Product application:
DEDB is an environmentally friendly plasticizer with the characteristics of strong solubility, good
compatibility, low volatility, resistant to oil, water, light, pollution etc. It is suitable for processing
PVC flooring material, plastisol, artificial leather, cable material, soft and hard pipe, shoes material,
rubber strips, synthetic rubber, and paint, printing ink, etc. It has a better plasticized effect if it is
used together with DOP or DBP, and has greatly achieved the purpose of reducing cost.
