Polysciences, Inc. Polyethylenimine, Branched, MW 2,000 (bPEI 2,000), 500 g | 9002-98-6
Branched Polyethylenimine, MW ~2,000 (bPEI 2000) is a colorless to yellowish liquid. It is a water-soluble polyamine with high cationic charge density. bPEI 2000 contains primary, secondary, and tertiary amine groups in approximately 40/36/24 ratio.Industrially, branched polyethylenimine (bPEI) because of their high charge density adsorb strongly on negatively charged surfaces such as cellulose, polyester, polyamides, metals, etc. bPEIs have extensive applications as an auxiliary agent intensifying manufacturing processes and improving quality of the final products. They are widely used in: paper-making, water treatment, detergents, adhesives, and cosmetics.RESIN CONTENT (WT%): ≥ 99CHARGE DENSITY (CATIONIC): 16 meq/g

BEZWADA BIOMEDICAL LLC Poly (caprolactone-co-glycolide), caprolactone:glycolide 95:5 , viscosity 1.0 to 2.0 dl/g, 5.0 GM
The presence of caprolactone repeat units helps in reducing the hardness and toughness of pure polyglycolide polymer and helps in decreasing the hydrolytic degradation rates of polyglycolide homopolymer due to the presence of extended alkyl chain/hydrophobicity of caprolactone. The polymers are used in medical device, drug delivery and 3D printing.

BEZWADA BIOMEDICAL LLC Poly(glycolide-co-caprolactone), Glycolide:caprolactone 75:25, viscosity 1.4 to 2.0 dl/g, 5.0 GM
Copolymers of glycolide with caprolactone have been developed to reduce the stiffness and increase the absorption time of the polymer. These copolymers have found numerous applications in medical device and controlled drug delivery applications.
BEZWADA BIOMEDICAL LLC Poly(glycolide-co-caprolactone), Glycolide:caprolactone 60:40, viscosity 1.2 to 2.0 dl/g, 5.0 GM
Copolymers of glycolide with caprolactone have been developed to reduce the stiffness and increase the absorption time of the polymer. These copolymers have found numerous applications in medical device and controlled drug delivery applications.
BEZWADA BIOMEDICAL LLC Poly(P-dioxanone-co-L-lactide), p-dioxanone:L-lactide 90:10, viscosity 1.5 to 2.5 dl/g, 5.0 GM
Copolymers of PDS with L-lactide is soft and flexible and has exellent pliability. Biomedical devices include surgical sutures, staples, meshes, and controlled drug delivery.BSR profile longer than PDS.Biomedical devices include surgical sutures, staples, meshes, and controlled drug delivery.
BEZWADA BIOMEDICAL LLC Poly(caprolactone-co-L-lactide) caprolactone:L-lactide 85:15, viscosity 1.0 to 2.0 dl/g, 5.0 GM
The presence of lactide repeat units in the copolymer reduces the degree of close packing between caprolactone repeat units leaving the polymer with nice elastic properties while maintaining a relatively slow degradation profile. This allows PCL-PLA copolymers to be used in drug delivery (liquid polymers) and medical device coatings.
BEZWADA BIOMEDICAL LLC Poly(D,L-lactide-co-glycolide), D,L-lactide:glycolide 75:25, viscosity 0.55 to 0.75 dL/g, 5.0 GM
In order to decrease the absorption times of implantable devices incorporating L(-)-lactide, copolymers of L(-)-lactide and dl-lactide with glycolide have been prepared. The polymers are used in medical devices and drug delivery.
