PTFE PVDF Machined Parts

HONYFLUO® PTFE (Polytetrafluoroethylene) is a semi-crystalline fluropolymer thermoplastic. It is commonly referred to as teflon which is a brand name.PTFE is the most widely used fluropolymer in a range of applications. It is known for being highly resistant to chemicals and for its superior thermal stability.

Ptfe Parts Compared to other engineering grade thermoplastics it has poor mechanical properties, though glass and carbon filled grades with improved dimensional stability are available.

Because of its resistance to chemicals, PTFE is commonly used in chemical, food and pharmaceutical engineering.

Polytetrafluoroethylene Part is favoured over PVDF for sliding applications with exposure to extreme chemical stress

The custom machined PTFE part above is having its bottom features rough machined. This is an example of a turn-milled part that is utilizing live milling in addition to CNC turning.

A flanged sleeve bearing machined from Teflon™ PTFE receives a finishing pass.  HONY efficiently machines parts like this by starting with an in-house compression molded PTFE tube in order to minimize material waste and reduce machining time.

HONYFLUO®PTFE (Polytetrafluoroethylene) properties:
1. Non-stickiness: Its friction coefficient is extremely small, only 1/5 of that of Polyethylene, which is an important feature of the perfluorocarbon surface. And due to the extremely low intermolecular force of fluorine-carbon chains, PTFE is non-sticky.
2. Mechanical properties: Tensile strength σb (MPa): 20.7~27.5 Elongation δ5 (%): 250~350 Impact toughness value αk (J/cm2): With notch: ≥16.1; Without notch: >98.1 Tensile Elastic modulus (MPa): ≥3.92 Hardness: 50~65D
3. Thermal properties: Heat distortion temperature: 1.86MPa: 55°C; 0.46MPa: 120°C Martin heat resistance temperature: 250°C Continuous use temperature: 250°C
4. Combustibility: Self-extinguishing PTFE maintains excellent mechanical properties in a wide temperature range of -196 to 260 ° C. One of the characteristics of perfluorocarbon polymers is that they are not brittle at low temperatures.

HONYFLUO®PTFE (Polytetrafluoroethylene)is stable under normal temperature and pressure, avoid humidity, heat and high temperature. No true melting point, slowly decomposes above 450°C, and directly turns into gas. At 327°C, the mechanical strength suddenly disappears. Insoluble in any solvent. In addition to being able to react with molten alkali metals, it is not corroded by any substance, even if it is boiled in hydrofluoric acid, aqua regia, fuming sulfuric acid, or sodium hydroxide, it will not change.

Ptfe Machined Part is a white, odorless, tasteless, non-toxic powder, commonly known as "the king of plastics". It has excellent chemical stability, corrosion resistance, sealing, high lubricity and non-stickiness, electrical insulation and good aging resistance. High temperature resistance, working temperature up to 250°C. Low temperature resistance, good mechanical toughness at low temperature, even if the temperature drops to -196°C, it can maintain 5% elongation. Corrosion-resistant, inert to most chemicals and solvents, resistant to strong acids and alkalis, water and various organic solvents. Good weather resistance, with the best aging life among plastics. High lubrication, the lowest coefficient of friction among solid materials. Non-adhesive, it is the one with the smallest surface tension among solid materials, and does not adhere to any substance. It is non-toxic, physiologically inert, and has no adverse reactions after long-term implantation in the body as artificial blood vessels and organs.
