Material with a higher mechanical strength, stiffness, heat and wear resistance than ERTALON 6 SA it also has a better creep resistance but its impact strength and mechanical damping ability are reduced. Well suited for machining on automatics lathes.

This material offers an optimal combination of mechanical strength, stiffness, toughness mechanical damping properties and wear resistance. These properties, together with favourable electrical insulation ability and a good chemical resistance make ERTALON 6 SA a ‘general purpose’ grade for mechanical construction and maintenance.

Compared with the conventional nylons, ERTALON 4.6 (STANYL) features a better retention of stiffness and creep resistance over a wide range of temperatures as well as a superior heat ageing resistance. Therefore applications for ERTALON 4.6 are situated in the higher temperature area (80 150 C) where stiffness, creep resistance, heat ageing resistance fatigue strength and wear resistance of PA 6. 66. POM and PET fall short.

Compared with virgin PA 66, this 30% glass fibre reinforce and heat stabilize nylon grade offers increased strength, stiffness creep resistance and dimensional stability whilst retaining an excellent wear resistance it also allows higher max service temperatures.

The SEMITRON ESd family of static dissipative plastics is designed for applications where electrical discharge in operation is a problem (ESd: Electrostatic dissipation). Bleed – off of static charges.

Main characteristics

1. Permanently static dissipative

2.  Dissipate static charge of 5KV in less than 2 seconds per Mil-B-8175C.

3.  No metals or graphite / carbon power used.

There are four SEMITRON (POM) (beige)

SEMITRON ESd 225 is an acetal based static dissipative material ideal for material handling applications. It avoids discharge problems for parts intended for human contact. SEMITRON ESd 225 is also an excellent choice for fixturing used for handling in-process silicon wafers or used in the manufacturing of sensitive electronic components including hard disk drives and circuit boards.

The addition of Mos, renders this material somewhat stiffer, harder and dimensionally more stable then ERTALON 66 SA, but results in some loss of impact strength. The nucleating effect of the molybdenum disulphide results into an improved crystalline structure enhancing bearing and wear properties.

Reinforced with a proprietary synthetic mica, SEMITRON ESd 500 HR offers an excellent combination of low frictional properties, good dimensional stability and electrostatic dissipation. Whenever Virgin PTFE causes electrical discharge problems, SEMITRON ESd 500 HR will provide a controlled bleed – off of static charges while maintaining typical PTFE properties such as broad chemical resistance, temperature resistance low coefficient of friction.

Having an excellent mechanical performance up to 210 0C SEMITRON ESd 410C provides ESd – solutions at higher temperatures. Additionally, SEMITRON ESd 410C exhibits excellent dimensional stability (low coefficient of linear thermal expansion and small water absorption). Ideal for handling equipment in the electronic or semi – conductor industries.

High molecular weight polyethylene (PE-HMW) Ultra High Molecular weight Polyethylene (PE-UHMW)

SEMITRON ESd 529 HR has an industry first combination of electrostatic dissipation (ESd). High strength and heat resistance. This new ESd material is ideal for making nests, sockets and contactors for test equipment and other device handling components in the semiconductor industry. The key feature of SEMITRON ESd 520 HR is its unique ability to resist dielectric breakdown at high voltages (>100V). whereas e.g. typical carbon fiber enhanced.

Products become irreversibly more conductive when exposed to even moderate voltages. SEMITRON ESd 520 HR maintains its electrical performance throughout the voltage range 100 to 1000V, while offering the mechanical performance needed to excel in demanding applications.

Green, red yellow, king’s blue, sky blue, salmon, orange and chestnut. Molecular weight of about 500,000 g/mol. The CESTILENE HD 500 range of materials offers a series of homogeneous attractive and food compliant colours which find particular outlet in the food and leisure industry. The property profile of these grades is practically identical to the one of CESTILENE HD 500.

Molecular weight of about 500,000 g/mol. This grade exhibits a good combination of stiffness, toughness, mechanical damping ability with wear and abrasion resistance and can easily be welded CESTILENE HD 500 R is used for those applications where its reduced physical properties are overruled by its economical advantage.
