PVDF Granule

PVDF granule, also known as polyvinylidene fluoride particles, are a thermoplastic fluororesin material with excellent properties. Below is a brief description of them:

Appearance and Physical Properties

Appearance: PVDF particles typically appear as translucent or white powders or granular forms.

Physical Properties: Their molecular chains are tightly arranged with strong hydrogen bonds, which gives the material outstanding stability and durability. PVDF particles have an oxygen index of up to 46%, indicating that they are not easily flammable; their crystallinity ranges from 65% to 78%, with a density of 1.77 to 1.80 g/cm³, a melting point of 172°C, a heat distortion temperature between 112°C and 145°C, and a long-term use temperature range of -40°C to 150°C.

Chemical and Performance Characteristics

Chemical Resistance: PVDF particles exhibit excellent chemical corrosion resistance, capable of resisting the erosion of various chemicals.

High Temperature Resistance: They have good high-temperature stability and are suitable for applications in high-temperature environments.

Electrical Insulation: PVDF particles also possess excellent electrical insulation properties, meeting the needs of specific fields for insulating materials.

Mechanical Strength: The material has high mechanical strength and good toughness, capable of withstanding significant mechanical stress.

Applications

Due to their unique properties, PVDF particles are widely used in multiple fields:

Petrochemical Industry: Used to manufacture components for fluid handling systems such as pumps, valves, and pipes, as well as lining materials for storage tanks and heat exchangers.

Electronics and Electrical Industry: In the semiconductor industry, they are used for the storage and transportation of high-purity chemicals; in lithium secondary batteries, PVDF resin is used to make porous membranes, gels, separators, and other applications.

Fluorocarbon Coatings: As one of the main raw materials for fluorocarbon coatings, PVDF coatings are widely used for the protection of outdoor facilities such as power stations, airports, highways, and high-rise buildings.

Other Fields: They are also applied in medical devices (such as artificial lungs, kidneys, and other artificial organs), automobile manufacturing (such as sealing gaskets and other components), architectural decoration (such as exterior wall installations, translucent parts, etc.), and telecommunications and electrical industries (such as converters, coaxial connectors, etc.) among many other industries.

In summary, PVDF particles play an important role in modern industry due to their unique physicochemical properties and wide range of applications.
