Dow DOWSIL FBL-1165 Silicone Formulated Blend – Frequently Asked Questions (FAQ)

Q1: What is the primary function of DOWSIL FBL-1165 in polymer systems?

A: DOWSIL FBL-1165 is a silicone-based formulated blend designed to enhance surface properties—such as slip, mar resistance, and gloss control—in thermoplastic and thermoset polymer systems. It functions primarily as a processing aid and surface modifier, improving melt flow and reducing friction during extrusion or molding.

Q2: Is DOWSIL FBL-1165 compatible with common engineering resins like polypropylene, ABS, and polycarbonate?

A: Yes, DOWSIL FBL-1165 is broadly compatible with a range of thermoplastics including polyolefins, styrenics, and engineering resins. Compatibility should be verified through small-scale formulation trials, as performance may vary depending on resin grade, additives present, and processing conditions.

Q3: How is DOWSIL FBL-1165 typically incorporated into polymer formulations?

A: It is commonly added via dry-blend or masterbatch dilution prior to extrusion or injection molding. Due to its low-viscosity liquid nature, it disperses readily in molten polymer; dosage generally ranges from 0.1% to 2% by weight, depending on the desired surface effect and base resin.

Q4: Does DOWSIL FBL-1165 affect the mechanical properties of the final part?

A: At typical use levels, DOWSIL FBL-1165 has minimal impact on tensile strength, impact resistance, or heat deflection temperature. However, excessive loading may reduce interfacial adhesion or affect crystallinity in semi-crystalline polymers—formulation optimization is recommended for critical performance requirements.

Q5: Can DOWSIL FBL-1165 be used in applications requiring regulatory compliance for food contact or medical devices?

A: DOWSIL FBL-1165 is not pre-approved for direct food-contact or implantable medical applications. Customers intending such use must conduct full regulatory evaluation—including migration testing and toxicological review—based on their specific formulation, processing, and end-use conditions.
