a plasticiser allows polymer chains to slide over each other more easily :)
Masonry cement is similar to OPC but has a plasticiser added to the cement powder. As a bag of masonry cement contains 75% cement powder and 25% plasticiser, a higher proportion of cement must be used.
Plasticisers are products of the chemical industry; each plasticiser has a specific receipt and a specific technology of preparation. See also the link below.
Any rubber cant be processed without plasticiser. Hence oil acts as plasticisor. Agin we have to select different oil for different rubber.
It depends on the age of the mortar. Today's mortar is made from sand, Portland cement and water. In very cold weather a plasticiser is added. Prior to about 1900 mortar was made from sand, lime and horse-hair.
Rust is a term reserved fro the oxidation of metals. Glass cannot "rust"/"burn": it an oxide already. However, fibreglass is made out of glass and plastic, the former can crack and the latter may loose its plasticiser (i.e. old plastics items go brittle), so old fibreglass is brittle and powdery.
This post does not directly answer the question posed, but opens an issue that is relevant to their use. I have a concern about the increasing use of synthetic plastic wine corks, quite apart from the sustainability aspect of the argument. Plastic corks are most likely impregnated with plasticiser chemicals, to render the cork malleable and (I guess) to provide lubrication for their insertion into the neck of a wine bottle. Of course, corks made from the natural material do not need chemical intervention apart from sterilisation - they are naturally malleable. My concern, felt for some time now, is that the plasticiser in synthetic corks may leach into the wine on prolonged contact - I do not know if this aspect of their use has been looked into. I remember that there was a scare some years ago, about the migration of plasticisers in PVC cling film into the food it was used to protect. This resulted in the launch of a few 'safer' alternatives, appearing to justify these concerns, but the whole issue melted away through apathy, and remains inexplicably quiet. Does anyone have any knowledge of any work that has been done in this area, to establish whether the use of synthetic corks in wine bottles is toxicologically safe?
UPVC is unplasticised, rigid, PVC. PVC resin must be compounded with various additives to make it a useful product. Heat stabilisers, pigments, lubricants,process aids, impact modifiers and fillers are all added to the raw PVC resin to allow it to be processed into a durable product. If a liquid plasticiser is added to the PVC compound the finished PVC product becomes flexible, ie, no longer rigid.
sugar is homogeneous Because 1. sugar homogeneous in light of the fact that its one compound 2. iron filings homogeneous on the grounds that its one component (Fe) 3. granola bar heterogeneous in light of the fact that its produced using distinctive fixings 4. plastic wrap is homogeneous yet just on the off chance that it has no plasticiser in it. 5. concrete walkway heterogeneous in light of the fact that it is a blend of sand, bond and water.

They got their education by secretly learning it if their master didn't allowed because it was illegal. Sometimes, their masters tought the slave even though it was against the law. By secretly learning it, they could learn it off another slave or steal a book and educate themselves.
