POE 8999 (CAS No.None)
- 物化性质
- 白色或半透明颗粒，密度约0.87~0.88 g/cm³，分子量分布窄，流动性好，与聚烯烃相容性好。分子链中含较长的侧辛基，可形成联结点，在各组分间起联结和缓冲作用，使体系在受冲击时能分散和缓冲冲击能，减少银纹发展成裂纹，从而提高韧性和断裂伸长率。
- 技术参数
- 分子量分布窄，具有较好的流动性，与聚烯烃相容性好。 侧辛基长于侧乙基，在分子结构中可形成联结点，起到联结、缓冲作用。 随着POE含量增加，体系的冲击强度和断裂伸长率显著提高。 体系中拉伸强度、弯曲强度和弯曲模量随POE含量增加而下降，建议POE含量控制在20%以下。 加入POE后体系熔融指数增加；当POE含量超过15份后，熔融指数基本保持稳定。

Product Name:POE 8999
English Name:POE 8999
CAS No.:26221-73-8
Aliases:Polyolefin Elastomer 8999, Ethylene-Octene Copolymer 8999
Molecular Formula:(C2H4)x(C8H16)y
Physical Properties:White or translucent pellets with a density of approximately 0.87–0.88 g/cm³, narrow molecular weight distribution, good flowability, and favorable compatibility with polyolefins. The longer side octyl groups in the molecular chain can form junction points that provide bridging and cushioning among components, allowing the system to disperse and absorb impact energy, reducing the development of crazes into cracks, thereby improving toughness and elongation at break.
Uses:Mainly used for toughening modification of polypropylene (PP). It has good compatibility with PP and activated calcium carbonate, improves filler dispersion, and enhances the impact strength and weld line strength of molded parts. Suitable for automotive components, appliance housings, and various impact-resistant plastic products.
Technical Specifications:
Narrow molecular weight distribution with good flowability and excellent compatibility with polyolefins.
The side octyl groups are longer than the side ethyl groups and can form junction points in the molecular structure, providing bridging and buffering effects.
Impact strength and elongation at break of the system increase significantly with increasing POE content.
Tensile strength, flexural strength, and flexural modulus decrease with increasing POE content; the recommended POE content is below 20%.
The melt flow index of the system increases after adding POE, and remains basically stable when the POE content exceeds 15 phr.
