Microcrystalline Wax is a special type of wax obtained by de-oiling petroleum. It is used as a viscosity agent, binder and emollient in cosmetic and beauty products and is often considered as a substitute for Paraffin wax. Unlike paraffin wax, microcrystalline wax has smaller crystals, is usually darker in color, more viscous, denser, cheaper and more elastic than paraffin wax. It is elastic and adherent because it is associated with a non-direct chain composition. According to Wikipedia, microcrystalline waxes have a smaller and thinner crystal structure and are therefore more malleable than paraffin waxes.

Sasolwax 7835 has high melting point, low oil content, white color, odorless and non-irritating, good light stability, high needle penetration and low viscosity. It has passed FDA food grade certification and is suitable for chewing gum base, sweet dispersant, cheese, food packaging, dental floss production and other industries. Meet the European Cosmetic Association (COLIPA) use standard, very suitable for the production and processing of lipstick, lip balm, decorative cosmetics, beauty products, etc. It is a microcrystalline wax product with good performance in the cosmetic industry. It is suitable for a variety of industries such as craft candle adding, hot melt glue, emulsified explosives, printing ink, etc.

 

 

 

 

 

 

 

 

 

 

 

In the one-step synthesis, the molecular weight of epoxy resin is mainly determined by the molar ratio between propylene oxide and bisphenol, the typical formula and the technical indicators of the product. The molar ratio between propylene oxide and bisphenol A Small changes will also cause great changes in product technical indicators.

The relationship between the molar ratio of raw materials and product technical indicators
The two-step method uses low-molecular-weight epoxy resin and bisphenol A as raw materials to produce epoxy resin through addition polymerization, and the two-step process to produce oxidized pe wax epoxy resin. During the entire reaction process of this synthesis method, the raw materials and products are in a molten state, so it is called the melt addition polymerization method, and its chemical reaction equation is as follows:
The molecular weight of epoxy resin is controlled by the molar ratio of low molecular weight epoxy resin to bisphenol A. The quality of the product is most related to the quality of bisphenol A, and is also related to the impurities contained in the low molecular weight epoxy resin and the variety of catalysts used.

Most of the epoxy resins used in powder coatings have a softening point in the range of 80~110°C. If the glass transition temperature of the resin is too low when it is lower than 80°C, it is not easy to smash at room temperature, and the storage stability of the manufactured powder coatings is not good; When the softening point of the surface resin is higher than 110℃, the melt viscosity of the resin under baking and curing conditions is too large, and the leveling of the coating film is not good, but there are also special types of epoxy resins with a softening point as high as 130℃, which are mainly used for adjustment. The performance of epoxy resin is used. There are many varieties of bisphenol A epoxy resin abroad, but the main varieties of domestic bisphenol A epoxy resin are powder coatings based on E-12 (604) epoxy resin and with narrower technical indicators than E-12 epoxy resin. Special resin. Technical index of bisphenol A epoxy resin used in powder coatings in my country. Promulgated the national standard (GB/T278092010) of the factory “Bisphenol A epoxy resin for thermosetting powder coatings”, technical indicators for epoxy resins for powder coatings.
