OPaL HDPE Opalene P4002
OPaL HDPE Opalene P4002 (also searched as Opalene P4002 / HDPE P4002 / OPAL HDPE P4002) is a high density polyethylene (HDPE) polyolefin pipe-extrusion grade from ONGC Petro additions Limited (OPaL). OPaL describes P4002 as a natural-colored HDPE produced using Mitsui CX slurry polymerization technology, positioned for very good processing properties, good mechanical properties, excellent stress crack resistance, and good external appearance.
P4002 is designed for utility and agriculture pipe systems, specifically water pipes, pressure pipes for city gas distribution, and sprinkler and irrigation pipes. In market conversations, this grade is commonly positioned as a PE80 pipe grade; however, for strict technical wording, treat the PE80 designation as verified only when stated in the OPaL TDS / manufacturer documentation.

Technical insights
Pipe buyers and processors typically evaluate density/stiffness, tensile/ductility, impact toughness, thermal resistance, and oxidation stability. The following values are manufacturer-stated typical values (not specification limits) from the available TDS excerpt.
- Density 0.950 g/cm³ (23°C, ASTM D1505): Supports stiffness and dimensional stability for extruded pipe applications.
- Tensile strength at yield 20 MPa (ASTM D638): A baseline strength indicator relevant to pressure-pipe performance expectations.
- Elongation at break >500% (ASTM D638): Indicates ductility, helping pipes tolerate deformation during installation and service without brittle failure.
- Notched Izod impact >200 J/m (23°C, ASTM D256A): Indicates toughness for handling, transport, and field installation.
- Flexural modulus 900 MPa (ASTM D790A): A stiffness indicator that can support pipe rigidity and resistance to deformation.
- Heat deflection temperature 65°C (0.455 MPa, ASTM D648): A thermal performance indicator relevant to service conditions and dimensional stability.
- OIT >30 minutes (ASTM D3895): Oxidative Induction Time indicates stabilization against oxidation; relevant for processing stability and long-term performance expectations.
Note: The full provisional TDS may include additional pipe-specific performance tests, processing window, and standards language. If you need those statements verbatim for publication, pull them directly from the PDF.
Applications
Water pipes: Opalene P4002 is designed for water pipe extrusion where processors need stable processing, reliable mechanical performance, and strong resistance to stress cracking. It fits buyers searching for “HDPE water pipe grade” and “pressure pipe HDPE resin” for utility networks.
City gas distribution pressure pipes: OPaL positions P4002 for pressure pipes used in city gas distribution. In gas networks, material selection often prioritizes consistency, toughness, and crack resistance for long service life under sustained stress.
Sprinkler and irrigation pipes: For agriculture and industrial irrigation systems, processors want a pipe resin that runs well on extrusion lines and delivers dependable toughness in the field. P4002 is designed for sprinkler and irrigation pipe applications, aligning with high-intent queries like “irrigation pipe HDPE grade” and “sprinkler pipe resin.”
Comparable alternatives
Comparable HDPE pipe grades are available in India, but direct equivalence to P4002 is not confirmed unless validated via a side-by-side manufacturer TDS comparison (same designation, intended use, and comparable performance profile).
- OPaL pipe-grade basket (e.g., P5002 and other pipe grades): These may be considered depending on the target pipe standard and performance requirements, but they are not automatically interchangeable. Differences in stiffness/ductility balance, crack resistance, and any pipe-standard designation (PE class) can matter.
- PE80-positioned grades in the market: Third-party sources may label P4002 as PE80; use that phrasing carefully and anchor the final claim to OPaL’s own documentation.
- Generic HDPE (non-pipe) grades: Even if density looks similar, non-pipe grades may not be designed for pressure-pipe service or carry the same pipe-application intent. For pressure networks, prioritize pipe-grade documentation and compliance statements.
