LS-M821
LS-M821 is a new kind of PVC impact modifier developed by our company. It is a polymer made of methyl methacrylate butadiene and styrene by emulsion polymerization. It has a typical "core-shell", the processing performance, impact performance, transparency and other aspects of performance balance, is a general type of transparent MBS impact modifier.

Performance
*Excellent processing performance, product quality more stable
* High light transmittance, low haze
*Good impact performance
* Flocculation process, stable quality, not easy to precipitate, effectively prolong
*The machine running period
Package & Storage:
25kg/bag PP bag.
Neutral packing or OEM packing is acceptable.
It should be stored in cool and dry surroundings with shelf life of two years, it can be still used if qualified by inspection after shelf life.
Application:
PVC transparent container, pharmaceutical packaging, transparent sheet and film, etc., to improve the impact strength of the products, especially for all kinds of MBS transparent products, the dosage depends on the demand of the products and impact strength.
