King PipeGrade® is a special black polyethylene material for the pipe industry.
It is available in sheets, slabs and massive shapes.

King PipeGrade® is now offering PE 4710 – PE 100 material, which is compliant to ASTM D3350 as a standard material. ASTM3350/PE 4710-PE 100 is completely compatible and 100% interchangeable for use in applications that presently use ASTM 3608 – PE 80 material.

PE4710 tends to have a higher hydrostatic design basis (HDB) than other resins but most significantly is the notched tensile/slow crack PENT test which is > 10,000 hours vs 100-200 hours for others.
