1. Benefits and Application
GB-CKP107, superior modified aluminum silicate,is made up of high purity kaolinite thr ough strictly controlled process of crushing,stripping,calcining,scattering and surface modification.It's mainly applied in nylon as functional filler.The main characteristics are as follows:
 Its particle is so fine as to sub-micron grade and the specific surface area is 16 m 2/g.
It has affinity with nylon after surface modification treatment and can be filled largely.
The properties of the nylon product,such as mechanics,thermotics,electrical insulation and water
resistance,are all improved after being filled with GB-CKP107. According to experimental contrast,
nylon product with GB-CKP107 is wuperior to that with mica,calcium carbonate,talcum powder,etc.
It's a nucleator and efficiently reduces product shrinkage.
Products made with GB-CKP107 have a good whiteness. 2. Typical Physical Properties
