ZARPLS – HDN3368

HDPE Natural Insulation
ZARPLS

Description

ZARPLSTM HDN3368 is a high density insulation compound designed for high extrusion speeds. HE3368 has very good flow properties and is especially designed to avoid excessive die head pressure. ZARPLSTM HDN3368 contains an enhanced stabilization system to meet the most demanding requirements

Applications

ZARPLSTM HDN3368 is designed to meet most stringent standards for heat ageing, such as Telcordia Pedestal Test and has a special stabilizer package.

ZARPLSTM HDN3368 is also suitable as outer skin in “foam-skin” constructions.

Processing Techniques

ZARPLSTM HDN3368 provides excellent surface finish and high output rates over a broad range of conditions. For normal extrusion equipment’s and applications we suggest a melt temperature and conductor preheating according to the table below:

Conductor preheating temperature: 100 – 120°C

Melt temperature 220 – 250°C

Cooling water temperature of the first part of the cooling trough: 50°C

Specific recommendations for processing conditions can be determined only when the application and type of equipment are known. Please contact your local Borealis representative for such particulars.

Extrusion

If preheating and/or drying is used, the maximum temperature should be 90ºC.

Preheating 90 °C Maximum recommended temperature
Melt temperature 180 – 190 °C
Cooling water 60 °C First part of cooling trough

Packaging

  • Octabin
  • Bags

Safety

ZARPLSTM HDN3368 is not classified as a dangerous preparation. The product is supplied in form of free-flowing granules of approximately 3 – 4 mm size and can be readily handled with commercially available equipment. Handling and transport of the product may generate some dust and fines, which constitute a potential hazard for dust explosion. All metal parts in the system should therefore be properly grounded.

Properly designed equipment and good housekeeping will reduce the risk.

Check and follow local codes and regulations!

Inhalation of any type of dust should be avoided as it may cause irritation of the respiratory system.

The product is intended for industrial use only. Please see our Safety Data Sheet for details on various aspects of safety of the product, for more information contact ZARPOLMER.
