Properties and applications

Roflex 50 application advantages:

– high LOI 32-33%, compared to standard plasticizers (LOI 24-25%) based on traditional PVC formulations (50 parts plasticizer, 100 parts PVC),

– a comparable effect on the plasticization of the material in relation to traditional phthalic and terephthalic plasticizers,

– the possibility of obtaining a PVC formulation that meets the requirements of UL-94 class V0 test,

– the possibility of obtaining PVC plastisol formulation for the production of coated fabrics that meets the requirements according to DIN 4102-1 class B2,

– more than 4 times stronger migration resistance compared to standard plasticizers based on traditional PVC formulations,

– compatibility with plasticizers that do not have a flame retardant function,

– the possibility of using the product in synergy with solid inorganic flame retardants in order to improve the flammability class of the material,

– a product in the form of a clear homogeneous liquid, enabling use in the production of transparent products.

Product applications:

– construction (technical films, roofing membranes, floor coverings),

– electronics (cable and wire insulation),

– transport (conveyor belts, tarpaulins),

– textiles (coated fabrics),

– furniture (artificial leather, projection screens),

– automotive (car upholstery).
