【Abstract】 The particle of A(D)C blowing agent has a great effect on its foaming velocity, foaming volume and so on. The reaction temperature, catalyst quantity and different added superficial activated agents were studied during the period of the oxidation of biurea.The rule which effected the particle of A(D)C blowing agent was explored to suit different demands of the market.更多还原
