Micronized wax provides abrasion resistance and printability in printing ink formulations. Gloss and slip properties are also key considerations when selecting wax powders. In coating formulations, wax powders are used to enhance scratch resistance and abrasion resistance. The recoatability, slip properties, gloss retention or matting properties, transparency, and overall surface performance of wax powders are important.

Ft wax is an excellent, high-end candle-making material, particularly suitable for producing high-quality container candles, pillar candles, and decorative candles. High melting point: The melting point range is very broad (typically between 90-110°C), making it ideal for candles requiring high heat resistance. Hard texture: The candles produced are very hard, resistant to scratches and deformation, with a smooth surface. Low/no oil content: It contains almost no oil, meaning it burns smoke-free, odourless, and clean. Excellent shrinkage: It has a high shrinkage rate when cooling, making it very easy to remove from moulds. White/transparent: It is naturally white in colour, making it an excellent base for colouring, capable of producing vibrant hues.

The pure 5,6- dihydroxyindole is a colorless needle crystal with a melting point of 140℃, which is soluble in hot water but insoluble in petroleum ether. It is stable in crystalline state, but it quickly oxidizes into melanin-like substance in slightly alkaline solution. Because it has little irritation to human skin, it is used to replace commonly used aniline compounds (with carcinogenic, teratogenic and allergic adverse effects) as the active ingredient for blackening in some detergent products. For example, Japan's beauty source hair dye uses it as one of the main active ingredients. It is also a good antioxidant and can be used as an intermediate for the synthesis of some amino acids, alkaloids and tryptamine. In recent years, with the development of new varieties of fine chemicals, the uses of 5,6- dihydroxy flavor are constantly emerging. Many units have carried out the synthesis research of this product, but there is no report of batch supply yet. It is noteworthy that UIV CHEM has successfully broken through the mass production process, and we can provide gram-level to ton-level supply.

Polypropylene wax is mainly used for pigment dispersion and processing performance improvement, with specific applications as follows: Pigment dispersant Polypropylene wax, through its low viscosity characteristics, can significantly improve the dispersion effect of pigments in color masterbatch, especially in the production of ultrafine fiber color masterbatch and multi- layer BOPP film color masterbatch, which can uniformly wet pigment particles and enhance dispersion stability. ‌ Plastic Process In the blending of polypropylene resin, polypropylene wax can reduce the viscosity of the material, promote the compatibility between the filler and the resin, improve the demolding effect and surface smoothness of the product. Ink and Coatings Polypropylene wax can enhance ink wear resistance, reduce wrinkling, and improve the temperature resistance and transparency of printed materials. In coatings, its matte effect is significant and is commonly used for surface modification of matte paints. ‌
