, it is not toxic to humans, but one of the raw materials used in the production process, ammonium perfluorooctanoic acid (PFOA) is considered to be carcinogenic.

Use: can be made into rods, plates, pipes, films and a variety of special-shaped finished products, used in aerospace, chemical, electronics, machinery, medicine and other fields.

It does not melt at temperatures of 250 degrees C and does not firm at ultra-high temperatures of -260 degrees C. Teflon lubrication is different, even ice is better than it;

Highly chemical stability and excellent resistance to chemical corrosion, such as strong acid, strong alkali, strong oxidants, etc. , has outstanding heat, cold and motorcycle resistance, permanent application temperature category of -200 -250 degrees C, as well as excellent electrical insulation, and not affected by temperature and frequency. In addition, with no soiling, no water absorption, no incineration and other characteristics. Suspended resin generally using molding, sintering measures molding processing, the resulting rods, plates or other profiles can also be further used with carplowing, drilling, milling and other machining methods. The rod can then be turned into a directional film.

Electrical performance: Teflon has very low dielectric and dielectric losses at a wide frequency scale, and the breakdown voltage, volume resistivity and arc resistance are high.

Self-lubricity: With a small coefficient of friction in plastic, it is a fanciful oil-free smooth material.

In PTFE, F atoms mask the C-C key and the C-F bond can be high and stable, except alkali metal and element fluorine it is not any chemical.

聚四氟乙烯的基本常识

    聚四氟乙烯是四氟乙烯的聚合物。英文缩写为PTFE。聚四氟乙烯的基础结构为. - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 -. 聚四氟乙烯广泛利用于各种需要抗酸碱和有机溶剂的,它自身对人没有 毒性，然而在生产过程当中使用的原料之一全氟辛酸铵(PFOA)被以为可能具有致癌感化。

 　用 途： 可制成棒、板、管材、薄膜及各种异型成品，用于航天、化工、电子、机械、医药等领域。

它在250℃的温度下不融化，在-260℃的超高温中不发坚。聚四氟乙烯润滑异样，连冰都比不外它;它绝缘性能特殊好，厚的一层薄膜，便足以招架1500V的高压电。

具有高度的化学稳固性和出色的耐化学腐蚀才能，如耐强酸、强碱、强氧化剂等，有突出的耐热、耐冷及耐摩性，恒久应用温度范畴为-200-+250℃，还有优良的电绝缘性，且不受温度与频率的影响。另外，具有不沾着、不吸水、不焚烧等特色。悬浮树脂一般采用模压，烧结的措施成型加工，所制得的棒、板或其他型材还可进一步用车刨、钻、铣等机加工方式加工。棒材再经车削牵伸可制成定向薄膜。

电性能：聚四氟乙烯在较宽频率规模内的介电和介电损耗都很低，而且击穿电压、体积电阻率和耐电弧性都较高。

自润滑性：拥有塑料中较小的摩擦系数，是幻想的无油光滑材料。

PTFE中F原子把C-C键遮蔽起来并且C-F键键能高特别稳定，除碱金属与元素氟外它不被任何化学药品。
