ROTEC® HPPA – A NEW HIGH PERFORMANCE METAL REPLACEMENT
25.04.2022
After successful introduction of ROMITRON® PPS, ROMIRA now offers ROTEC® HPPA as a new high performance product for metal replacement. While ROMITRON® PPS takes ROMIRA to the top of polymer pyramid from heat resistance point of view, the newly developed ROTEC® HPPA positions ROMIRA at the top when it comes to strength and performance.
Pinneberg/Germany, April 2022 – Polyamides (PA) compounds have a lot of industrial applications and are well spread in almost all key industries from automotive and consumer products to electronics and medical/healthcare sectors. Although standard PA compounds (e.g. PA6 and PA66) have found their way into expansive industries still their high level of moisture absorption remains as a main concern. Basically, moisture absorption results in remarkable degradation of mechanical, thermal, and chemical properties of the PA parts over their service period. High-end fully aromatic polyamides with less moisture absorption are considered as a solution; however, they are costly and sometimes special processing condition need to be conducted. The newly developed ROTEC® HPPA is a high performance polyamide that fills the process and performance gap between standard polyamides and the high-end aromatic polyamides. ROTEC® HPPA contains an aromatic ring in its main chain that provides superior advantages, mainly higher strength and slower rate of moisture ab[1]sorption. These make ROTEC® HPPA well-suited for variety of applications; especially cost-effective alternative to metals due to its high strength to weight ratio.
ROTEC® HPPA CHARACTERISTICS:
> A unique combination of metal-like strength and aesthetics
> Very high rigidity and resistance to mechanical stresses
> Excellent flowability; suitable for very thin wall parts or injection of large structural parts
> Low thermal expansion
> Very smooth and high gloss surface even with high glass fiber content; suitable for painting, metallization or producing naturally shiny parts
ROTEC® HPPA ADVANTAGES OVER STANDARD PA6 AND PA66 POLYAMIDES:
> Up to 60 % slower rate of moisture absorption
> Up to 30 % stronger, and higher rigidity
> Better chemical resistance
> Less change in weight/dimension over service period
> Higher surface quality
ROTEC® HPPA APPLICATION AREAS
> Automotive: exterior and interior parts such as mirror housings, door handles, headlamp surrounds, clutch pedals & cylinders
> Aviation: lightweight structural components
> Leisure/sports: lightweight accessories, sport bicycle frame and components, skiing bindings
> Appliances: vacuum cleaner motor supports & levers, shaver heads
> E&E: induction motor supports and safety switches, coil bobbins, stator cores
