Blowing Agent auxiliary agent (Urea Ester BK- surface treatment urea)
|
|
Features:
|
Urea Ester BK-surface treatment urea is a special additive for Blowing Agent H. It has no odor, low hygroscopicity and good dispersibility in rubber compound. Due to the high decomposition temperature of Blowing Agent H, the residue after foaming has odor and cannot be used alone. Adding BK additive can effectively reduce the decomposition temperature of Blowing Agent H to 120-125 °C, and effectively remove Blowing Agent H decomposition. After the residual odor. |
|
application:
|
Urea Ester BK-surface treatment urea and Blowing Agent H, generally used as foam for natural rubber, styrene butadiene rubber, polystyrene or other rubber and blended rubber, is most suitable for the production of porous rubber soles for beach shoes.No discoloration, no pollution. When the amounts of BK and H are the same, the products prepared therefrom have substantially no odor after decomposition of Blowing Agent H. |
