What role does silicone oil have in polyurethane foaming machine?

1. The strength of the membrane wall and meridians of the bubble hole can be greatly increased.

2. The reduction of surface tension is conducive to the preparation of uniform microbubbles and stable bubbles to reduce gas diffusion.

3. Reduce the mixing of impurities to avoid local surface tension of the bubble hole to cause collapse and cavity.

4. Increasing the viscosity of the material faster will help slow down the rapid thinning and foaming of the bubble hole.

5. Too much or too little silicone oil will affect the quality of foam. Dosage: make the late foam wall elastic increase, should not burst, bubble hole fine. Create the obturator foramen. Less amount: too little amount of silicone oil, insufficient foam stability, serious and bubble, bubble hole thick and uneven, even collapse bubble.

In addition, the production process of silicone oil is very complex and strict, different formulations, different processing conditions and production methods, so that the final product is very different. That is to say, different silicone oil directly affects the quality of your products, including: appearance, feel, hardness, tensile strength.

So the polyurethane foam machine silicone oil role pretty big.
