产品描述
SABIC® LLDPE 324CE is a Linear Low Density Polyethylene natural resin typically used for wire and cable applications. SABIC® LLDPE 324CE contains a low level of antioxidants and does not contain any antiblock and/or slip agents. It also exhibits good Environmental Stress Crack Resistance (ESCR). Sufficient Cu-inhibitor should be added to meet specific ageing requirements. For jacketing applications, addition of Carbon Black or UV stabilizer is required.
Applications
- Telecommunication and Power cable (LV, MV, HV) jacketing.
- Halogen-free flame retardant (HFFR) compounds.
- One-step or two-steps silane crosslinkable for cable insulation.
This product is not intended for and must not be used in any pharmaceutical/medical applications.
Mechanical and electrical properties.
Test specimens were prepared by compression moulding according to ASTM D 4703.
