ROTEC® HPPA - a new high performance metal replacement
(PresseBox) - 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.
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 absorption. These make ROTEC® HPPA well-suited for variety of applications; especially cost-effective alternative to metals due to its high strength to weight ratio.
The high strength and rigidity of ROTEC® HPPA GF50 makes it possible to reduce weight through decrease of part thickness. In addition, ROTEC® HPPA GF50 (density 1.65 g/cm3 ) possesses very low thermal expansion close to that of aluminum (density 2.70 g/cm3 ) and zinc alloys. The combination of strength and low thermal expansion allows ROTEC® HPPA GF50 to be served as a true metal replacement solution and insert molding with metals applications.
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
