1.Introduction:
These products are the copolymer, which are formed by the ACR monomer with latex, and they are also high molecular weight polymer with multi-layer structure self developed by us.
2.The basic physical properties:
|
Specification
Item |
LP21 |
LP40 |
|
Appearance |
White freely flowing powder |
|
Granularity (percent of pass at 40 mesh) % |
≥98 |
|
Volatility，% |
≤1.5 |
|
Apparent density，g/ml |
0.35-0.65 |
|
Intrinsic Viscosity（η）① |
9.0-10.0 |
5.5-6.5 |
①The intrinsic viscosity is determined in the chloroform solution, 25 centigrade with 0.5-0.6mm Ukraine type viscometer.
3. Characteristics and Application:
PVC used in the injection of high molecular weight ACR can effectively prevent the "injection" and "white gate halo" phenomenon; at the same time increase the processing speed to make the surface smooth and shiny products will help improve the physical properties of the product.
4.Packaging
Products are packed in sealed plastic bags, and then in weave bags The net weight for each bag is 20kg or 25kg. |
