Medical plastics are revolutionizing the health care industry. Equipment that has previously been made of steel, ceramic or glass is now being made of this durable, cost-effective material. There are even several patient treatment methods that now involve medical plastic. Let’s learn more about medical-grade plastics and the incredible advantages they offer the industry.
What Is Medical Grade Plastic?
The term “medical grade” means that the products, whatever they may be, come from a seller who operates under a physician’s license. In the case of a medical plastics manufacturer, this means a medical director is present to supervise and regulate the materials used to fabricate the equipment.
Medical plastic itself is designed to be temperature, chemical, and corrosion-resistant. That way, it can handle frequent sterilization cycles and any other medical or bodily fluids it comes into contact with. Medical grade polypropylene and medical-grade polycarbonate are two common polymers used in several applications, from MRI casings to surgical tools.
Preparation of plastic medical equipment requirements as a medical device product. The primary requirement is the safety and effectiveness of the product. But also the effectiveness of product safety must be guaranteed based on valid. The safety of medical plastic products mainly for handling the product is safe, health care workers, patients, and the product after use. To meet the security requirements of plastic medical devices. We should consider many go from product design, selection of raw materials, production technology. And production, and processing of plastic medical products. The production environment, product quality, and technical indicators meet the requirements, and so on.
With a better understanding of medical-grade plastics in mind, let’s explore a few advantages they have to offer the health care industry.
Compared with ordinary plastics, medical grade plastic is higher
(1) Since most toxic monomers and oligomers. Therefore medical plastics have strict limits on residues of these substances.
(2) Plastic in the polymerization process will inevitably be exposed to the reaction vessel, the metal catalyst, etc. According to the medical plastics national standard, zinc, lead, cadmium, copper, barium, tin, often contain trace amounts of metal ions. And other metal ions residue situation It is clearly defined.
(3)For medical plastics require a higher purity, narrow molecular weight distribution.
(4) The plastic processing or modification process requires the addition of various additives. Such as the amount of plasticizer in PVC medical products is often as high as 30-60%. Thus requiring far as possible using non-toxic chemicals. To prevent long-term use or reduce the precipitation of additives. So as not to affect product performance and treatment.
(5) According to the requirements of medical plastic. Often need to make products having a hydrophilic surface,anti-coagulation. Anti-radiation sterilization, and other functions.
