Where is the white base material used? Please match it with your products. 

White masterbatch is a widely used color masterbatch in industries such as plastics, chemical fibers, and non-woven fabrics. It is not only used to give products a white color, but is also often used as a color base material, to improve covering power or to enhance the appearance of the products. Different downstream products have different focuses on the white degree, covering power, heat resistance and safety requirements of White masterbatch. Below, we will help you match them according to common application fields. 

I. The Field of Synthetic Fibers and Nonwoven Fabrics 

These applications require the White masterbatch to have high heat resistance, excellent dispersion properties and high purity, in order to prevent breakage of filaments or clogging of the spinneret during the spinning process. 

Chemical fiber spinning (polyester, polypropylene, nylon FDY/POY/short fibers): Used to produce the base color of white fibers or light-colored fibers. Select white mother materials with high temperature resistance (usually requiring stability at 250°C - 300°C), fine titanium dioxide particle size and narrow distribution to ensure smooth spinning and uniform fiber whiteness. When used for fine denier fibers, special attention should be paid to the filtration performance (pressure filtration value) of the mother material. 

Non-woven fabric (for medical, healthcare, and filtration purposes): Used for manufacturing white non-woven fabric. The non-woven fabrics used in medical and healthcare applications have higher requirements for the purity and safety of the white masterbatch, and it is necessary to confirm that the masterbatch complies with relevant skin-contact safety standards. When used for meltblown fabric, the dispersion fineness of the masterbatch directly affects the filtration efficiency. 

II. Plastic Products Sector 

The requirements for plastic products regarding the masterbatch vary depending on the molding method and the intended use. 

Film (packaging film, agricultural film, breathable film): Used for producing white or semi-transparent white films. The requirements are that the white masterbatch should have good covering ability and high dispersion, to avoid white spots or crystal points appearing on the surface of the film. When used for food packaging films, it is necessary to confirm that the masterbatch complies with food contact grade standards. 

Injection molded parts (daily necessities, electrical appliance casings, automotive interior components): Used to give the products a white color or adjust the base color. A general-purpose white masterbatch can meet most requirements. When used for outdoor products, attention should be paid to the light resistance and anti-yellowing performance of the white masterbatch. 

Blow-molded products (hollow containers, bottle types): Used for manufacturing white containers. The white masterbatch should have good thermal stability during the blow-molding process, without decomposition or precipitation, and with uniform covering ability. 

III. Functional Composite Fields 

When the product needs to have both white color and additional functions, a functional white masterbatch can be selected. 

Anti-static white masterbatch: Used in electronic packaging, anti-static boards, etc., it provides anti-static properties while giving a white color. 

Anti-aging white masterbatch: Used in outdoor products, agricultural films, etc., it provides a white color while offering UV resistance, thereby delaying the aging of the products. 

Open mouth white masterbatch: Used for film products, it imparts whiteness while improving the opening property of the film and preventing adhesion. 

Summary and Selection Suggestions 

When purchasing white masterbatch, it is recommended to follow the following steps for confirmation: 

Primary application: Fiber spinning, non-woven fabric, plastic film, injection molded parts, or functional composites? Different fields have different requirements for the temperature resistance, dispersion, coverage, and safety of white mother mix. 

Clarify the performance requirements again: target whiteness reference sample, coverage level, whether it needs to be resistant to light or anti-yellowing, and whether it comes into contact with food or skin.
