OBSH Foaming Process: From Foam bowing to High‑Quality blowing Foam
Thermal Initiation
At 140–160°C, OBSH decomposes endothermically, initiating the foam blowing process.Nucleation
Generates a large amount of gas, forming uniform bubble nuclei – this is the critical first step of foam blowing.Cell Growth
Gas continues to diffuse, cells grow uniformly, and foam blowing enters the stable expansion stage.Cell Stabilization
Upon cooling, a closed‑cell blowing foam is formed, with fine cells, no odor, and no discoloration
Advantage：
-non-blooming fast curing accelerator for rubber compounds
-non-staining accelerator for injection molding.
-effective. and stable plasticzer and process aid for most elastomers.
