■ Collocation of polyether polyol for foaming

LHE-76EK, LHE-83EK mixed with high-active polymer polyol

■ Product features and advantages
LHE-76EK, LHE-83EK have higher reactivity and the product characteristics of not being able to smell with nose. Moreover, the product application tolerance is high. In the early and middle stages of foaming, the foaming rate is moderate, and the gel rate is fast in the later stage, which can meet the foaming needs of different densities and high resilience sponges in most environments.

■ Inactive polymer polyol (POP)
This type of product has stable indicators and strong operability. Possibility of changing the sponge formula is low by using the product, which is conducive to large-scale sponge foam production operations. The product has low viscosity and does not become viscous after adding water and stirring, which is conducive to the complete mixing of materials and the control of sponge cells. The product has pure white color and extremely low VOC.
