The belows are our testing report.
We will ensure that we will choose the quality raw material to produce high-quality RDP and cellulose products strictly according to the Ash content and Viscosity required by our customers.
Each step, from raw materials to anti-caking tests to emulsification tests after finished products, is strictly checked by inspectors.
Each shipment is subjected to extremely stringent inspection by inspectors.
Test of redispersible polymer powder
1. Appearance test
shows that it is a white, no color difference, no impurities, no lumps.
2. Particle size test
The particle size test is carried out using a laser particle size analyzer.
3. Solid content test
The solid content test is conducted by drying a known amount of the sample at a specific temperature.
4. Bond strength test
The bond strength test of the redispersible polymer powder is an important indicator of its performance.
5. Redispersible test
The redispersible test shows that the powder can be quickly redispersed in water to form a homogeneous emulsion
6. Film-formaing test
The film-forming test is used to evaluate the ability of the redispersible polymer powder to form a film.
7. Chemical stability test
The chemical stability test is performed by exposing the redispersible polymer powder to different chemical environments.
8. Ash content test.
The ash content test is carried out to determine the amount of inorganic substances in the redispersible polymer powder.
