NYACOL® offers colloidal dispersions and powders for use as PET additives in the production of film, fiber and bottle resin. Some materials are supplied as ethylene glycol dispersions or powders, and are added in the polymerization process for the production of PET resin. Recently, NYACOL® introduced its first clear fast reheat masterbatch product for PET, SN902-MB.
NYACOL® SN902 along with SN903 are clear fast reheat agents providing exceptional performance in PET bottles. SN902 is a 50 nm dispersion of antimony tin oxide and provides a superior balance of properties in bottles. The reheat performance can be controlled over a wide range without affecting haze and color of the bottles. SN902 is approved by the FDA under FCN1437 for use up to 500 ppm in all PET bottle conditions.
NYACOL® SN902-MB is a masterbatch product for PET. SN902-MB changes the way that PET preform makers and bottle blow molders can address their clear fast reheat requirements. SN902-MB is added at the preform product stage and can be dosed to meet a particular reheat objective for the bottle design. In PET film, SN902-MB can be used to improve the heating uniformity of BOPET and also to provide IR blocking and absorption in PET films. The standard masterbatch is 1% active as the use levels are low. We have demonstrated up to 10% active is possible and can be supplied if the application requires high loadings. SN902-MB is FDA approved as well.
NYACOL® DP5820, DP5480, DP5540 and S200-EG are amorphous silica dispersions in EG used for high performance antiblocking and control of the coefficient of friction. The materials are added in polymerization and the range of particle size allows the user to dial in the performance required. These products have been used in PET film since 1993.
NYASIL amorphous silica powders are nano-structured additives for PET film antiblocking where micron sized materials are needed. NYASIL 20 is the most popular grade with a D50 of 2 microns and a surface area of 135 m2/g.
NYACOL® DP6095 is a calcium carbonate dispersion of 0.4 to 0.6 microns mean size. DP6095 is used in specific applications where the surface roughness requirement of the PET film requires the particle of DP6095.
NYACOL® TiSol EG and NYACOL ITO-EG are development products being offered for UV absorption and high performance IR absorption respectively. Refer to the respective data sheets for the UV/VIS/IR curves to see if the new additives meet your requirements.
We are continuously adding new products for this application, so contact us to discuss your requirements.
