Thermoplastics

S-PVC

S-PVC is produced by means of the most reactive organic peroxides currently supplied on the market. UI offers all standard grades in various concentrations and packaging in order to ease handling for our customers.

E-PVC

E-PVC is produced by means of persulfates in combination with respective redox systems. UI offers the full range of persulfates in various packaging out of our world-scale plants in Germany and China.

cr-PP

UI offers the complete range of liquid and PP based solids for the production of cr-PP (“controlled-rheology PP”). The final cr-PP polymer, which may have MFI up to more than 1000, is preferably used in non-woven (fibre) applications as well as injection molding.

FR Synergists

In many fire-resistant thermoplastic materials, flammability is reduced or eliminated by combining bromine compounds with synergists like antimontrioxide. Our CUROX CC grades help to significantly reduce or replace the often toxic and environmentally unfriendly FR synergists.

EPS/XPS

EPS (“expandable PS”)  and XPS (“extruded PS”) are polystyrene rigid foams which belong to the most preferred materials for packaging and insulation. Often FR grades are requested. UI offers both organic peroxides for the polymerization of styrene monomer (SM) and most efficient synergists for flame retardant (FR) EPS and XPS types.

GP-PS/HI-PS

Standard polystyrene (GP-PS) and its impact resisting modifications (HI-PS) belong to the most established standard thermoplastics. UI has a wide range of perketals and peresters which are considered state of the art Initiators for these polystyrenes.

ABS/SAN

The styrene copolymers ABS and SAN rank among the largest engineered plastics with extensive usage in automotive, electrical, household and many other applications. UI provides the full range of both organic peroxides and persulfates, as applied in the different production technologies, including emulsion, suspension, and bulk polymerization.

FR Synergists

Many finished goods in the construction industry have to be  fire resistant per certification. Bromine-compounds combined with DCUP synergists have been standard to reduce or eliminate flammability. UI’s free radical generating CUROX CC grades help to significantly reduce the necessary amount of brominated compounds and thus improve raw material costs significantly in the production of EPS and XPS.
