The company offers full-cycle solutions for polymer materials, integrating advanced synthesis technologies with application-specific engineering. For polyolefins, gas-phase fluidized bed reactors are employed to produce PE grades with melt indices ranging from 0.1 to 500 g/10 min, suitable for film blowing, pipe extrusion, and rotational molding. Specialized Ziegler-Natta catalysts enable precise control of PP isotacticity (95-99%), yielding products with flexural moduli up to 1800 MPa for rigid packaging applications. In elastomer fields, solution polymerization processes are used to create SBS (styrene-butadiene-styrene) block copolymers with tailored glass transition temperatures (-70°C to +100°C) for adhesive and sealant formulations. The company's R&D team supports clients in material prototyping, utilizing 3D printing with polymer pellets to validate part designs prior to full-scale production. Life cycle assessment (LCA) services are provided to optimize recycling processes, such as the chemical depolymerization of PET into monoethylene glycol for closed-loop reuse.
