Product Description

Product Description:

PTMC Poly(trimethene carbonate) - Product Overview

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.

Welcome to the world of Special Chemicals, where we specialize in providing top-quality, cutting-edge chemicals for a variety of applications. Our latest product, microcapsules for injection, is a revolutionary development in the field of biodegradable materials. With its unique properties and exceptional quality, it has quickly become a top choice for many industries.

Our microcapsules for injection are made from a special chemical compound with a molecular weight (MW) range of 10000 to 500000. This ensures a high level of stability and durability, making it suitable for a wide range of applications. The appearance of our product is in the form of white or pale yellow particles, which makes it easy to identify and use.

One of the key benefits of our microcapsules for injection is its low heavy metal content, with a concentration of less than 10 parts per million (ppm). This makes it a safe and non-toxic option for use in various industries. It also makes our product eco-friendly and suitable for environmentally-conscious companies.

Our microcapsules for injection are primarily used as a degradable polymer material and biomedical polymer. Its inherent viscosity, ranging from 0.1 to 7.0 DL/g, makes it ideal for slow release and drug delivery applications. The slow release feature ensures a sustained and controlled release of the encapsulated substance, making it perfect for medical and pharmaceutical use.

Our product is highly versatile and can be used in a variety of industries, such as pharmaceuticals, cosmetics, and food. Its biodegradable nature makes it an attractive choice for companies looking for sustainable and environmentally-friendly solutions.

In summary, Special Chemicals' microcapsules for injection are a game-changing product in the field of biodegradable materials. With its unique properties, such as slow release, drug delivery, and non-toxicity, it offers a wide range of applications in various industries. We are committed to providing top-quality, eco-friendly solutions to our clients, and our microcapsules for injection are a testament to that commitment. Choose Special Chemicals for your chemical needs and experience the difference!

Product Applications:
1. Drug Delivery

PTMC is widely used in drug delivery systems due to its biodegradable nature and excellent biocompatibility. The polymer can be formulated into various drug carriers, such as nanoparticles, microspheres, and hydrogels, to effectively deliver drugs to targeted sites in the body. This controlled drug release system helps to reduce the frequency of dosing and minimize potential side effects.

2. Medical Implants

PTMC is commonly used in the production of medical implants, such as screws, plates, and scaffolds. Its biodegradable nature allows the implant to gradually degrade and be replaced by natural tissues as the body heals. This eliminates the need for a second surgery to remove the implant, reducing the risk of complications and improving patient outcomes.

3. Tissue Engineering

PTMC is also used in tissue engineering applications, where it can serve as a scaffold to support the growth of new tissues. The polymer's porous structure allows for the infiltration of cells and nutrients, promoting tissue regeneration. Additionally, as the PTMC degrades, it releases lactic acid, which can stimulate the growth of blood vessels and aid in tissue repair.

Product Benefits:
  • No harm and toxic side effects: PTMC is a biocompatible and biodegradable polymer that does not cause any harm or toxic side effects to the body.
  • Environmentally friendly: Since PTMC is biodegradable, it does not contribute to environmental pollution and is a sustainable option for medical applications.
  • Wide range of biomedical applications: PTMC can be used in various biomedical applications, such as drug delivery, medical implants, and tissue engineering.
  • Controlled drug release: PTMC's controlled drug release system allows for a more efficient and targeted delivery of drugs.
  • Enhanced tissue regeneration: PTMC can stimulate the growth of blood vessels and promote tissue regeneration, leading to better healing outcomes.
