Advantages & Use of TiO2 in Plastics
Learn from one of the most experienced experts in TiO2 technology about the key benefits of TiO2 and performance factors that effect white pigment grade selection for plastic applications.
Grade Selection

An exhaustive brochure to help you in finding the most suitable DuPont titanium dioxide grade for your specific application. This document describes the performance of DuPont titanium dioxide grades main polymer families and identifies the properties required for your application.

Polymers, Light & Science

Discover the optical properties of DuPont titanium dioxide in polymer applications. Titanium dioxide is the most important white pigment used in the polymer industry because it scatters visible light, thereby imparting whiteness, brightness, and opacity when incorporated into a plastic product.

Light Scattering Properties

Special Study : Light Scattering Properties of Representative, Morphological Rutile Titania Particles. The light scattering performance of TiO2 pigment depends intimately upon particle size, size distribution, shape, and dispersion quality. TiO2 particles exhibit complex shapes and have anisotropic optical constants.

Optimization of Highly Loaded TiO2

Special Study : Optimization of Highly Loaded Titanium Dioxide and Polyethylene Masterbatch Formations for Batch Compounding Machinery. This report demonstrates how a batch may be optimized for masterbatches of 70% by weight pigment in LDPE.

Determination of maximum pigment loading in polymer melts

A method is described for determining the maximum loading of pigment in a masterbatch. Results are given for R-101 and R-104. The former has a value lower than the predicted maximum packing at 220?, but the latter is near or greater than this maximum value.

Measurement of Viscosity and MI for R-101, R-104, R-103, and R-103 (08)

Viscosity was measured as a function of shear rate and melt index as a function of % TiO2 for the four materials.

DuPont™ R-105 for PVC windows profile

DuPont™ R-105 is a rutile titanium dioxide pigment specifically designed for outdoor plastics applications. It produces a bright, clean white material with optimal durability and excellent processibility, all backed by outstanding DuPont technology.

Die Swell and Rheology of HDPE/LDPE Blends

It is common practice to use Low Density Polyethylene (LDPE) carriers for pigment and additive masterbatches for let down into High Density Polyethylene (HDPE) formulations to make a final product. The rheological implications of the resulting blends are the subject of this note.

Discoloration of Pigmented Polyolefins

Factors contributing to discoloration of pigmented polyolefins were examined and ways to prevent HALS accelerated discoloration were suggested.

Effect of Titanium Dioxide on Slip Agents in LDPE Film

The effect of titanium dioxide on the slip agents, erucamide and zinc stearate, in controlling the coefficient of friction on cast films of Alathon 20 was measured. Small differences were noted between R-101 and R-104 but the significance was not determined.

Lacing Resistance

Variables that contribute to lacing in thin films are examined and suggestions made for increasing lacing resistance.

Theory and Practice of Polymer Film Pigmentation

A study was conducted to determine whether the measured tinting strength of grades of TiO2 could be shown to have a direct relation on the achieved opacity of films containing those grades. Differences in VTS were shown to compare directly to relative amounts of TiO2 in a film necessary to achieve equivalent opacity in the film.

DuPont™ TiO2 in Polymers and Rubber

Properties of various grades of rutile and anatase TiO2 are discussed as well as their performance in rubber. R-103 was found to be the rutile grade of choice for rubber.

TiO2 Photochemistry and Color Applications

Titanium dioxide (TiO2) is one of the most commonly used pigments in the coloring of plastics. TiO2 not only provides opacity, but it is also an excellent UV absorber. Hence, the pigment provides opacity and protection for plastics. This paper reviews the sources of TiO2 photochemistry and methods of controlling photoactivity.

Vinyl Troubleshooting

This guide outlines the process technical service support uses to characterize, define, and resolve inquiries concerning vinyl materials. Possible causes of color changes in vinyl are also summarized.
