Application: TEGOMER® FR 100 can be used to produce halogen free, flame retardant polyolefin based on EVA and elastomeric compounds. TEGOMER® FR 100 serves as process aid for highly loaded compounds containing carbon black or mineral fillers, like aluminum or magnesium hydroxide. TEGOMER® FR 100 improves machine parameters such as extrusion head pressure and torsional moment significantly for a) untreated fillers and b) even for silane treated grades TEGOMER® FR 100 does not only work as an external lubricant as silicone oil but also in the bulk phase resulting in optimized viscosity measured with Mooney viscosimeter. By thermally initiated crosslinking reactions TEGOMER® FR 100 can be introduced permanently into polymeric resins. The use of TEGOMER® FR 100 allows the processing of high-filled HFFR compounds (up to 70 %), even with untreated ATH or MDH.

Benefits: TEGOMER® FR 100 provides several benefits to the polymer formulation such as:

• better dispersion of fillers resulting in very good flame resistant classification
• is working as internal lubricant
• higher output by optimized melt rheology
• less pressure built-up and amperage draw during extrusion
• prevents die drol
• reduced wear out at the machinery by improved melt flow
• reduced abrasion in the extruder
• less maintenance costs
• excellent char formation
• low smoking cable formulation can be achieved
• low heat and smoke release
• significantly improved Lower Oxygen Index (LOI)
