ACR impact modifiers generally refer to crosslinked low glass temperature (Tg) acrylate monomer polymers such as polypropylene
Butyl butyrate (PBA) as the core, with poly (methyl methacrylate) and other high Ts polymers as the shell, with two layers
Or multilayer core-shell composite polymer. It can not only effectively improve the impact strength of polyvinyl chloride (PVC), but also be used
In polymethyl methacrylate (PMMA), polystyrene (PS), nylon and polycarbonate (PC) brittle or low toughness polymers
Toughening modification. When ACR is used for toughening PVC, it can be achieved at a low dosage (generally 6-8phr)
Toughening effect, at the same time has the effect of improving PVC processing properties, toughening effect with processing temperature change is small, PVC products
Tensile strength, hardness and weather resistance are better than those of CPE and other impact modifiers modified PVC. In view of the above reasons, ACR impact modification
Agents are widely used in foreign countries, especially in Europe and North America. Almost all the anti-impact modifiers used in PVC profiles are ACR trees
Fat. Domestic due to the price, source and other factors, PVC profile production formula of anti-Impact Modifier for CPE resin, only a few
Several manufacturers began to use ACR impact modifiers.
Rohm & the United States. Hass has been developing ACR impact modifiers since the 1950s
The world's largest supplier of ACR impact modifiers, including ParaloidTM KM-300 series (KM334:, KM355, KM365)
It is suitable for PVC ACR impact modifier variety. In addition, the company has introduced HIA80 for transparent PVC products
ACR - type impact modifying agent. The development and application of ACR impact modifiers began in Beijing in the early 1980s
Research Institute of Chemical Industry, Shanxi Research Institute of Chemical Industry, Hebei University of Technology, Qilu Research Institute of Chemical Industry, Zhejiang University and other units successively advanced
Line of synthesis and application of research, and have shanxi Chemical research Institute, such as industrial production.
