Acrylic Impact Modifier is core-shell copolymer,lotion polymerization lotion is usually used in seed lotion polymerization, including traditional emulsion polymerization and core-shell emulsion polymerization. It’s core is a kind of acrylate polymer with low degree of crosslinking, and its shell is methyl methacrylate graft copolymer. The modifier of the structure is cross-linked by adding typical crosslinking monomer, so that it’s core has good elasticity. The shell is a high glass temperature polymer, and the particles are easily separated, and can be dispersed evenly to the engineering plastic matrix and interact with engineering plastics. Therefore, the modifier can improve the impact resistance and promote the gel and plasticization of engineering plastics. Improve the toughness of PVC products.

Product Advantages

Excellent Weather Resistance and Anti-Aging Performance

Free of unsaturated double bonds, acrylic rubber within Acrylic Impact Modifier delivers outstanding resistance to ultraviolet radiation and oxidation. It is particularly suitable for products exposed outdoors over the long term, preventing yellowing, chalking and degradation of finished articles.

Superior Processability and Premium Surface Appearance of End Products

Acrylic Impact Modifier features excellent dispersibility and favorable compatibility with plastic substrates. It maintains stable fluidity during processing without migration or die clogging, and is compatible with various forming processes including extrusion and injection molding. Processed PVC profiles and finished goods boast smooth, high-gloss surfaces free of pits, scratches and other defects for superior product aesthetics.

Outstanding Structural Properties and Remarkable Toughening & Impact Resistance

With a composite structure consisting of an elastic core and rigid shell, the modifier markedly improves the impact strength of plastic products. It effectively addresses high brittleness and cracking tendencies of PVC and engineering plastics. Meanwhile, it facilitates resin gelation and plasticization, greatly enhancing the overall toughness and tear resistance of finished products to meet diverse high-strength service conditions.

Quality comparable to top international brands

Our lineup of impact modifiers includes products that match or exceed the quality of renowned brands, such as the Dow Paraloid KM series, Kane Ace FM series, LG IM series, Mitsubishi Metablen W series, Arkema DURASTRENGTH D series, AKDENİZ DMA, and Shandong Rike HL series. For example, LS51 is equivalent to Dow KM-1, Kaneka FM-22, Arkema D-200, LG IM-808, and Baerlocher E-ST 2D, while LS50 corresponds to Dow KM-342, Kaneka FM-50, Arkema D-529, LG IM-812, and Baerlocher E-ST 4.

Application Fields

Outdoor PVC Profile Products

This serves as the core application scenario of our product. Focusing on outdoor PVC articles, the modifier is widely applied to PVC window and door profiles, outdoor decorative profiles, construction PVC structural components and more. Supported by outstanding weather resistance and impact resistance, it effectively prevents embrittlement cracking, aging and strength degradation caused by outdoor sunlight exposure and temperature difference, ensuring long-term stable service of finished products.

General PVC Plastic Products

Suitable for various rigid and semi-rigid general PVC products, including pipes, pipe fittings, sheets, special-shaped profiles and injection-molded accessories. It efficiently remedies the brittleness defect of PVC materials, improves the toughness and impact resistance of finished goods, and elevates production yield.

Modification of Various Engineering Plastics

It is applicable to multiple engineering plastic modification scenarios. The product optimizes substrate plasticization, strengthens interfacial bonding force, and improves material moldability and mechanical properties. Compatible with mainstream molding processes such as injection molding and extrusion, it expands the application scope of engineering plastics.
