Polyester, PET, PBT For Dummies. AKA, For The Beginner

 

**Why use PTFE:

  •  Very Slippery and Non-Stick
  • Wear Resistance
  • 500ºF Continuous Use Temperature
  • Excellent Chemical Resistance
  • Very Easy To Machine and Fabricate

 


Polyester, PET, PBT For Experts

 

***

This materials is…

excellent wear resistant, heat resistant and non-stick. PTFE is a thermoplastic polymer, which is a white solid at room temperature, and a density of about 2.2g/cm3. Material has extremely good chemical resistance. Retains properties over a large range of temperatures,  -100ºF to 400ºF.

  • Chemically Resistant to Most Chemicals and  Caustic/Acidic Cleaning Agents
  • Offers excellent strength, rigidity and machinability
  • Excellent Electrical and Thermal Insulation
  • Available in Wide Range Of Grades and Fillers

This material is used frequently as a bearing or non-stick surface. Excellent choice for caustic fluid handling valves and fittings. Massive size range in molded rod, tubular bar, and plate. PTFE is also known as: Fluon®, Neoflon®, Polyfon®, Chemfluor®, and more.
