The technical data sheet (TDS) of Dow AXELERON™ CS K‑3364 NT CPD HDPE material from Dow corporation, if there are differences, please refer to the official website of Dow.
Outstanding environmental stress cracking resistance, reducing the risk of long-term cracking failure in cable service.
Excellent low-temperature toughness with a brittleness temperature down to -76.0°C, suitable for low-temperature laying conditions.
Stable electrical insulation properties with low dielectric loss, applicable to cable products requiring high insulation performance.
High retention rate of mechanical properties after thermal aging, maintaining mechanical integrity in high-temperature environments.
Good extrusion processing adaptability, with melt stability meeting the continuous production requirements of cable jackets and insulation layers.
Excellent water immersion resistance, maintaining a low dielectric loss level after immersion.
Communication Cable Field: Communication cable insulation layers and jacket materials, suitable for overhead and conduit-laid cables.
Power Cable Field: Medium and low-voltage cable jackets, and outer layer components requiring stress cracking resistance.
Underground Laid Cable Accessories: Direct-buried cable jackets and protective cable components subjected to soil stresses.
Electrical Extruded Products: Extruded electrical parts requiring high insulation, low-temperature resistance, and stress cracking resistance.
Q1: Does Dow AXELERON™ CS K‑3364 NT CPD HDPE require drying prior to processing?
A: HDPE has a very low moisture absorption rate and generally does not require pre-drying under normal storage conditions; when affected by moisture or condensation, it is recommended to dry at 60–70°C for 2–4 hours to remove surface moisture and prevent surface defects on products.
Q2: Does this grade come with RoHS compliance documentation?
A: This material can provide a RoHS conformity statement. During actual project reviews, compliance reports for the corresponding batch can be requested from the raw material supplier for verification.
Q3: What is the core difference between this grade and general-purpose cable HDPE?
A: This grade is specifically enhanced for environmental stress cracking resistance, thermal stress cracking resistance, and electrical stability after water immersion, making it suitable for severe long-term buried and alternating high-low temperature environments; general-purpose cable HDPE is relatively weaker in these long-term aging and crack-resistance metrics.
Q4: Can this material be blended with other polyolefins?
A: It is compatible with LLDPE and other HDPE types, and can be blend-modified to adjust processing fluidity or cost; however, stress cracking resistance and electrical properties will change after blending, so small-scale sample testing and verification must be completed before mass production.
