Roflex 65 is a flame retardant plasticizer used in the production of flexible PVC. Roflex 65 is a non-phthalate product, based on phosphate esters, combining the function of plasticizer and flame retardant. The plasticizer effectively moistens the polymer grain, enters the structure of the compound and pushes the polymer chains to form a flexible material.

Properties and applications

Roflex 65 application advantages:

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

 – 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 of DIN 4102-1 class B2,

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

 – viscosity 64-75 mPa * s at 25°C, a parameter of importance in the production process of plastisol pastes in the production of coated fabrics,

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

– the possibility of use in a formulation together with solid inorganic flame retardants to improve the fire class


– 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).
