  They maintain a consistent thickness throughout the roll, ensuring uniform performance during the thermoforming process.
• Surface Finish:
  The rolls have a smooth surface finish that is ideal for creating clean and precise forms, which is essential for high-quality packaging.

Advantage

• Protection Against ESD:
  The dissipative nature of HIPS rolls provides effective protection against electrostatic discharge, safeguarding sensitive electronic components during handling and transportation.
• Durability and Strength:
  The high impact resistance of HIPS ensures that the formed products are robust and can withstand mechanical stress, reducing the risk of damage during use.
• Versatility:
  These rolls can be used in a wide range of applications, from electronic component trays to protective covers, thanks to their excellent thermoformability.
• Cost-Effective:
  HIPS is generally a cost-effective material, and the ability to thermoform it into complex shapes efficiently can lead to cost savings in the production process.
• Consistency and Reliability:
  The consistent thickness and quality of HIPS rolls ensure reliable performance, which is critical for maintaining high standards in manufacturing and packaging.
• Ease of Processing:
  The material is easy to process, which can streamline manufacturing operations and improve productivity.

HIPS dissipative thermoforming rolls production process

HIPS particles incorporate additives that provide dissipative properties. These can include antistatic agents or conductive fillers such as carbon black, conductive polymers or carbon nanotubes, mixed in precise proportions.

Extrusion mixing: The mixed materials are fed into the extruder, where they are melted and mixed thoroughly.

Cooling and Granulation: The molten mixture is then cooled and granulated to form a homogeneous compound. These pellets will be used in the sheet extrusion process.

Feeding: Feed the composite particles into the sheet extrusion line. The line consists of an extruder with a flat die designed to produce sheet of a specific thickness.

Melting and Homogenization: Inside the extruder, the pellets are melted again and homogenized to ensure even distribution of the dissipative additives.

Extrusion: Molten polymer is forced through a flat die to form a continuous sheet.

Calendering: The sheet passes through a series of calendering rollers that control its thickness and surface finish. These rollers can also impart surface texture if desired.

Cooling: Use cooling rollers to cool the sheet to allow it to solidify.

Slitting and trimming: Trim the cooled sheet to the desired width and clean the edges.

Winding: Use a winding machine to wind the sheet into a roll. Take care to ensure consistent tension to prevent deformation.

Quality Control: The roll is quality inspected to ensure it meets required specifications including thickness uniformity, surface quality and dissipative properties.

Application of HIPS dissipative thermoforming rolls

HIPS dissipative thermoforming rolls have a wide range of applications, including:

• Electronic product packaging and shipping: Conductive dissipative HIPS sheets can be used to make electronic component trays, packaging boxes and other materials used to ship electronic products. It can help prevent ESD from damaging sensitive electronic components.
• Industrial Applications: Conductive dissipative HIPS sheets can be used as conveyor belts, guide rails, and other industrial components where static buildup needs to be prevented.
• Medical device packaging: Conductive dissipative HIPS sheets can be used in the packaging of medical devices to prevent ESD damage.
• Food packaging: Conductive dissipative HIPS sheets can be used in food packaging to prevent fires or explosions caused by static electricity accumulation.
• Other Applications: Conductive dissipative HIPS sheets can also be used in other applications such as anti-static flooring, walls and clothing.

How to make HIPS sheets conductive

Adding conductive fillers: The most common method is to add conductive fillers, such as carbon black, carbon fiber or metal powder, to HIPS resin. These fillers increase the material’s conductivity, allowing it to conduct electricity.

Use a conductive coating: Another method is to apply a conductive coating on the surface of the HIPS sheet. Coatings can be made from conductive inks, paints or metallic films.

Use chemical modification: HIPS resin can also be chemically modified to make it conductive. This usually involves adding additives to the resin, such as peroxides or coupling agents, which change the chemical structure of the material so that it can conduct electricity.

Pros and cons of each method:

Method	Advantages	Disadvantages
Adding conductive fillers	Low cost and easy to process	May reduce the mechanical properties of the material
Use conductive coating	Can maintain the original characteristics of the material	Coating may wear or peel
Use chemical modification	High electrical conductivity can be achieved	Complex process and high cost
