What plastic is useful in cryogenic temperatures?

The PCTFE is one of the best material in valve and seals in cryogenic temperature as this material has low gas permeability, chemical stability and resist at temperature below -200°C. Our company provides to most of the european cryogenic industrial companies in seal and gaskets.

Is Lexan a thermoplastic?

Lexan is a brand name and not the name of the material itself, polycarbonate resin thermoplastic is what it’s more commonly referred to as. In a nutshell, Lexan is that it’s a solid substance that can deform in extreme heat is exhibit excellent toughness, high impact strength, and a high modulus of elasticity.

What makes polycarbonate strong?

What Makes Polycarbonate So Strong? The source of polycarbonate’s strength is its incredibly strong chemical structure. Its molecules possess tremendously strong bonds in high numbers, giving it its unique levels of resistance.

What thickness of Lexan is bulletproof?

Not only must the ballistic glass be thicker–at least 1.625-inches thick, if not 1.75–it also needs to be of an entirely different composition. The only bullet resistant glass that’s going to stop a .

Does Lexan scratch easily?

It is highly resistant to acids and chemicals, such as gasoline. It has a low level of flammability, which is essential in certain industries. LEXAN polycarbonate is also available in a variety of flexible (film) grades. The cons of LEXAN are that it is easier to scratch, and minor scratches cannot be polished away.

Is polycarbonate a stab proof?

Pros of Bullet Resistant Polycarbonate Bullet resistant polycarbonate is one of the thinnest ballistic protection options available. Laminated polycarbonate systems can meet UL level 1 bullet resistance at just ¾”. Because of that softness, it can actually catch a bullet within the sheet.

What do you need to know about liquid nitrogen?

MATERIAL SAFETY DATA SHEET – “LIQUID NITROGEN”. ROC Group of Companies Page 2 of 6 INGREDIENT NAME: Nitrogen PERCENTAGE >99% CAS NUMBER 7727-37-9. 4. FIRST AID MEASURES. FIRST AID PROCEDURES: INHALATION: Persons suffering from lack of oxygen should be removed to fresh air. If victim is not breathing, give artificial respiration.

What kind of material is Lexan used for?

Lexan® is a common polycarbonate material chosen for containment in the zero-g environment. It is a tough material with excellent optics, and it provides a very good solution for the majority of experiments. Another brand name polycarbonate that has been used successfully is Makrolon®.

How big is a Lexan sheet of plastic?

GE Plastics: Lexan 9034 (form: 5.5 mm (0.22 inch) thick sheet) The relationship of joint strength of solvent-welded joints of polycarbonate to their microstructure was investigated.

Why is the expansion ratio of liquid nitrogen important?

Violent reactions, e.g. rapid combustions or explosion, may occur if the materials which make contact with the oxygen are combustible. Because of the large expansion ratio of liquid to gas (1:696), it is important to provide adequate ventilation in areas using liquid nitrogen.
