Alkatuff® LL711UV was designed by Qenos to provide an outstanding level of protection against UV degradation (oxidation) for rotomoulded tanks. Incorporating a UV and thermal stabilisation package, Alkatuff® LL711UV enables tanks to withstand harsh climatic conditions and maintain their strength and integrity. All Alkatuff® polymers are made using a hexene (C6) comonomer rather than a butene (C4) comonomer. International research and industry evaluation shows that hexene (C6) gives superior impact strength and better Environmental Stress Crack Resistance (ESCR). These are two important properties for the durability and lifetime of a rotationally moulded product.
