Product Description


What is SAP (Super Absorbent Polymer)?


Super absorbent polymer (SAP) is a polymer material with good water absorption and
water-holding capacity. It can absorb water up to several hundred times of its own weight, and turn into natural gel from within seconds. SAP can be mainly divided into three major categories which are Hygiene grade, Agriculture grade and Industry grade. The main uses of SAP are absorbing, retaining or to block liquid.






Our SAP are widely used in agriculture, forestry and gardening, such as Soil water retention agent, seed coating, soil-less cultivation, artificial turf, forest fire, etc. It applies to water-saving agriculture and forestry in the drought-wide application prospects.



It is a new functional polymer material: innocuous and can absorb/release water circularly because of its strong absorption group and special structure (mesh structure). People usually compare it to ‘mini-reservoir’. Besides, it can also absorb fertilizer and release them slowly to increase the efficacy. This product is not only conducive to crop growth, but also conducive to soil improvement.

Local Test 






1. Common plants and crops

15 to 30 kg per acre dosage, along with seeds hole application or ditch application to the soil around the seed, the seed germination rate can effectively improve and promote seedling growth. Gets success planting corn in the U.S, pature in arid area of inner Mongolia, potatoes grown in Cape Verde Africa, and potato yield increase more than 2 times.

2. Seed coating
Seed coating use SAP should be fine particle size of 0.3 mm or less, after SAP coating the seed emergence quickly, strong and good disease resistance, this is the easy available way use SAP to plants in drought area, which also with small quantity, low cost and good performance.

3. Gardening, Horticulture and landscape
SAP is ideal for mixing soil matrix, for indoor and outdoor pots, planters, window boxes, balconies, terraces, roofs, hanging, gardens, city landscape. Planting shrub, flower, grass, vegetables are available. Using SAP can bring water-saving, labor saving, time-saving benefits and reduce the drought or wilting risk causing by long time no watering the plants, longer the green time and the blossom period.

4. Lawn and Golf course
Application in golf and lawn can save about 50%-70% water, Reduce the cost of maintenance, Save about 30%-50% fertilizer. Lawn grows faster, healthier, and the green last longer, less pollution caused by the loss of fertilizer.


5. Trees
SAP as important role like fertilizers, pesticides, it is because the development of planting saplings and fruit, a continuous supply of water is very important. Using 10-20g SAP can double the survival rate of young trees when planting tree seedlings (bare root)

For adult deciduous fruit trees, put the SAP with organic fertilizer, taken with a ring groove or furrow in the root area. The dosage is up on the soil condition, tree size and the ditching situation, should generally be 0.3% of the backfill soil and fertilizer. Liaoning and Shandong planting apple in Liaoning and Shandong, lychee and pineapple in Guangxi, bananas and peaches in Yunnan, get very good result after using SAP.
