Description:Outline: HL-K355 is a new type acrylic impact modifier which was developed by our R&D center. It is acrylate copolymers and has an core-shell structure, the core is an high-molecular weight acrylic polymer, can improve the impact strength of PVC products, and the shell is methacrylic polymer, can blend with PVC resin, so ACR impact modifier HL-K355 can not only improve the impact strength of PVC products, but improve the surface-gloss of PVC products without damaging its inherent property. Advantage characters: 1) Super-strength impact resistant property 2) Excellent weatherability 3) Excellent processability 4) Ensuring the stability of size of the finished products 5) Widening processing range Technical specifications: 1) Appearance: white powder 2) Sieve residue (0.45mm) (%): ≤2.0 3) Volatile contents (%): ≤1.0 4) Bulk density (g/cm3): 0.38-0.5 5) Izod impact strength (kJ/m, 20°C): 26.3 (condition: keep 0°C for 24 hour) 6) Tensile strength (MPa): 46.1 (condition: keep 18°C for 24 hour) 7) Vicat softening point (condition: 4.9kg load) (°C): 84.9 Remarks: 1.
