Talk:Plasticizer

"The solid rocket propellant used to fuel the Space Shuttle solid rocket booster employs HTPB, a synthetic rubber, as a non-energetic secondary fuel." This is actually wrong. When the Space Shuttle booster was designed about 50 years ago other binders were popular, and you don't change a working and certified propellant for no good reason. The binder employed was PBAN with an epoxy curative, the reason largely being cost, why change if it works, mechanical properties (biggest solid rocket ever produced, mechanical properties matter A LOT) etc. https://en.wikipedia.org/wiki/Space_Shuttle_Solid_Rocket_Booster#Propellant Someone correct this please. — Preceding unsigned comment added by 80.147.133.213 (talk) 19:00, 7 October 2022 (UTC)

  We may use this material by weight/weight relation

upto 12% to 30% can be satisfactorally use according to the ASTM standards

    we use C-494 ASTM standard for this

Some attempt should be made to include discussion of antiplasticizers as well. — Preceding unsigned comment added by 170.140.163.94 (talk) 17:36, 17 September 2014 (UTC)

British vs. US spellings

"The article starts with the US spelling, and toward the end, uses British ("plasticiser"). I'm not going to change the British to US spelling; I love British English (having had a British maternal grandfather). Just noting it; Wikipedia surely has a policy on such. Loved the article! Fine piece of work. Regards, Nikevich (talk) 17:54, 3 April 2009 (UTC)

Split off "concrete plasticizer"

The the section on concrete plasticizer should be slit off as a separate article. There is very little in common between the two concepts, and the term is much more often used for the plastics one.
--Jorge Stolfi (talk) 20:15, 30 June 2020 (UTC)Yes, I agree and should be added to the Propeerties of Concrete If we agree then how should this be done StuPat (talk) 14:56, 17 August 2020 (UTC) Yes, I agree it should be split. How is the question.Scoob5555 (talk) 14:42, 20 August 2020 (UTC)

Citric acid

Citric acid is often used as plasticizer for PVC products. May be worth to research and mention this fact. AXONOV (talk) ⚑ 11:03, 7 February 2024 (UTC)
