TAFMER TM DF & M Ethylene based α-olefin copolymers TAFMER DF & M is used as a modifier of Ethylene Vinyl Acetate (EVA), Polyethylene (PE) and other thermoplastics to improve its properties. It is suitable as both modifier and base resin in ethylene based Halogen Free Flame Retardant (HFFR) wire and cable jacket. General characteristics attributed to TAFMER DF & M : Low Crystallinity and for high filler containability Low Young s Modulus for Softness and Flexibility Excellent Elongation YOUNG S Young s MODULUS Modulus () DF M Grafted polar group for Scratch resistance (kg/m ) Properties such as elongation, flexibility, low temperature impact resistance and scratch resistance are improved. Heat resistance can be reinforced by crosslinking. TAFMER DF in Ethylene Based Wire s and Cable EVA EVA is commonly used as base resin in ethylene based HFFR compound. However, properties such as elongation, softness and low temperature impact resistance become poor with higher loads of Magnesium Dihydrate (MDH) flame retardant: Brittleness Surface Hardness Temperature (Shore D) - -0 4-1 50-1 5 EVA - VA content: 5 % MFR(10 ),.16 kg=.0 Hardness of EVA 85 (shore A) Resin MDH MFR (10 (Silane, Treated) 10kg) phr 10.0 100 150 100 4. 00 100 Elongation Tensile Strength at Break % 4808 100 11. 1 0 In comparison to EVA, TAFMER DF maintain the physical properties of the system with increasing MDH loads. Thus properties such as elongation, flexibility and low temperature impact resistance can be improved by modifying EVA with TAFMER DF. 1

TAFMER DF as Base Resin TAFMER DF as itself is not a heat resistant material, however, its heat resistance can be improved by various methods of crosslinking. Difference of pre-treatment of flame retardants significantly affects on bending resistance of TAFMER DF based HFFR compound., with its polar group, functions as an optimizer of bending resistance. TAFMER TM M Modified ethylene based α-olefin copolymer Grafted with polar group, does not only interact with metal hydrate, but is also compatible to Polyolefin Elastomer (POE). In ethylene based wire and cables, is used to improve scratch resistance and whitening on bending.
