Acrylic Impact Modifier Da-50 - White Powder, 0.4-0.55 G/cm³ Bulk Density, Superior Weather Resistance, Excellent Impact Strength, Low Melt Viscosity

We are manufacturer, supplier and exporter of Acrylic Impact Modifier in Zibo, Shandong Sheng, China with following details.

Product name: acrylic impact modifier
Our brand: DA-50
Cas no.: 25852-37-4

Character:
Acrylic impact modifier DA-50 is a core-shell type of copolymer consisted of rubbery core (butyl acrylate) and glass shell which is compatible with pvc, rubbery core transfers the external impact energy into heat and grafted shell provides perfect compatibility of impact modifier with pvc matrix, therefore it shows excellent impact-strength, weather-resistance and color durability under long-period exposure to outdoor conditions.

Advantage:
--excellent weather ability: long-term weather resistance and impact and color retention.
--superior surface finish: the wide processing window of DA-50 assures a consistently flawless "satin" surface finish.
--good low-temperature impact
--improved process ability: because of the low melt viscosity of DA-50, extrusion temperatures are lower, resulting --in enhanced compound stability and output.
--high output: the low melt viscosity of DA-50 allows higher output without increasing extruder amps.
