"Plastic modification POE Mitsui Chemicals DF940 clear, transparent, soft and foamable, high-elasticity POE" detailed introduction
Plastic modification POE Mitsui Chemicals DF940 Clear, transparent, soft, foamable high-elastomer POE Details:
POE plastics are thermoplastic elastomers that use metallocene catalysts for in-situ polymerization of ethylene and octene.
POE is divided into two types, one is a polymer of ethylene and butene, the other is a polymer of ethylene and butene. One is a polymer of ethylene and octene.
POE塑料是采用茂金属催化剂的乙烯和辛烯实现原位 A polymerized thermoplastic elastomer characterized by:
(1) Soft chains of octene The coiled structure and crystallized ethylene chains act as physical cross-linking points, giving it both excellent toughness and good processability. (2) There are no unsaturated double bonds in the molecular structure of POE plastic, and it has excellent aging resistance. (3) POE plastics have narrow molecular weight distribution, good fluidity, and good compatibility with polyolefins. (4) Good fluidity can improve the dispersion effect of fillers and also improve the weld line strength of products.
随着POE塑料含量的增加，体系的冲击强度和断裂伸 The growth rate has been greatly improved. It can be seen that POE plastic has excellent toughening effect on PP, and has good compatibility with PP and activated calcium carbonate. This is because the molecular weight distribution of POE plastics is narrow, and the side octyl group in the molecular structure is longer than the side ethyl group, which can form a connection point in the molecular structure, which plays a role of connection and buffering between the components, so that the system can be dispersed when it is impacted. , The function of buffering impact energy, reducing the chance of craze developing into cracks due to stress, thereby improving the impact strength of the system. When the system is under tension, since the network structure formed by these connecting points can deform greatly, the elongation at break of the system increases significantly. When the content of POE plastic increases, the tensile strength, The flexural strength and flexural modulus have decreased, which is determined by the performance of POE plastic itself, so the content of POE plastic should be controlled below 20%.
POE塑料的含量与熔融指数的关系，加入POE塑料后， The melt index of the system increases. POE plastic itself has good fluidity. Its addition also improves the fluidity of the entire system. When the content of POE plastic exceeds 15 parts, the melt index of the system basically does not change. If you want to continue to improve the fluidity of the system, then Can't rely entirely on POE plastics.
应用范围
Mainly used to modify and toughen PP, PE and PA to make bumpers, fenders, steering wheels, pads, etc. in the automotive industry. Insulation layers and jackets that require high heat resistance and environmental resistance in the wire and cable industry. Also used in industrial products such as hoses, conveyor belts, tapes and mouldings. Medical equipment, household appliances, stationery, toys, etc., as well as packaging films, especially suitable for low-smoke halogen-free fuels; hose packaging for cosmetics, food, etc.; Stretch film, stretch film, all kinds of cling film; also used in industrial products such as hoses, conveyor belts, tapes and molded products.
