Use a plasticizer! Plasticizers: Product Properties and Applications. K-flax 500 from Noury USA – a multi-functional phthalate-based plasticizer for water-based adhesives, which produces special effects in polyvinyl acetate adhesives. It is particularly effective in acrylic latex fillers, and it exhibits excellent solubility in plastic sols and dry-mixed vinyl formulations. K-flax DE from Noury in the United States has superior performance in various aspects compared to DOP and DBP. It also features high plasticization efficiency, low toxicity, good compatibility with polymers, low volatility, low leaching tendency, a high capacity as a filler, and high brightness in the resulting products. Its performance is comparable to that of DOP, making it an excellent primary plasticizer for many resins such as polyvinyl chloride and polyvinyl acetate. K-flax DP from Noury in the United States is a highly soluble benzate-type plasticizer. It is widely used in fields such as elastic flooring, polyvinyl chloride (PVC), polyurethane, nitrile rubber, adhesives, inks, and sealants; it is particularly suitable for polyurethane and nitrile rubber. DINCH is an original German product packaged in iron drums, with a net weight of 200 KG per drum. Hexamoll DINCH is a phthalate-free plasticizer that has undergone rigorous toxicology tests in Europe; its excellent toxicological properties make it the preferred choice for sensitive soft PVC products such as toys, food packaging, and medical supplies. It can be used to produce toys for children under three years old, as well as in low-odor automotive cables, medical nutrition delivery tubes, adhesive films, household food-contact gloves, environmentally friendly indoor wallpapers, decorative sheets, intravenous infusion tubes, and medical blood bags. The competing product DINCH ATBC is a non-toxic, odorless, and safe plasticizer with excellent heat resistance, cold resistance, light resistance, and water resistance. Suitable for food packaging, children's toys, medical products, and other fields. Trin-butyl acetyl citrate, abbreviated as ATBC, is the most widely used citrate ester plasticizer. It features being non-toxic, odorless, and possessing excellent heat resistance, light resistance, and water resistance. It can be used in plastic products such as food packaging, children's toys, and medical products. The T*B plasticizer produced by T*B EAST MAN is used in the processing of emulsions such as VAE and PVAc. T*B is a water-based plasticizer that is environmentally friendly, and it is primarily used as a substitute for the conventional DBP plasticizer. When the final products made using T*B are exported to Europe, the United States, and Japan, they will comply with those regions’ import regulations. However, products made with ordinary DBP do not meet the import requirements and cannot be imported! As a result, most large enterprises as well as those from Hong Kong and Taiwan have begun to use water-based plasticizers in their formulations, with T*B being one of the important options available. The product data for T*B is as follows: T*B PLASTICIZER is primarily used as a substitute for conventional DBP plasticizers. Its main advantage is that it does not contain the harmful substance \"PHTHALIC\", making it a water-based and environmentally friendly plasticizer. The key advantages of T*B over DBP are: a higher viscosity-increasing ratio; a lower Tg/MFFT (lowest film-forming temperature); and stronger adhesion. Santicizer 9100, which is dipropylene glycol dibenzoate, has obtained the relevant certifications in the EU, the United States, and Japan, and fully complies with the standards of RoHS-Directive 2002/95/EC. Its introduction will bring new business opportunities to Chinese toy exporters. Santicizer 9100 is a primary plasticizer with high solubility, and it has a lower solidification temperature than any dibenzophosphate plasticizer. The Santicizer 9100 is suitable for a variety of resin systems. It is a non-dibenzyl phthalate-type rapid plasticizing plasticizer that, compared to conventional dialkyl phthalate plasticizers, can significantly improve gelation and foaming properties. Santicizer 9100 is a major and excellent plasticizer for PVC, and can be widely used in soft PVC for various applications, such as floors, wallpapers, fiber coating, films, and sheets. In polyvinyl acetate adhesives, Santicizer 9100 provides good initial viscosity and viscosity stability to the product, enhances wet adhesion, accelerates the drying time, allows for adjustment of the open time, and improves the spreadability of the adhesive. Santicizer 9100 has good compatibility with a variety of resins, including polysulfide adhesives, polyurethanes, ethylene-vinyl acetate copolymers (EVA), cast polyurethanes, acrylic resins, nitrile rubber, styrene-butadiene rubber (SBR), ethyl cellulose, and butyl acetate cellulose. F-30 Dioctyl terephthalate (DOTP) Molecular formula: C24H38O4 Molecular weight: 390.57 As a primary plasticizer, DOTP exhibits excellent electrical properties, as well as good resistance to cold, heat, and extraction, along with high plasticizing efficiency. Suitable as a plasticizer for polyvinyl chloride resins, such as in polyvinyl chloride cable materials that require high insulation. This product can be blended with DOP in any proportion. This product is used in plasticizing pastes to reduce viscosity and extend their shelf life.
