What is Radel plastic?

High temperature thermoplastic material with outstanding impact resistance that is autoclavable. PPSU (polyphenylsulfone) (Radel® R) is a high temperature thermoplastic material with outstanding impact resistance. Radel® R is resistant to hot water and steam and can withstand repeated cycles in a steam autoclave.

Who manufactures Radel?

Solvay S.A
Radel® R-7000 is a registered trademark of Solvay S.A.

What is PPSU material?

Polyphenylsulfone (PPSU) is a new material for the production of baby bottles. PPSU is a polyether plastic formally composed of bisphenol S (BPS) and 4,4′-dihydroxybiphenyl (DHBP), which both have slight endocrine activities in in vitro tests.

Is PPSU radiolucent?

It can also withstand up to 1000 autoclave cycles without warping, effectively maintaining its toughness and impact resistance. Furthermore, the PPSU is radiolucent, enabling x-ray use, and features a heat-distortion temperature of 207°C as well.

Is PPSU safe for babies?

The polyphenylsulfone (PPSU) meets Zoom T’s strict requirements for its curved baby bottles that are safe and easy to handle. Ultrason® P 3010 is approved for food contact and features excellent strength, chemical resistance and resistance to superheated steam up to 180°C (356°F).

Is PPSU FDA approved?

Food Applications: Many PPSU grades are FDA-approved, which is why they are used for making microwave safe popcorn makers and dishes.

How is PPSU made?

PPSU material (chemically known as polyphenylsulfone) is manufactured by Ensinger in standard stock shapes for machining, and is most often extruded in sheet and rod using Radel® PPSU polymer. PPSU plastic is an amorphous material, which has a high glass transition temperature and low moisture absorption.

Is PPSU plastic safe?

PES (polyethersulphone) is a tougher and safer plastic than PP as it comes from a family of thermoplastic polymers – meaning it can withstand temperatures as high as 180°C without chemically breaking down.

Is PPSU toxic?

PPSU is a medical-grade plastic that’s naturally honey-toned and incredibly hard-wearing. Again, it’s a very safe plastic and is the ‘gold standard’ when it comes to baby bottles. PPSU is lightweight and temperature resistant up to 180 degrees celsius without any deformation or release of toxic substances.

Can plastic show up on xray?

In answer to the often asked question, “Can you see plastic on x-ray?”, the answer is that engineering plastics do not show up well on x-ray or fluoroscopic displays, unless they have been modified in some way to make them more opaque than the surrounding substrate.

What plastic is used for medical devices?

Common thermoplastic materials used in the manufacturing of medical plastic products include polycarbonate, polypropylene, polyethylene, or the formulation of custom polymers to meet specific medical device applications.

Is Ppsu amorphous or crystalline?

PPSU, PESU, PSU and PEI are good examples of amorphous thermoplastics offering these qualities. Semi-crystalline thermoplastics have a highly ordered molecular structure with both crystalline and amorphous regions. Due to the presence of crystals, they are generally opaque and have sharp melting points.
