High purity raw materials have a wide range of applications in the advanced fields of all industries, and different purity levels correspond to different application fields. Semiconductor has very high requirements for raw materials. Fluorinated plastic products are widely used in the semiconductor industry. One of its characteristics is ultra-clean and high purity, which ensures the quality of semiconductor manufacturing and production.

At present, the high purity raw materials used in fluorine plastic products are DAIKIN and Dupont. This paper mainly explains its PFA series of raw materials.

This paper mainly explains the AP-211SH, AP-230SH, AP-231SH and 451HP and 951HP Plus of DuPont.

These models are also used in PFA pipe fittings, joints and other high-purity products produced by Warinkner.

How to judge the stability and purity of the raw material?

Here are several important attributes to determine the stability and purity of the raw material:

① Melt Flow Rate (MFR)

Moidity is crucial to plastic processing, so how to reflect the thermal fluidity of plastic? The international common method is to use the "melt flow rate".

The size of the melting rate is closely related to the molecular weight of the plastic materials. The higher the molecular weight, the higher the viscosity of the melt, the worse the flowability, the lower the melting rate; the lower the molecular weight, the lower the melt viscosity, the better the liquidity, and the greater the melting rate.

The plastic materials with large melting rate are suitable for high-speed processing processes such as injection molding and extrusion, which can obtain better molding effect and surface quality, while the plastic materials with small melting rate are suitable for low-speed processing processes such as blow molding and calendering, which can obtain better tensile performance and transparency.

② Melting point (Melting Point)

The melting point of a substance is closely related to its chemical properties, molecular structure, crystal structure, molecular weight, solvent and temperature.

Generally, the higher the melting point, the higher the crystallinity of the substance; the lower the melting point, the less the intermolecular attraction of the substance, and the easier to mix with other substances. Substances with low melting points are often more prone to oxidation and corrosion, and can become more unstable at high temperatures.

③ Specific gravity (Specific Gravity)

The larger the proportion, the greater its density, the greater its strength, and the better the heat resistance.

④ Tensile Strength (Tensile Strength)

Tensile strength: the maximum tensile force that a material can withstand when it is pulled, usually used to measure the strength and durability of a material.

⑤ Ultimate elongation rate (Ultimate Elongation)

In the stress-strain curves of the material, the ultimate elongation usually corresponds to the fracture point of the material. When the material is subjected to a large enough tensile force, it will undergo plastic deformation until it eventually breaks. The higher the ultimate elongation, the better the material is, that is, it can withstand more deformation without breaking.
