Poliamid

A polyamide is a macromolecule with repeating units linked by amide bonds. Polyamides occur both naturally and artificially. Examples of naturally occurring polyamides are proteins, such as wool and silk.

Amide groups have the general chemical formula CO-NH. The name nylons refers to the group of plastics known as polyamides.

The most famous form of polyamide fabric is nylon, but there are quite a few different varieties of this textile.

Poliamid ele sunt polimeri formați din mai mulți monomeri de amide, unite prin legături peptidice într-o reacție de policondensare.

Aceste legături se pot forma pe cale naturală, ca în cazul proteinelor, lânii sau a mătăsii, sau se pot fabrica prin procesul de polimerizare ca de exemplu în cazul nailonului. Aramid byl vyvinut především jako vlákno odolné proti vysokým teplotám. Takzvané meta-aramidy (m-aramidy) mají bod tání přes 400° C, jsou odolné proti mnoha chemikáliím, pružné, snadno se zpracují v textilní výrobě.

But, choosing the right type of synthetic fabric can help you get the maximum from an article. It also can be molded about degrees F (degrees C) lower with less mold shrinkage because it is slightly less crystalline. PA material, polyamide or commonly called nylon, is manufactured by Ensinger in standard stock shapes for machining in sheet, rod and tube. There are often numbers associated with nylon plastics types such as 6 and 46.

Nylon or polycaprolactam is a polymer developed by Paul Schlack at IG Farben to reproduce the properties of nylon ,without violating the patent on its production. Around the same time, Kohei Hoshino at Toray also succeeded in synthesizing nylon 6. It is a semicrystalline polyamide. INDUSTRIJSKA PLASTIKA – POLIAMID 6. Poliamid je kao industrijska plastika vrlo zbijene snage poznat po svojoj otpornosti na visoke temperature i rastezljivost. To je najtvrđi i najkrući oblik exstrudiranog POLIAMID -a.

Glavne karakteristike su visoka otpornost na goriva, ulja, masti, većinu organskih kiselina i lužina. Aliphatic polyamides such as Nylon and Nylon are widely used for engineering and industrial applications. The unreinforced grades have an upper temperature for continuous use of around 3- 3K, and the glass and mineral reinforced grades of about 3- 3K.

Applications include almost every industry and market. Both synthetic fibres are very tear-proof and abrasion-resistant and absorb little moisture (thus good transport of moisture away from the body) and are stretchy, crease-free, but also prone to pilling. Polyester has excellent return conduct. Because of how polyamide fabrics behave in regards to moisture and abrasions, nylon has considerable resistance against both. It absorbs very little moisture overall and it is also quite durable to abrasions and damage from oils and several other chemicals.

Aromatic polyamide fiber are highly crystalline fibers in which at least of the amide linkages (−CO–NH−) are attached directly to two aromatic rings, and have the lowest density and the highest tensile strength-to-weight ratio among the current high performance fibers. No matter how complex your designs, polyamide is a great and versatile choice. The self-supporting powder needs no support structure and works equally well for fully functional prototypes or end-use parts.
