PTFE powder About

Product introduction

Polytetrafluoroethylene (PTFE), commonly known as the king of plastics, is a polymer compound formed by the polymerization of tetrafluoroethylene. Insulation and good resistance to aging. Used as engineering plastics, can be made into PTFE tube, rod, tape, plate, film, etc. Generally used in corrosion-resistant pipes, containers, pumps, valves, radars, high-frequency communication equipment, and radio equipment with high performance requirements.

It is made of PTFE resin as the main base material and combined with high temperature resistant resin. It needs high temperature baking to form a film.

FAQ's of PTFE powder:

Q: How should PTFE powder be stored to maintain its quality?

A: PTFE powder should be kept in a cool, dry area, away from direct sunlight. Proper storage in its original 25 kg HDPE drum or bag ensures its 2-year shelf life and helps prevent moisture absorption and contamination.

Q: What benefits does PTFE powder offer when used as an additive?

A: When added to plastics, rubber, lubricants, paints, or coatings, PTFE powder imparts high chemical resistance, low friction, excellent thermal stability, and enhances the durability and lifespan of the final products.

Q: Where is industrial-grade PTFE powder commonly used?

A: Industrial-grade PTFE powder is frequently used in manufacturing processes for plastics, elastomers, lubricants, paint formulations, and coating systems where superior non-stick and wear-resistant properties are required.

Q: What is the recommended process for incorporating PTFE powder into formulations?

A: PTFE powder should be gradually dispersed into the base material under controlled conditions to ensure uniform distribution, preventing agglomeration and optimizing its performance as an additive.

Q: When can users expect optimal performance from PTFE powder?

A: The product achieves optimal performance when used within its two-year shelf life, under suitable processing conditions, and in environments not exceeding its maximum continuous operating temperature of 260C.

Q: How does the particle size of 0.2-10 m affect PTFE powder applications?

A: This fine particle size range provides improved blendability, leading to better integration with other materials and ensuring smooth, uniform textures in final products.
