The foaming process is controlled easily since the viscosity of composite melts is quite great, without the addition of viscosity-increasingagent.
由于复合材料熔体自身粘度较大,不需要采用任何增粘措施,发泡工艺简单,易于操作。

The viscosity of PVC decreases and the liquidity increases with the addition of the AC blowing agentincreasing. The viscosity will increase when the addition is more than 0.8 phr.
