Mineral filler fire retardant compositoin and method |
摘要 |
An improved mineral filler fire retardant composition and method are provided wherein the filler is surface treated with a polyfunctional isocyanate. This surface treatment reacts to form a polymeric coating thereby reducing both the free moisture and soluble soda level. This improved filler results in superior physical properties in polymer resins and improved processing characteristics in urethane foams.
