The big quantity of end-use applications for polypropylene will often be doable due to the capacity to tailor grades with precise molecular Attributes and additives all through its manufacture. One example is, antistatic additives could be included to help you polypropylene surfaces resist dust and dirt.
Superplasticizers (SPs), also known as high selection water reducers, are additives used for earning high strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with around 15% a lot less water content.
