- CPE used in rubber
- CPE can be processed in all conventional rubber processing equipments,
can be vulcanised by chemical cross link and
physic cross link (irradiation) .
CPE mechanical properties and cost effective compare with other
chlorine based rubbers.
CPE mainly used for hoses in critical area, cable outer jacketing
/ sheathing for welder, coal mines, and marine ,also
foam, seals and other rubber products require resistance to aging,
weather, ozone, heat, flame.
- CPE features:
- Tensile; > AND =8 Mpa higher than most synthetic rubbers.
Thermal stability: 200’degree’C working temperature 150’C
Cold temperature: -35’C
Tear(twist): best among all rubber
Chemical resistant; excellent resistance to acid, alkali, oxidation
Oil; better than all rubber other than nbr
Filler; accept high filler level
Flame; good .
Waterproofing: yes and similar to IIR and CSM
Compatibility: double parlor can be blended with other rubber
or plastic at any ratio.
- CPE blending with other rubbers:
- CPE or CM ideally used for mixing with other rubbers to reduce
CPE or CM rubber chemical resistance better than EPDM, NBR, SBR.
CPE or CM heat resistance better than Butyl , CR,EPDM,NR,NBR,SBR.
CPE or CM oil resistance better than Butyl , CR, EPDM, NR , SBR.
CPE or CM flame resistance better than EPDM,NBR
CPE or CM ozone resistance better than CR,NBR
CPE /NR; improving tensile, tear strength, aging,chemical and
flame resistance .
CPE /SBR improving strength, aging,ozone, oil resistanceand better
CPE/NBR improving aging, ozone and physical properties, can use
the same vulcanization material. i.e peroxide
CPE/EPDM improving extrusion flow, adhesiveness , tensile(vulcanized)
and abrasion. and cost effective can be cured
same time with peroxide.
CPE/CR more cost effective, when blending CPE/CR ozone , strength
improved but hardness increased but oil resistance reduce.
CPE/CSM effective and easy processing
