Plasticizers In Polyurethane Products

Polyurethane itself can change its hardness by adjusting the composition of the raw materials. Plasticizers are mainly used in polyurethane compounding rubber. The purpose of use is to increase the plasticity of the compounding rubber, improve the processing performance and the low temperature performance of vulcanized rubber, and reduce the hardness of vulcanized rubber Strength. The amount of plasticizer should not be too large, otherwise the wear resistance of vulcanizate will be reduced.


Phthalates (DOP, DBP) can be used in soft elastomers with excellent migration resistance.


Fatty acid dibasic acid esters (DOA, DOS) have good cold resistance, and are mostly used for products with low temperature resistance. They can also be used as high temperature lubricants.


Dioctyl terephthalate (DOTP) has good electrical properties and cold resistance, low volatility, higher plasticizing efficiency than DOP, and small volume resistance. It is used for products with high insulation, resistance to extraction, heat resistance and flexibility. Suitable for plasticizers such as polyurethane and polyvinyl chloride resin.


JJIAAO specialized in manufacture of the the eco - friendly PVC Plasticizers, like DOTP / ESBO / DINCH / DOA/ DOS / TOTM / EFAME, our JLD800 can be widely apply in polyurethane products production.
