Poly(trimethylene carbonate)Usage

PTMC has good biocompatibility and biodegradability.

Under the body temperature, the rubber has a certain elasticity, which is widely used in the degradation of the binding device, drug controlled release material, in vivo implantation materials and in vivo supporting materials, etc.

The properties of the polymer can be improved by co polymerization with poly lactic acid.

Poly(trimethylene carbonate)Packaging and Shipping

Packing: 1kg/bag or 25kg/drum

Poly(trimethylene carbonate)Storage

1.In order to ensure product quality,a special package to aviod water is neccessary.

2.We filled high qurity dry nitorgen in the Polyethylene bag for hot plastic, the outer lining of thermal plastic foil pouch, built-in desiccant. All the packing is done in a highly clean room.

3.All of the polymers should be stored at 0 ° C or less, and should prevent hydrolysis. Before opening, the product should be allowed to adjust to room temperature to avoid condensation polymer concentrate combined with moisture in the bag. To re-opened after the product packaging sealing, must be of high purity dry nitrogen filled to prevent moisture generated in the bag.
