               Who is CRT?
 Founded in 1997, CRT (Ceramic Reinforced
  Technologies) discovered the synergistic effect of
  combining Boron Nitride with a Fluoropolymer to
  improve properties.
 To date CRT has concentrated on polymer
  additives,processing aids and lubricants
 In these applications CERFLON® additives have
  consistently outperformed existing additives.
     What is CERFLON®?
 Cerflon® is a ceramic reinforced fluoropolymer.

 A reinforced fluoropolymer occurs when Boron
  Nitride, which is stronger and tougher, is
  introduced into the matrix of a fluoropolymer
  thereby “reinforcing” the polymer.

 This additive benefit significantly increases the
  durability or wear properties in both fluoropolymer
  films and coatings.

 The increase in durability / longevity also provides
  a longer lasting lubrication benefit.
CRT’s Patented Technology
 Demonstrates the synergistic effect of combining Boron
 Nitride with a Fluoropolymer to improve properties.

What a manufacturer said
 when asked why they
   chose CERFLON®
“Next-generation CERFLON® technology
was chosen for this advanced product
because of its superior corrosion
protection, lubricity and anti-wear
properties. Nothing we have seen comes
close to Cerflon performance.”

Falex Tester Set-up
                Falex Test
 This is one of the most recognized ASTM test
  methods to determine the lubrication ability of
  products. It allows you to test lubricants to a
  point of failure.
 Common measurements from this test are:
   Coefficient of Friction
   Maximum pressure (load) until failure

      Shell Four-Ball Test
An ASTM standard that determines lubrication
ability of fluids

Typical measurements allow one to focus not only
on lubrication but the durability of the lubricant

Typical results expressed as wear resistance (scar)
and extreme pressure ( lubricating ability)

COF of Emralon 334 is 0.087. COF of Cerflon is 0.079. The
improved COF is probably due to the gloss being higher. Emralon
334 had a “Gloss 60” of 3.0 while Cerflon had a “Gloss 60” of 5.3
on a 10 scale
