What are types of fillers and their advantages?

 PTFE with Glass Fillers: Glass is the most widely used filler in PTFE. Glass fillers enhance the strength and durability of PTFE. The more the glass filler amount the better the compressive strength of PTFE. If glass-filled PTFE is inert gas sintered the porosity and the tendency to creep will reduce more. Due to its high wear resistance, it is used in hydraulic piston rings.


PTFE with Molybdenum Disulfide Fillers: Molybdenum Disulfide or MoS2 becomes more solid as well as smooth when combined with bronze or glass. This filler also improves the wear resistance and compressive strength of PTFE. It is used in dynamic seals. It also lowers the coefficient of friction.


PTFE with Carbon Fillers: The electrical conductivity of carbon makes it static dissipative. This conductivity of carbon also makes it applicable for appliances needing higher thermal conductivity. It is less corrosive than glass. It can be used either in the form of powder or fiber. The benefits of carbon-filled PTFE are reduced deformation under heavy load, better compressive strength, low permeability, and improved wear resistance.


PTFE with Bronze Fillers: Bronze, as a filler material, reduces the chemical inertness and non-stick properties of the PTFE. Bronze fillers improve the wear resistance of PTFE. These fillers are useful for applications requiring good electrical and thermal conductivity. Bearing and piston ring applications use materials having 55% bronze.


PTFE with Stainless Steel Fillers: Stainless steel fillers should be implemented in applications employing steam and hot liquids at high temperatures. PTFE with powdered stainless steel fillers can bear heavy loads. This filler is useful for food, drink, and mechanical industries.


PTFE with Graphite Fillers: Graphite has self-lubricating properties which reduce friction. It is generally used in combination with glass or carbon or both. It has good wear resistance due to its flaky form.


PTFE with Polymide Fillers: It has a lower friction coefficient. It is good for stainless steel, plastic, brass, and aluminum surfaces as it corrodes slowly. Polymide is a synthetic polymer. Stop-start and dry running or non-lubricated applications can use PTFE with polyamide fillers.

Upgrade Your Seals: A Guide to FEP Encapsulated O-Rings and Their Applications

Image
  In harsh environments where reliable sealing is needed, FEP encapsulated O rings are found to be widely used by engineers and designers for their excellent performances. These innovative rings have combined the strengths of FEP (fluorinated ethylene propylene) like chemical resistance with those of an elastomeric core such as its ability to create a sealable bond at the interface between two surfaces which are inherently not compatible in nature. Sealmax, a reputable company that offers high-performance sealing solutions, explores  a guide to FEP Encapsulated O rings and applications in this blog post. FEP (Fluorinated Ethylene Propylene): This is a thermoplastic material that possesses properties similar to those of PTFE. Elastomeric Core: The major part of the O ring, usually made from flexible materials like FPM (fluorocarbon rubber) or VMQ (silicone), allowing for elasticity in order to achieve superior sealing. Seamless FEP Coating: A super-thin protective laye...

Do You Know the Benefits of Structured Expanded PTFE with Fillers?

Image
  What is Expanded PTFE? Expanded PTFE is created using only pure PTFE. An adhesive is expanded PTFE . It has greater cold flow and creep resistance. It is used to seal pipelines, hydraulic systems, and pneumatic systems. Expanded PTFE is air-permeable due to its microporous nature. It is a non-toxic, chemically resistant substance. It can operate at temperatures up to 260°C. Expanded PTFE has excellent UV resistance and radial expansion properties. What is Filled PTFE? Although PTFE is a material that is frequently used, it must be modified to improve its performance for various industrial applications. It can be combined with other substances to lessen its limitations and increase its productivity in specialised and fiercely competitive fields. They increase PTFE's strength. PTFE typically contains fillers including glass fibre, zinc oxide, charcoal, bronze, copper, graphite, and molybdenum disulfide. Different fillers have various characteristics that make them suitable fo...

What are Gaskets and Types of Gaskets?

  Gaskets are used as a sealant to fill irregularities or gaps between two or more surfaces. Gasket manufacturers offer different types of gaskets such as   PTFE envelope gasket , kammprofile gasket and so on. Due to the safety issues concerning usage of asbestos in gaskets, reputed manufacturers offer gaskets made using non-asbestos gasket sheets. Being a major component for diverse industrial applications, gaskets have to be chosen carefully. If you are someone from the food processing industry looking for a gasket, then  silicone gasket manufacturer  who specialise in food grade silicone gaskets might be able to help you. But a different type of gasket would be needed in a petrochemical plant. Gaskets are mostly chosen based on the properties such as chemical resistance, temperature resistance, pressure resistance, compression etc. Every standard gasket comes with its own set of properties. However, gasket properties can be enhanced with a combination of various m...
