There are two type super absorbent polymer, so choose a reliable Agricultural Potassium Polyacrylate Manufacturer is very very important, to avoid that you order the wrong Agricultural Potassium Polyacrylate
Types of super absorbent polymer
There are two type super absorbent polymer: potassium polyacrylate and sodium polyacrylate.
And there’re big differences between them:
Raw materials Price Mainly Usages
sodium polyacrylate sodium hydroxide, acrylic acid, etc. about USD 1,200/Ton for paper diaper, sanitary, etc.
potassium polyacrylate potassium hydroxide, acrylic acid, etc. about USD 3,000/Ton for agriculture
Potassium polyacrylate will absorb water and turn to water gel after rain or irrigate. And gel can release water to plant when soil is dry enough. After releasing, potassium polyacrylate gel will turn to powder/granule and waiting for next rain.
The period of validity is about 3-10 years and potassium polyacrylate can be slowly decomposed into potassium ion, ammonia, water, carbon dioxide in the soil.
So potassium polyacrylate can help plants growing well and it’s mainly used in agriculture.
For now, potassium polyacrylate ‘s price is about USD3000/ton.
Sodium polyacrylate ’s price is about USD1200 / ton. (The price of inferior type can be lower than USD1000 / ton.)
As another type of super absorbent polymer, sodium polyacrylate is mainly used in producing absorption products such as paper diaper, sanitary towel.
Unlike potassium polyacrylate, sodium polyacrylate ‘s water gel won’t release water to plants and break down in few days after mix with soil.
This is meaning, sodium polyacrylate can’t help plants growing at all. Conversely, the sodium ion will let soil hardening.
So sodium polyacrylate should not be used in agriculture.
But sodium polyacrylate ‘s price is much lower than potassium polyacrylate and it’s hard to distinguish between them, there’re some fake “potassium polyacrylate” is sodium polyacrylate in the marketing.
So choose a reliable Agricultural Potassium Polyacrylate Manufacturer is very very important, Founded in 2009, Qingdao SOCO New Material Co., Ltd. is a modern high-tech enterprise focusing on the R&D, production, marketing and service of SOCO brand high polymer products.
