Package

Titanium dioxide for masterbatches is a versatile, high-quality additive designed to achieve opacity and whiteness in plastic products. The product is characterized by low oil absorption, excellent compatibility with plastic resins, fast and complete dispersion.

It has high opacity and whiteness to ensure the desired color intensity is easily achieved. The pigments in this product are finely ground and evenly dispersed for excellent coloring results. It provides uniform color distribution, eliminating streaks or unevenness during manufacturing. The whiteness achieved by this product is ideal for a variety of applications including film extrusion, injection molding and blow molding.

One of the outstanding features of this product is its low oil absorption. This characteristic ensures that the masterbatch maintains its vibrant color and properties even at higher filler contents. Low oil absorption increases UV resistance, which increases the durability and longevity of the end product. Additionally, this feature reduces the number of masterbatches required, saving production costs.

The good compatibility of titanium dioxide for masterbatch with various plastic resins makes it an ideal choice for plastic manufacturers. It can be easily incorporated into a variety of polymer matrices, including polyethylene, polypropylene, and polystyrene, among others. Its compatibility ensures better dispersion and mixing, resulting in a smoother and more efficient manufacturing process. Suitable for virgin and recycled plastic resins, the product is versatile and sustainable.

In terms of processing, masterbatches with titanium dioxide provide fast and complete dispersion. This means it can be easily dispersed and incorporated into plastic resins without any clumping or uneven distribution. The high dispersibility ensures that the desired color and opacity are achieved uniformly throughout the product, enhancing its aesthetics. In addition, the product's rapid dispersibility reduces processing time, helping to increase productivity and production efficiency.

In a word, this product is an excellent additive, which combines high opacity, whiteness, low oil absorption, excellent compatibility with plastic resin and fast dispersion. Its exceptional functionality makes it the perfect choice for a variety of industries looking to enhance the color, aesthetics and performance of plastic products. With our titanium dioxide for masterbatches, you can achieve the color strength, durability and process efficiency you need to meet customer demands and maintain market leadership.

KWR-639 is a rutile titanium dioxide produced by sulfuric acid process and inorganically surface treated with alumina. It is designed for masterbatch and polymer applications. KWR-639 is easily dispersed in polyolefins and has little effect on the melt flow index, so even a masterbatch with high TiO2 concentration can produce films with high hiding power and high whiteness. KWR-639 is recommended for plastic applications where high thermal stability is required. Its surface is designed to be hydrophobic, which prevents the pigment from absorbing moisture from the air.
