Product Application


1. It can be used as an important component in the production of cleaning agent. Preparation formula: dissolve polyethylene glycol 4000, add triethanolamine and oxalic acid, and stir until there is no acid crystal and it is transparent solution (for reference only).
2. It plays a role in adjusting viscosity and melting point in the medical and cosmetics production industries. PEG4000 has good hydrophilic polishing performance and shape-forming property. It can be used as lubricant and coating material of dropping pill matrix, film material and capsule material for preparing tablets, pills and various capsules. It can also be used to prepare gum massage cream with functions of sterilization, anti-inflammatory and pain relief.
3. In the paper industry, polyethylene glycol 4000 can not only improve the softening effect, but also improve the stability of lotion due to its unique moisture absorption, lubrication and anti-static functions. It can be used as a finishing agent to increase the gloss and smoothness of the paper.
4. In the rubber industry, polyethylene glycol 4000 is used as an additive to play the role of lubrication and cooling, which can greatly increase the plasticity and lubricity of rubber products, effectively reduce the power loss in the production process, and prolong the service life of rubber products.
5. In metal processing industry, polyethylene glycol 4000 is used as lubricant and coolant. It can not only improve and simplify the process, reduce the labor intensity of workers, but also improve product quality, increase product added value, save raw materials and reduce product costs.
6. For pesticides and paints, polyethylene glycol 4000 has good emulsifying and dispersing properties, so it can be used as dispersant and emulsifier in the production of pesticides and pigments.
7. In the textile industry, as mentioned in point 3 above, polyethylene glycol 4000 has antistatic and lubricating properties. In addition to being used in the paper industry, it can also be used as antistatic agent and lubricant in the textile industry.
