680 Silicone Oil Polyurethane Foaming Additive For Soft Foam
680 Silicone Oil is a specialized polyurethane foaming additive designed specifically for soft foam applications.
Key Features
- Reduces surface tension to facilitate uniform microbubbles and stable cells, minimizing gas diffusion
- Accelerates material viscosity increase to slow down rapid cell thinning during foaming
- Enhances cell wall and meridian strength for improved foam structure
- Reduces impurity mixing to prevent local surface tension reduction and avoid collapse/voids
- Recommended usage: 1% to 3%, adjustable based on polyurethane foam density requirements
