Introduction Of Polystyrene ESD Compound
- PS 302AN is a modified Antistaic compound for HISP thermoforming film or sheet, which performs permanent antisatic properties with surface resistivity of 10E7 Ohms/sq. PS302AN is also used as an antistatic masterbatch by dosage 50% -75% depending on the kinds of resistivity requirements. Non-migratory effect and non-bleeding out effect on the surface of end products, stable antistatic performance.
- PS ESD compound is an antistatic modified material with permanent antistatic properties based on polystyrene (PS). The surface resistance of this compound is 10E7-10E8 Ohms/sq, which is suitable for extrusion and injection molding.Polystyrene antistatic masterbatch is a concentrated version of PS ESD compound. It has a lower surface resistance of 10E7 Ohms/sq and is recommended to manufacturers of PS sheets and films.
- PS ESD compond can be used in fields with strict requirements for static control, such as electronics, electrical, communications, semiconductors, medical equipment, chemicals and other industries. In these fields, the use of Polystyrene antistatic material can prevent static electricity from damaging sensitive electronic components and circuits, prevent static electricity from adsorbing impurities such as dust and affecting product quality and performance, and reduce safety risks such as fire and explosion caused by static sparks. For example, it can be used to manufacture packaging materials, antistatic trays, conveyor trays, carrier reels, electrical housings, electronic parts, and accessories for electronic components.
Characteristics Of Polystyrene ESD Compound
- Permanent antistatic performance: 10%-25% antistatic additives are usually added to ESD PS compounds, which can effectively reduce or prevent the generation and accumulation of static electricity so that PS plastic products have a lasting antistatic effect.
- Excellent processing performance: It can be processed by a variety of common processing methods, such as injection molding, extrusion, blow molding, etc. The processing process is relatively easy to control and can produce plastic products of various shapes and complex structures.
- Good chemical stability: It has good tolerance to most chemical substances, is not easily corroded by acids, alkalis, organic solvents, etc., can still maintain stable performance in some special chemical environments, has good aging resistance, and can maintain good performance and long service life during long-term use.
- Relatively low cost: Compared with most antistatic materials, the cost of PS ESD compounds is relatively low, which has extremely low surface resistivity. It has a high gloss and can meet application scenarios with high requirements for product appearance.While meeting the requirements of antistatic performance, it can reduce costs for enterprises and improve product competitiveness.
- Recyclable: Polystyrene is a recyclable material that meets environmental protection requirements, is conducive to reducing environmental pollution and resource waste, and can be recycled and processed into plastic products many times. It can be used in packaging areas with high hygiene requirements such as food and medicine.
Extruding Processing Of Polystyrene ESD Compound
PS ESD compound is widely used in the production of antistatic Polystyrene sheets. According to different surface resistance value requirements, we can provide PS ESD compound 620AN or Polystyrene antistatic masterbatch 600AN. 620AN is a specialized ESD compound customized according to surface resistance, antistatic masterbatch is dry-mixed by the user in proportion according to different surface resistance values and then extruded. Polystyrene antistatic masterbatch is more cost-effective than PS ESD compound.The following are the extruding processing procedures of antistatic Polystyrene sheet:
- Prepare the required PS ESD compound 620AN according to the parts by weight: 85-90% of 620AN, 5-10% of composite toughening additives, and 1-2 % of other additives.
- Place the prepared ingredients in a high mixer and mix evenly.
- Dry the mixture with hot air at 85-95°C for 4-5 hours.
- Place the dried mixture in a sheet extrusion machine for melting, blending, and extrusion molding. The processing temperature needs to be controlled reasonably, generally, the processing temperature of the PS ESD compound is about 10 degrees lower than that of regular PS resin.
The processing technology of antistatic Polystyrene sheets may vary depending on specific uses and requirements, It is recommended to adjust according to actual needs.
