What is high polymer plastic?

High performance polymer is a group of polymer materials that are known to retain its desirable mechanical, thermal, and chemical properties when subjected to harsh environment such as high temperature, high pressure, and corrosive chemicals.

What is a high quality plastic?

3 types of plastic that are considered as safer options among the others are Polyethylene Terephthalate (PET), High-Density Polyethylene (2-HDPE), and Polypropylene (5-PP).

Is polyamide imide expensive?

PAI have good wear and radiation resistance, very good high temperature properties (approaching those of polyimides), inherently low flammability and smoke emission. They have the highest strength of any unreinforced thermoplastic, but are extremely expensive and attacked by alkalis.

Why is PEEK so expensive?

Why is PEEK So Expensive? The price point for PEEK (polyetherketone) often comes as a surprise to clients. While PEEK’s high temperature resistance can make it difficult to process, in its solid state PEEK is readily machinable by CNC milling machines.

What are high polymers?

Definition of high polymer : a substance (such as polystyrene) consisting of molecules that are large multiples of units of low molecular weight.

What is difference between plastic and polymer?

Polymers can exist organically or be created synthetically, and consist of chains of joined individual molecules or monomers. Plastics are a type of polymer composed of chains of polymers which can be partially organic or fully synthetic. Simply put, all plastics are polymers, but not all polymers are plastics.

What is engineering polymers used for?

Engineering polymers are a type of plastic materials that are durable and rugged. Because of these properties, this type of polymer is widely used in the manufacturing industry. It is also commonly used as material in consumer goods too.

Is Pai amorphous?

PAIs are amorphous thermoplastics that offer Tgs around 275 °C toughness, high continuous use temperatures, inherent flame resistance, high modulus, and very high strength. PAIs contain amide groups and hence will absorb moisture and can affect dimensional stability.

What is polyamide imide used for?

Polyamide-imides are used extensively as wire coatings in making magnet wire. They are prepared from isocyanates and TMA (trimellic acid-anhydride) in N-methyl-2-pyrrolidone (NMP). A prominent distributor of polyamide-imides is Solvay Specialty Polymers, which uses the trademark Torlon.

How expensive is PEEK plastic?

Interest among plastics processors in polyetheretherketone (PEEK), an engineering thermoplastic that offers a mighty array of mechanical properties including very high heat resistance and strength, is dampened by the material’s price tag, which exceeds $10/lb.

How much is PEEK per pound?

Sources estimate the price of medical-grade PEEK at close to $400 per pound for injection molding material compared to about $44 per pound for industrial-grade PEEK. The price is much higher, above $1,300 per pound, for PEEK supplied as a machinable billet.
