ENGINEERING PLASTICS

Poly­ami­de (PA) or Nylon belongs to the semi-crystal­li­ne ther­mo­plastics. PA is a mate­ri­al with low den­si­ty, a high ther­mal sta­bi­li­ty and an excel­lent wear resistance.

A good coef­fi­ci­en­cy of fric­tion, impact resis­tance, che­mi­cal resis­tance espe­cial­ly against oil makes PA to one of the most important engi­nee­ring thermoplastics.

Typi­cal characteristics:

• good mecha­ni­cal strength
• high impact resistance
• high tough­ness under cold conditions
• good dam­ping behaviour
• good gli­ding behaviour
• good abra­si­on behaviour

App­li­ca­ti­on area: Con­struc­tion and instal­la­ti­on bran­ches (dowels, fas­te­ners, power tools), sani­ta­ry tech­no­lo­gy (hand­les, fit­tings, fans), mecha­ni­cal engi­nee­ring (gears, pul­leys), E&E (swit­ches, electri­cal clamps, coil body, con­nec­tors), auto­mo­ti­ve indus­try (hub­caps, parts under the hood)

PA 6T/6I has very good mecha­ni­cal strength and stiff­ness. The water absorp­ti­on is lower com­pa­red to other poly­ami­des. PA6T/6I is hot water resistant and high che­mi­cal resistant. Fur­ther­mo­re PA6T has a high app­li­ca­ti­on tem­pe­ra­tu­re. The­se cha­rac­te­ris­tics are per­fect for app­li­ca­ti­ons under the hood.

Typi­cal characteristics:

• extre­me­ly low water absorp­ti­on and very good dimen­si­on stability
• excel­lent che­mi­cal resis­tance and wea­the­ring stability
• excel­lent hydro­ly­sis resistance
• lowest den­si­ty of all polyamides
• high impact resis­tance up to – 40°C
• excel­lent wear and tear resis­tance and gli­ding properties
• high bar­ri­er propterties
• easy pro­ces­sing

Advan­ta­ges PA12 com­pa­red to PA6.6

• less hygro­scopic (satu­ra­ti­on at 23 °C/ 50% rela­ti­ve humi­di­ty amounts app. 1%)
• bet­ter impact resistance
• good wea­ther per­for­mance (without spe­cial additives)

The­se cha­rac­te­ris­tics are per­fect for out­door app­li­ca­ti­ons, whe­re exter­nal impacts for examp­le fal­ling rocks are pos­si­ble. The water absorp­ti­on of PA12 is not only lower com­pa­red to PA6.6, it is also much slower. The­se cha­rac­te­ris­tics make PA12 rela­tively insen­si­ti­ve for chan­ging envi­ron­men­tal influ­en­ces, howe­ver, the strength and tough­ness are not as good as PA6 and PA6.6.
