TIOXIDE® TR48 pigment is an alumina surface-treated hydrophobic titanium dioxide pigment offering rapid and excellent dispersibility in a large range of polymers in dry processing as well as in liquid plasticizers. TIOXIDE® TR48 pigment’s fine crystal and particle sizes position it in the group of blue undertone plastics grades. It is designed for exceptional dispersion and throughput and with very low volatiles for high-temperature processing.
TIOXIDE® TR48 pigment is particularly recommended for use in systems in which fineness of pigment dispersion in the polymer combined with low volatiles is the top priority:

As for all fine powders, the handling of titanium dioxide pigments can give rise to airborne dust. Good industrial hygiene practices should be observed to avoid the generation and subsequent inhalation of dust. For more information, refer to the material safety data sheet.
The pigment should not be stored in outside areas exposed to the weather. All direct contact with moisture should be avoided. By storing the pigment correctly, its properties should not deteriorate with time. However, to ensure optimum performance, it is recommended that the product is used on a first-in, first-out basis from receipt of shipment.
