800cst Polyether Modified Silicone (CAS 68937-54-2) is polyether graft modified silicone copolymer. As core cell stabilizer for flexible polyurethane foam, it reduces interfacial tension between raw materials, homogenizes the foaming system. It effectively avoids bubble merging and cell collapsing, forms consistent tiny cells inside foam, and enhances the resilience and soft touch of flexible PU foam. It is an essential surfactant for soft polyurethane foam manufacturing.

Product Detail

Product Overview

800cst Polyether Modified Silicone (CAS 68937-54-2) is tailor-made polyether silicone surfactant designed for flexible polyurethane foam industry. Balanced hydrophilic and lipophilic structure provides excellent emulsification and foam stabilization performance in polyol-isocyanate reaction system. It maintains the integrity of bubble network during the whole foaming and curing stage, solving common defects such as large holes, cavity and foam collapse of flexible PU foam.

Key Features

Excellent foam stabilization capacity for continuous slabstock & molded flexible PU foam
Promote formation of uniform, fine and closed/open mixed cell structure
Effectively inhibit bubble coalescence, prevent foam collapse and surface cracking
Good compatibility with polyether polyol, amine catalysts and other PU raw materials
Stable foaming performance within wide processing temperature range

Main Applications

Silicone surfactant for continuous slabstock flexible polyurethane foam
Cell stabilizer for molded soft foam, furniture sponge, mattress foam
Foam additive for automotive seat flexible PU foam
Processing auxiliary for low-density flexible polyurethane soft foam

Usage Guidance

Typical dosage: 0.8%–2.5% based on polyether polyol weight. Mix evenly with polyol component before foaming. Adjust addition amount according to foam density, formulation and production equipment. Carry out small foaming trial to confirm optimal dosage before mass production.

Storage & Package

Seal drums tightly. Store in cool, dry and ventilated warehouse, avoid long-time high temperature exposure. Standard package: 200kg iron drum. Shelf life: 12 months under proper storage conditions.

Service Support

Test samples available for PU foam laboratory foaming test. Stable bulk supply and polyurethane formulation technical support. Welcome to inquire TDS, COA and factory quotation.
