Five main types of new water reducers:

(1) Polycarboxylic acid water reducer

(2) Naphthalene water reducing agent

(3) Sulfamic acid series water reducer

(4) Modified lignosulfonate to reduce water

(5) Hybrid water reducer

In the context of water treatment chemicals, PCA typically stands for polycarboxylic acid. Polycarboxylic acids are used in water treatment processes to control scale formation and prevent corrosion in industrial water systems.

like Plasticizers for plastics are additive, most commonly phthalates, that give hard plasticsPVC the desired flexibility and durability. They are often based on esters of polycarboxylic acids with linear or branched aliphatic alcohols of moderate chain length. Plasticizers work by embedding themselves between the chains of polymers, spacing them apart (increasing of the "free volume"), and thus significantly lowering the glass transition temperature for the plastic and making it softer. For plastics such as PVC, the more plasticiser added, the lower its cold flex temperature will be. This means that it will be more flexible, though its strength and hardness will decrease as a result of it. Some plasticizers evaporate and tend to concentrate in an enclosed space; the "new car smell" is caused mostly by plasticizers evaporating from the car interior.

Tetra sodium salt of Amino Trimethylene Phosphonic Acid (ATMP.Na4) CAS No. 20592-85-2 Molecular Formula: C3H8NO9P3Na4 Molecular weight: 387 Properties of ATMP.Na4: ATMP.Na4 is the salt of ATMP, it can inhibit the scale formation, calcium carbonate in particular, in water system.
