Routine physical property?Cure condition:165? * 25min Air oven ageing test?condition —120?*72hr
Introduction:                
                 
Our company use new technical to produce the special rubber SCMn,its appearance as a white flaky, Mooney viscosity of 45, the SCMnhaving a high strength, vulcanizing method is simple, fast curing,nhigh crosslink density, low Mooney viscosity suitable fornprocessing is tank vulcanization, molding vulcanization. Comparednwith the single nitrile rubber and chloroprene rubber,the SCM havenexcellent ozone resistance and low temperature performance Comparednwith the CSM and NBR , the SCM have significant technologicalnadvantages and lower cost. It is suitable for wrapping cloth,npackage lead vulcanization process, which is widely used in rubbernhose ,wire and cable jacket.                
The advantages of SCM:                
1.Superior extrusion: Quick extrusion with smooth surface and freenfrom scorching.                
2.Superior oil resistance: Volume variation of CPE compound is verynsmall after test of 100?×72 hours with the medium of ASTM No.1noil?ASTM No.2 oil and ASTM No.3 oil.                
3.Superior weather ability: Variation of tensile strength andnelongation rate at break of the CPE compound is small afternexistence iatural circumstance for 300 hours.                
4.Superior Heat Resistance: Variation of tensile strength andnelongation rate at break of the CPE compound is small afterndeformation test of 100?×72 hours aging                
Usage:                
1. Extrusion: Put the cpe compound (which the SCM and othernadditives with the mixing rubber compound will mix ) into thenextruder feed port extrusion can.                
2. Vulcanization process: Vulcanization tank sulfide, suitable fornwrapping cloth, package lead vulcanization process, moldingnvulcanization                
3. Cure condition: 151?-60min                
Application: This product can be used to manufacture normal hosenwhich have heat resistance and Weatherability ,such as Highnpressure steel wire weaving hose ,wires and cables, hoses, conveyornbelts, automobile rubber components and rubber products.
