The main description:
It is the copolymer of acrylamide and acrylic acids,using polymer mesh structure to increase hydrogen bonding number in the mutual area of fiber to fiber.Its combination area of long chain polymers can be deformed,thus increasing the bond toughness.It could improve the tensile strength,stiffness, ring-crush strength, bursting strength, folding endurance and other physical index.And it also can improve the retention rate of the fine fiber and filler and drainage performance.
The main Application:

1. It is specially suitable to Kraft paper,board paper and corrugated paper etc.
2. It is also suitable for paper-making system that does not add or only add a small amount of aluminum sulfate or PAC, can also exert a good paper strength enhancing effect and improve the dry strength of the retention and drainage.
3. it has a good effect in a papermaking system with a large amount of anionic impurities or a high electrolyte concentration. 2. It will increase  the "Ring Crush Test" (RCT) and "Concora Medium Test" (CMT), Bursting Strength. 
4. This DSR can also improve the retention rate of the fine fiber and filler and drainage performance.
5. The dosage DSR 20% is usually 4kg to 10kg ( 0.8 to 2.0kg/ton dry basis), the actual dosage is based on the strength demand of the customers.

4.When diluted with clean water,the dilution multiples of this product is generally about 10 times or more. After the product was stirred sufficiently,add uniformly to the slurry. However, depending on the state of dilution, it is sometimes necessary to appropriately change the dilution factors. Due to the product with high viscosity, it is recommended to use a serial dilution addition device.
5. Adding position that selected should have a full contact with the slurry. Generally choose the ingredients pool, high box or import pump. Based on the actual situation of the customers.
6.Use a plastic or stainless steel as the material for product's storage,dilution tank,piping etc..Iron-based material will cause corrosion and thickening phenomenon.
7.Do not mix with other chemicals when storage or using.
Packing & storage:
Packing: 200kg PE drum or 1000kg IBC drum.
Storage: Store in a cool, dry place, protecting from moisture, temperature 5°C to 35°C. However, when stored for a long time after dilution, or when the pH of the diluent is neutral or alkaline, the performance is lowered.
When loading and unloading, you should take care to prevent packaging and containers being damaged, avoiding leakage.
