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.
What mean of PPSU bottle?
polyphenylsulfone
PPSU stands for polyphenylsulfone. It is a medical grade plastic that is naturally honey toned and quite hard wearing. Intended for higher use.
Is PPSU safe?
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).
What is Polyketone used for?
Polyketone is used for technical components in mechanical engineering and in the automotive industry, e.g. as a fuel line. The material is also used in the electronic/electrical industry, for example in housings or switches.
How is Polyphenylsulfone 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.
What is PPSU plastic used for?
PPSU is often an excellent choice for components that are exposed to high temperatures and corrosive media because it has exceptional chemical resistance. Examples include pipe fittings, battery containers, medical device parts, and sterilizable products for health care and nursing.
Is PPSU safer than PP?
PPSU (polyphenylsulfone) is a high performing thermoplastic that is more durable and heat-resistant than PP and PES. Due to its even higher melting point than PES, PPSU plastics are commonly used in medical devices requiring repeated sterilization.
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.
What is Pok plastic?
Polyketone is a semi-crystalline polymer that combines: the higher heat performance of polyamide 6 and 6/6, the fuel resistance of nylon 11 and 12, the low moisture absorption of PBT, and the exceptional wear & friction performance of POM.
How do you make Polyketone?
To make polyketones, you take ethylene gas and carbon monoxide, and react them with a palladium(II) catalyst: Ethylene is dirt cheap; it’s the monomer for polyethylene. Carbon monoxide is dirt cheap, too. You make carbon monoxide every time you burn wood, or a candle, or just about anything containing carbon.
Who manufactures Radel?

What’s the difference between propylene glycol and ethylene gliescol?
Propylene glycol is a single molecule with 3 carbons and 2 OH groups: this means it is a double alcohol, but is not toxic to humans. Ethylene glycol has 2 carbons and 2 OH groups: it is metabolized to TOXIC oxalic acid, wherein each carbon is oxidized and it becomes…
Can you use polyethylene glycol in polyesters?
Best Answer. In brief: NO! Polyethylene glycol is found in polyesters, but propylene glycol is an organic alcohol found in some cosmetics. Polyethylene glycol is found in polyesters, but propylene glycol is an organic alcohol found in some cosmetics.
Why is polyethylene glycol used in antifreeze?
Polyethylene glycol is, in fact, used in antifreeze because it lowers the freezing temperature of water. It produces ethylene glycol when processed. Ethylene Glycol has been known to be lethal in doses as low as 786 mg/kg.
Are there any electronic cigarettes that contain polyethylene glycol?
Even the electronic cigarettes that DO utilize polyethylene glycol (PEG) come nowhere near this mark. Laboratory studies on the inhalation of vaporized/aerosolized PEG all showed that inahlation did not, in fact, deliver lethal, or even harmful, doses of PEG to laboratory animals.
