JYST－31A/B
Introduction:
JYST-31A is made up of polymer polyol, grafted polyether polyol, cross linker, blowing agent, and composite catalyst. JYHR-11B is made up of TDI and modified MDI. This type of blend polyol can be used under the temperature 35-55℃. The finished foam enjoys smooth foam skin, good rebound, comfortable feeling ect. And the hardness and density can be adjusted by customer requirement. It is widely used to produce high level car seat foam, mould mattress foam, mould sofa foam etc.
