Technical Data

 

产品说明

CONTINUUM™ DGDC-2502 NT Bimodal Polyethylene Resin is produced using UNIPOL™ II process technology. This product may be utilized for pipe applications where long-term hydrostatic strength combined with outstanding resistance to slow crack growth, rapid crack propagation, chlorinated water and high melt strength is desired. Suitable applications include natural gas distribution pipes, large diameter industrial piping, mining, sewage, and municipal water service lines. DGDC-2502 NT has excellent processability for the full range of pipes sizes and wall thicknesses to include heavy wall pipe.

 

Industrial Standards Compliance:

ASTM D 3350: cell classification

• Natural - PE445574A CC3 

• Black - PE445574C CC3 (see Notes A and B) 

• Plastics Pipe Institute (PPI): TR-4Natural Pipe - CONTINUUM DGDC-2502 NT ASTM PE4710 pipe grade - 1600 psi HDB and 1000 psi HDS @ 73°F, and 1000 psi HDB @ 140°F 

• Black Pipe - CONTINUUM DGDC-2502 BK (see Note A & B)ASTM PE4710 pipe grade - 1600 psi HDB and 1000 psi HDS @ 73°F, and 1000 psi HDB @ 140°F 

• ISO PE100 pipe grade - MRS 10 @ 20° C 

• NSF International: Standard 14 and 61

Consult the regulations for complete details.

 

Notes:

(A) The first five numbers of the cell classification are based on natural resin. The last number and letter are based on black resin (natural resin plus 6.5% DFNF-0092 BK). 

(B) Natural resin extruded under proper conditions with 6.5% carbon black masterbatch DFNF-0092 BK.
