产品特性：

PMMA微球，即聚甲基丙烯酸酯微球，简称为丙烯酸酯微球。PMMA聚合物是无定型、透明和无色的热塑型聚合物，坚硬耐压。它具有优良的耐磨和耐紫外光照射，以及出色的透光性。它的疏水性比聚苯乙烯弱，因此具有较低的蛋白和多肽吸附性。它的比重为1.19 g/ml，高于聚苯乙烯，更易于沉降或离心分离。其表面通常携带亲水的阴离子，折光系数为1.48.

Product Introduction:

PMMA microspheres, that is, polymethacrylate microspheres, referred to as acrylate microspheres. PMMA polymer is an amorphous, transparent and colorless thermoplastic polymer that is hard and pressure resistant. It has excellent abrasion and UV resistance, as well as excellent light transmission. It is less hydrophobic than polystyrene and therefore has lower protein and peptide adsorption. It has a specific gravity of 1.19 g/ml, which is higher than polystyrene and is easier to settle or centrifuge. Its surface usually carries a hydrophilic anion with a refractive index of 1.48.

PMMA具有良好的生物相容性，因此，被广泛应用于许多医学和生物医学领域，胶体晶体，和可注射的皮肤填充物

PMMA has good biocompatibility and is therefore widely used in many medical and biomedical fields, colloidal crystals, and injectable skin fillers.
