Rubber can be seen everywhere in our daily life, rubber tires, rubber gloves, rain shoes, warm water bags, rice cooker seals, shoe soles, children's toys,
car wipers and so on. Especially in large machines, industrial equipment, automobile transportation equipment are often used rubber products.
So what is the application of peg4000 in rubber products? As an additive in the rubber industry, it increases the lubricity and plasticity of rubber products,
reduces the power consumption during processing, and extends the service life of rubber products. In the rubber, it is mainly to neutralize the acidity of the filler,
accelerate the vulcanization rate and cross-linking density, has good water solubility, and has good compatibility with many organic components, has excellent lubricity,
moisture, dispersion, and can also be an antistatic agent and softening agent.
Generally, polyethylene glycol 4000 is used in rubber, if the molecular weight is too low, the compatibility is not good, it is easy to precipitate, and it is a liquid,
it is not good to add, the molecular weight is too high, the alcohol group per unit mass is small (low hydroxyl value), and the acidic effect is almost almost,
because the molecular weight of 4000 is a solid sheet, easy to process, convenient to add, not easy to precipitate, medium molecular weight polymer,
Good compatibility with rubber, so generally choose PEG-4000.
