Fluoropolymer Parts


Alfa Chemistry Fluoropolymers provides customers with a variety of fluoropolymer parts to help you solve problems such as sealing and insulation.

Sealing solutions

  • Fluoropolymer O-rings are used as standard sealing solutions in harsh and hot environments to optimize costs and ensure long life cycle performance, providing the ultimate sealing performance, reliability and safety for various industrial sealing applications.
  • For the most demanding areas, such as fuel sealing systems, fluoroelastomer O-rings are the first choice for durable parts that can withstand high temperatures and today's corrosive automotive and aircraft fluids. O-rings have many applications in automotive and aerospace systems.

Insulation solutions

With the development of science and technology, especially the development of military industry, aerospace, aviation, communications, etc., higher requirements are put forward on wires and cables. In fact, higher requirements are put forward on conductors and insulating materials. The performance requirements are mainly manifested in the following aspects.

  • High operating temperature
  • It should not be limited to several tens of degrees such as PE, PVC, ordinary rubber, and insulating paper, but it is required to reach 100 °C, 150 °C, 200 °C, 250 °C, or even higher.

  • High frequency
  • It can't just be satisfied with the power frequency and carrier frequency, but require high frequency and frequency, up to decimeter wave, millimeter wave, and even 40G, 60G.

  • Environment resistant
  • It can withstand various harsh environments, such as high and low temperatures, various weather conditions, and radiation resistance. 

  • High flame retardant
  • Effectively improve the safety factor. 

  • Anti-aging
  • Long service life and high reliability.

  • Resistant to media
  • Can withstand various harsh media. 

  • Miniaturization
  • Miniaturization, light weight, less space, and weight reduction are particularly important in aerospace.

The reason why fluoroplastic insulated wires and cables is called one of the most important and most extensive application fields of fluorine plastics is precisely because fluorine-containing plastics meet the above requirements in different aspects and to varying degrees.

Fluoropolymers are very good insulating materials, especially suitable for application environments where failure costs are high. Table 1 lists the advantages and disadvantages of fluoropolymers.

Aiming at the problem of insufficient anti-wear and anti-breakdown capabilities of fluoropolymers, specialized technologies have been developed to engineer fluoropolymers to make them more capable of coping with environmental and chemical challenges. For cables used in strict environments, the consequences of their failure will be very serious. Therefore, it is important to ensure the integrity of the electrical and mechanical properties of the cable during its service life.
