Product Name:Polyolefin Elastomer 891
English Name:Polyolefin Elastomer 891
CAS No.:26221-73-8
Aliases:Polyolefin elastomer 891, Ethylene-octene copolymer elastomer 891
Molecular Formula:(C2H4)x(C8H16)y
Physical Properties:POE 891 is a polyolefin elastomer copolymerized from ethylene and octene, with its molecular structure featuring physical cross-linking points formed by soft octene segments and crystalline ethylene segments. It has a density of approximately 0.865-0.880 g/cm³ and a melting point of about 60-90°C. The molecular structure contains no unsaturated double bonds, providing excellent thermal-oxidative aging and weather resistance. It also exhibits good low-temperature flexibility, narrow molecular weight distribution, good melt flowability, and excellent compatibility with polyolefins.
Uses:POE 891 combines excellent toughness and processability, and is widely used as a toughening modifier for polyolefins such as polypropylene (PP) and polyethylene (PE), suitable for automotive bumpers, cable compounds, seals, foamed materials, and other products. It enhances the impact strength, aging resistance, and weld-line strength of products, while improving filler dispersion and maintaining good processing flowability.
Technical Specifications:
Density: 0.865-0.880 g/cm³ (ASTM D792).
Melt index: 0.5-3.0 g/10min (190°C/2.16kg).
Melting point: approximately 60-90°C (DSC).
Elongation at break: ≥700% (ASTM D638).
Shore hardness: approximately A80-A90.
