- Also polycarbonates, which are commonly known by the trademark name Lexan, are a type of thermoplastic polymer, which, due to their durability, are widely used in bullet-resistant ‘glass’. The softest forms of plastic can be runny such as polymer clays, which are very malleable and can also include liquid forms.

What Is Tyvek? Features. Tyvek has a number of features that make it ideal for the applications for which it is used. For one, it is a lightweight material that makes it great for use in envelopes and packaging, because it's easier to ship and move.It is slightly thin, allowing water vapor to pass through it, but not liquid water.he demand for synthetic materials that have very specific features is high, because of their ability to find their way into various applications. One such material is Tyvek, which is a brand of high-density fibers that have been flashspun and offer a high tensile strength while able to filter out small gas particles.

Polyvinyl fluoride Polyvinyl fluoride (PVF) or –(CH 2 CHF) n – is a polymer material mainly used in the flammability-lowering coatings of airplane interiors and photovoltaic module backsheets.It is also used in raincoats and metal sheeting.Polyvinyl fluoride is a thermoplastic fluoropolymer with the repeating vinyl fluoride unit: It is structurally very similar to polyvinyl chloride. PVF has low permeability for vapors, burns very slowly, and has excellent resistance to weathering and staining.It is also resistant to most chemicals, except ketones and esters. It is available as a film in a variety of colors, and formulations for various end uses, and as a resin for specialty coatings.t is also used in raincoats and metal sheeting.

- Wood, hair and rubber are natural polymers, but scientists have imitated these natural polymers in synthetic polymers that have many uses in the modern world. Synthetic polymers were first used as a water clarifier in 1945, but it wasn't until about 1970 that they were first introduced in the pool industry. The key to understanding why they work as a water clarifier is that each link in the polymeric chain takes on an electrical charge.
