Characteristics of PFA particles:

1. Excellent plasticity:PFA GranulesWith the excellent characteristics of PTFE, its mechanical strength is higherFEP. At the same time, they are also fluorocarbon polymers having excellent melt fluidity. The resin can be directly processed by ordinary thermoplastic molding methods.

2. Excellent corrosion resistance: most chemicals will not damagePFA Granules. Its chemical resistance is similarPTFE, and is superior to vinylidene fluoride.

3. In a large temperature range, it can maintain its mechanical strength: from extremely low to extremely high temperature, PFAThe particles can maintain their flexibility without reducing their toughness, andPFA GranulesThe high temperature that can be used continuously is 260 ℃,PTFE Likewise, this is the ultra-high continuous service temperature of all fluorocarbon polymers.

4. Excellent electrical properties: In a wide frequency range, the dielectric constant is low and stable. The insulation loss coefficient is very low and stable over a wide temperature and frequency range. High volume resistivity. Very high insulation breakdown strength.

5. Non-combustible: PFABoth PTFE and FEP are non-flammable polymers. The limiting oxygen index is greater than 95%, and the fire rating is UL94 V0.

6. Good weather resistance: even if exposed to wind and rain for a long time, PFAThe unique properties will not change.

7. Non-stick, low friction:PFA GranulesIt is non-sticky, has the ability to resist water, oil and other substances, and has a smooth surface. It is widely used in the semiconductor industry as well as medical, chemical anti-corrosion, automotive and other fields.

Properties of PFA granular materials:

1. It is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. Compared with PTFE, the melt adhesion is enhanced, the melt viscosity is reduced, and the performance is unchanged. The resin can be directly processed into products by conventional thermoplastic molding methods.

2. Long-term use temperature, excellent chemical resistance, corrosion resistance to all chemicals, low friction coefficient in plastics and good electrical properties. Its electrical insulation is not affected by temperature. Called"The Plastic King”。

3. Its chemical resistance is similar to polytetrafluoroethylene and better than vinylidene fluoride.

4. The creep resistance and compressive strength are better than PTFE, the tensile strength is high, and the elongation can reach%. Good dielectric properties and excellent radiation resistance.

5. Non-toxic: with physiological inertia, can be implanted into the human body.
