DCH 21A CPE Cable Jacket Compound
Category : Polymers/Synthetic Rubber
CAS NO : EC NO : MF : MW : Specification : CPE Cable Jacket Compound Packing : 25KG/CARTON Product description : DCH 21A CPE Cable Jacket Compound Common non-extended burned rubber jacket compound under the temperature at 85℃ Ⅰ.Illustration With Chlorinated Polyethylene (here below called CPE), blended with other additives and pigments, DCH 21A Jacket has excellent properties of fire retardancy, oil-proof, tearing-proof, cold-resistance and excellent mechanical properties. With its excellent properties, excellent extruded rubber surface, good flexibility, lower density & lower cost, our 21A is the first ideal substitution of CR for shipping cable and CSM based rubber sheath. Ⅱ.Application Our DCH 21A is researched out according to our newest national standard for shipping cable. The product properties resulted from curd sheet or extrusion-rubber continuous cure all reach or over the national standard. Ⅲ.Comparison of Material Properties &Standard No. Test Item Unit GB7594-87(XH-21A) DCH21A DCH2A 1 Mechanical properties before aging 1.1 Tensile Strength MPa ≥11.0 14.0 13.5 1.2 Elongation at break % ≥250 420 435 2 Mechanical properties after aging(120℃,7days) 2.1 Change ratio of Tensile Strength(Maximum)% -15~+15 8.5 8.0 2.2 Change ratio of Elongation at break(Maximum)%-25~+25 -15 -17 3 Heat-extending test Test condition Temperature ℃ 200 Load time Min 15 Mechanical stress MPa 0.2 3.1 Elongation in load % ≤175 40 30 3.2 Permanent set after cooling % ≤25 10 5 4 Dipped mine oil test Test condition Oil temperature ℃ 100±2 Oil-absorption time h 24 4.1 Change ratio of Tensile Strength (Maximum) % -40~+40 -9 -10 4.2 Change ratio of Elongation at break(Maximum)% -40~+40 -14 -16 5 Low temperature Tensile test (-35℃) Maximum elongation at break % 90 6 Scorched time (140℃zz0 Min >30 Ⅳ.Processing Condition Continuous vulcanization production method is preferred Compression ratio: 1.1:1-1.5:1; Length-diameter ratio: 6:1-16:1(hot feed is suggested if lower than 10:1); Temperature of extruder: 65-85℃; Curing pipe’ temperature: 180-200℃ (13-15MPa). Ⅴ.Package & Storage Generally, 25kgs in one carton box or depends on customers’ requirements. Shape of the material: Rectangle rubber sheet, pellet or depends on customers’ request. The material should be stored at clean, dry, draughty warehouse. Uses : Cable Jacket Synonyms : no data
