Our company is mainly engaged in the recycling of various chemical raw materials, and has always been in line with the business philosophy of "sincere cooperation, trustworthiness, and commitment to environmental protection", and sincerely serves enterprises and institutions. We always adhere to the recycling method and reasonable prices with customers. Cooperation, and strive to "turn waste into treasure, environmentally friendly home, income-generating win-win"!
In PVC foam products, the purpose of adding ultra-high molecular weight polymer is: one is to promote the plasticization of PVC; the other is for the melt strength of the PVC foam material, to prevent the merging of bubbles, and to make products that are evenly foamed; It is to ensure that the melt has good fluidity and a good-looking product. Due to the different products of different foaming product manufacturers, the equipment, technology, raw materials and systems used are different, so we have foaming regulators with different properties to meet the different needs of users.
Door-to-door purchase of all inventory chemical raw materials: dyes, pigments, coatings, paints, resins, aluminum and silver pastes, rubber, hot melt adhesives, pressure sensitive adhesives, BYK leveling agents, defoamers, dispersants, UV photoinitiators, ultraviolet rays Absorbent, light stabilizer, polyether polyol, lithium carbonate, lithium hydroxide, vanadium oxide, plastic embossing ink, oleic acid, AEO, printing paste, zinc borate, hydroxypropyl methylcellulose, isobenzene Diphenol, hydroquinone, nonylphenol polyoxyethylene ether, polyethylene glycol, vinyl resin, flexible foam polyether, combined polyether, pressure-sensitive granule hot melt adhesive, recovery of menthol, flavor, vanillin , PVC polyvinyl chloride resin, recycled coconut oil lauric acid soap noodles, fumaric acid, chloroether resin, guaiacol, urotropine, zinc oxide, isocyanate MDI, TDI, white oil, glycerin, polyvinyl alcohol, Sodium alginate, etc., there are thousands of chemical names, as long as you deal with it, I will buy it, and it will be recycled within 24 hours.
Knowing from the molecular structure and the target of action, without these two characteristics, even if an emulsion can be prepared, it is not an emulsifier. This type has a certain emulsifying property. For example, sodium carboxycellulose is abbreviated as CMC or CMC-Na. It is made by carboxyl etherification of the base of natural fiber. It is a natural polymer compound. It is a fiber composed of two glucose molecules. It is composed of sugar and has the dispersing effect of a food thickener. However, cellulose has no hydrophilic, lipophilic and hydrophobic groups, and is not an amphiphilic, so cellulose is not an emulsifier. The article published by "Nature" as the research object of emulsifier made a principled low-level error. Therefore, "cross-border" research must have a grasp of the basic concepts. Therefore, not only this article loses its meaning, but also shows that it is correct. The misunderstanding of emulsifiers is universal, so a deep understanding of the "definition" of emulsifiers is very necessary. In real life, vitamins are often referred to as supplements of vitamins and trace elements or other nutrients or other products needed by the human body. For example, many manufacturers of element tablets label their products directly as vitamins.
The company recycles thousands of chemical products. Our company promises to recycle them quickly, at a reasonable price, and with professional, safe and environmentally friendly methods. Welcome your calls and sincerely look forward to cooperating with you!
