What is Radel PPSU?

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. FDA compliant grades of PPSU are available.

Who makes Radel plastic?

Solvay’s
Radel WM (PPSU) Westlake’s Radel® WM stock shapes are made exclusively from Solvay’s Radel® polyphenylsulfone (PPSU). Its regulatory compliance profile, and lot traceability make it ideal for use in medical and life science applications.

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 transparent?

Radel® PPSU resins are designed to meet a wide range of performance, price and processing requirements. They are available in transparent and opaque colors that help component manufacturers enhance product design and branding opportunities.

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 better than PP?

PPSU (polyphenylsulfone) is the highest performing thermoplastic that gives better durability and heat tolerance than PP and PES. Not only can it withstand continuous exposure to heat and have extreme capability to absorb impact, PPSU plastic does not absorb odor or color. It is naturally BPA free.

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.

What is the difference between PP and PPSU?

PP stands for polypropylene. Bottles made from PP are light in weight, slightly opaque in colour and intended for low to regular use. PPSU stands for polyphenylsulfone. It is a medical grade plastic that is naturally honey toned and quite hard wearing.

What is PPSU plastic used for?

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 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.
