Product Overview
1000cst Polyether Silicone Oil (CAS 68937-54-2) is professional silicone surfactant customized for rigid polyurethane insulation foam. The balanced amphiphilic molecular structure offers outstanding emulsification and foam stabilizing capacity in polyol and isocyanate system. It continuously protects bubble framework throughout foaming and curing, effectively solving common defects such as large voids, shrinkage and poor thermal insulation of rigid foam.
Key Features
- Powerful cell stabilizing performance for rigid polyurethane thermal insulation foam
- Promote uniform tiny closed cell formation, reduce foam thermal conductivity
- Prevent foam shrinkage, cavity and surface distortion after curing
- Great compatibility with polyether polyol, blowing agents and amine catalysts
- Stable foaming effect under different ambient temperature and density formulas
Main Applications
- Cell stabilizer for rigid PU board insulation foam
- Foam surfactant for cold storage, building exterior wall thermal insulation material
- Processing additive for pipeline polyurethane insulation foam
- Stabilizer for low-density rigid polyurethane spray foam
Usage Guidance
Normal dosage range: 1.0%–3.0% calculated on polyether polyol. Mix uniformly into polyether component in advance. Adjust dosage according to foam density, foaming method and formulation system. Small-scale foaming test is required before formal mass production.
Storage & Package
Keep drums tightly sealed. Store in cool, dry and ventilated warehouse, avoid long-term high temperature storage. Standard package: 200kg iron drum. Shelf life: 12 months under proper storage conditions.
Service Support
Test samples are available for PU foam lab foaming test. Stable bulk supply and polyurethane formulation technical guidance. Welcome to inquire TDS, COA and factory quotation.
