Advantage:Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium Salt is a nitrogen-containing organic polyphosphonate, which is a cathodic type of corrosion inhibitor, with a corrosion inhibition rate 3-5 times higher than that of inorganic polyphosphates. It is miscible with water, non-toxic and non-polluting, with good chemical stability and temperature resistance, and still has good scale inhibition effect under 200℃.
Application: EDTMPS can be used as corrosion and scale inhibitor for circulating water and boiler water, complexing agent for cyanide-free plating, chelating agent and oxygen bleaching stabilizer for textile printing and dyeing industry.

Scale inhibition effect: EDTMPS can chelate with metal ions to form a macromolecular reticulation complex, this structure helps to disperse and prevent scale formation, thus keeping the system clean and running efficiently.

HPAA(2-Hydroxyphosphonoacetic acid) is a versatile chemical compound commonly used in water treatment, corrosion inhibition, and scale prevention applications. The packaging and storage of HPAA are important to preserve its stability and ensure its effectiveness. Here are the recommended guidelines:

PAPEMP (phosphonylated polyacrylic acid, also known as Poly(2-acrylamido-2-methylpropane sulfonic acid-co-acrylic acid)-modified ethylenediamine phosphonic acid) is a compound that exhibits relatively good stability under normal conditions, but like many chemicals, its stability can depend on the specific formulation and the environment it is exposed to.

Key factors influencing the stability of PAPEMP:
pH Conditions:

PAPEMP tends to be more stable in neutral to slightly alkaline pH conditions. In highly acidic or highly alkaline environments, the structure of the polymer could degrade, particularly due to hydrolysis or other chemical reactions.
Temperature:

Higher temperatures can lead to the degradation of PAPEMP, especially if the compound is exposed to prolonged heat. Thermal degradation can cause the breakdown of the polymer chains, leading to a loss of its functional properties.
Oxidizing Environments:

Exposure to h3 oxidizing agents or environments can potentially break down the phosphonate groups (which are sensitive to oxidation), reducing the stability and effectiveness of PAPEMP.
Storage Conditions:

If stored in sealed, cool, and dry conditions, PAPEMP can maintain its stability for extended periods. Exposure to moisture, light, or excessive humidity can accelerate degradation, particularly if it's in an aqueous solution or mixed with other reactive substances.
Interactions with Other Chemicals:

PAPEMP’s stability may also be influenced by its interactions with other chemicals. For example, in formulations where it's combined with other agents (e.g., surfactants, chelants, etc.), the compatibility and the chemical reactivity of the combination could affect stability.
In summary, PAPEMP is relatively stable under mild conditions but can degrade if exposed to harsh environments (extreme pH, high temperature, or h3 oxidizers). It's best to store it in a controlled, neutral to slightly alkaline environment and avoid long-term exposure to high temperatures or reactive chemicals.
