It can be evaluated across general cable-insulation constructions according to the finished-cable design and required standard.

Why Choose EPC6901?

1. General-Purpose LSZH Insulation Platform

A thermoplastic LSZH / HFFR insulation grade intended for broad cable-insulation use rather than one narrow application.

2. Excellent Electrical Insulation

The supplied technical data lists a typical volume resistivity of 3 × 10¹² Ω·m, supporting its positioning as an electrical insulation material.

3. Low Water Absorption Positioning

Low water absorption is one of the key application advantages specifically highlighted for EPC6901 in the supplied product catalogue.

4. Balanced Mechanical Properties

Typical tensile strength is 13.2 MPa and elongation at break is 230%, providing a practical balance for cable insulation extrusion.

5. LSZH / HFFR Fire-Safety Profile

Typical oxygen index is 34% and halogen content is 0 ppm in the supplied data, together with flame-retardant and self-extinguishing positioning.

6. Reliable Thermoplastic Processing

EPC6901 can be processed on conventional PVC/PE extrusion equipment without a post-extrusion irradiation step.

Typical General-Purpose Cable Scenarios

The same EPC6901 insulation material can be evaluated across multiple general cable types when the project requires thermoplastic LSZH / HFFR insulation rather than a specialized application grade.

Power & Electrical Cable Insulation

EPC6901 can be evaluated for general power and electrical cable insulation constructions requiring low-smoke zero-halogen thermoplastic insulation.

Control, Industrial & Instrumentation Cable Insulation

For control, industrial and instrumentation cable constructions, EPC6901 provides a general LSZH insulation route with balanced electrical, mechanical and processing properties.

Other General LSZH Insulation Applications

EPC6901 can also be evaluated for other general thermoplastic LSZH insulation constructions when the cable design and finished-cable tests confirm suitability.
