EXL‑2390 is a high‑performance all‑acrylic core‑shell impact modifier specifically designed for PC and PC/ABS alloy modification. With optimized rubber core and hard acrylic shell microstructure, this toughening agent achieves outstanding dispersion within polycarbonate‑based matrix during twin‑screw extrusion. It effectively elevates room‑temperature and low‑temperature notch impact strength, while minimizing negative influence on modulus, heat‑resistance and weather‑aging property of finished

Product Detail

Product Detail PageChemical IdentityEXL‑2390 is manufactured via emulsion polymerization to form structured acrylic core‑shell particles. The cross‑linked flexible acrylate rubber core serves as the energy‑absorbing phase, whereas the rigid PMMA outer shell ensures favorable interfacial bonding with PC and PC/ABS polymer matrices. Thanks to tailored particle‑size distribution, the powder‑form modifier disperses uniformly throughout the polycarbonate alloy melt under typical compounding temperatures. No extra premixing or pre‑grinding procedure is required before extrusion. The core‑shell structure maintains its integrity under high processing temperature and shear, avoiding rubber‑phase coalescence inside the finished plastic articles.

Key PerformanceThe elastic inner core dissipates fracture energy efficiently upon mechanical shock, suppressing crack initiation and crack propagation within PC and PC/ABS alloys. EXL‑2390 significantly upgrades notched‑Izod impact values at both ambient and low‑temperature conditions. Compared with conventional butadiene‑based rubber modifiers, this acrylic core‑shell grade provides superior UV resistance and long‑term weathering stability, which reduces yellowing risk for outdoor plastic parts. It retains good flexural modulus and heat‑deflection temperature after incorporation into PC‑based formulations. In addition, it shows acceptable influence on melt‑flow property, so that injection‑molding processability of modified PC‑ABS compounds remains suitable for mass production.

ApplicationsPrimary usage focuses on impact modification for neat PC, glass‑filled PC, as well as PC/ABS alloy systems. It is widely adopted for compounding outdoor electronic housings, automotive exterior and interior plastic parts, appliance structural components and industrial equipment plastic enclosures. EXL‑2390 fits formulations that demand balanced toughness, rigidity and anti‑aging performance. It is suitable for halogen‑free engineering plastic grades used in electrical and electronic industry. The modified PC‑ABS compounds can go through standard injection‑molding process for manufacturing high‑quality finished components exposed to sunlight and variable temperature environments.

Storage & HandlingStore EXL‑2390 in sealed original packaging inside cool, dry and ventilated warehouse. The recommended storage temperature range is 10‑30℃. Prevent direct sunlight, high‑humidity condition and heat sources to avoid powder caking. Anti‑static protection is necessary during discharging, conveying and feeding operations in compounding workshops. Once the bag is opened, consume the material promptly to prevent moisture absorption. Do not stack pallets excessively high; heavy compression may trigger agglomeration of fine particles.

Why Choose SupplierWe provide stable‑quality alternative grade of EXL‑2390 acrylic core‑shell toughener for engineering‑plastic compound manufacturers. Complete TDS and MSDS documentation are prepared for export business. Both large bulk container shipment and small trial‑order quantities are supported. This toughening additive helps overseas compound plants to develop weather‑resistant high‑toughness PC and PC/ABS alloy formulations for automotive, electronics and outdoor industrial end‑markets.
