The other day contacted me a customer to tell me that he had found the same product that we produce but with a noticeable difference in price.
At first glance, it may seem the same product, but if we look at the technical characteristics and what material are made both, it is when we realize that, as in people, you have to look beyond the forms.
While one is made of “conventional” plastic, ours is made of Radel® PPSU
Here is a comparison of Radel® R with normal Polypenysulfone and Ultem®:
What does PPSU mean?
PPSU is the acronym for Polyphenyl sulfone. Also known as PPSF, PPSU is part of Sulfone polymers, which are high-performance polymer exhibiting very attractive properties such as high-temperature performance, good chemical resistance, outstanding toughness, excellent colorability and very good dimensional stability. As the other sulfone polymers, PPSU is an amorphous polymer and displays, therefore good creep resistance, isotropic thermal and mechanical properties (if non-reinforced) and transparency properties. PPSU is used in various applications including plumbing, food services, medical, aerospace, wire & cable, etc.
High heat, high-impact performance
Radel® polyphenyl sulfone (PPSU) delivers the highest performance, offering better impact resistance and chemical resistance than polysulfone (PSU) and polyetherimide (PEI).
Toughness and Impact Strength
Radel® polyphenyl sulfone (PPSU) can withstand continuous exposure to moisture and high temperatures and still absorb tremendous impact without cracking or breaking.
The impact strength of test plaques heat’s aged at 190 ° C (375 ° F) for 170 hours was evaluated using a Gardner falling dart impact tester. Radel® PPSU absorbs significantly higher impact force than polyetherimide (PEI) without cracking or breaking.
