Plastic Selection in medical device: A guide for manufacturers

As a plastic expert in the medical device industry, I've seen firsthand how critical material selection is when it comes to designing and manufacturing safe and effective products. The plastics used must meet the requirements of its intended use and the Medical Device Regulation (MDR), which places strict standards on the safety and efficacy of medical devices. The below requiremetns should give guidance to help manufacturers better understand why plastic selection matters, and how to make the right choices for their products.

Biocompatibility??

Biocompatibility is a critical consideration when selecting materials for medical grade plastics. The ISO 10993 standard provides a framework for evaluating the biocompatibility of medical devices, including guidance for the most critical step the biocompatibility risk assessment. It's essential to choose materials that are biocompatible and won't cause adverse reactions or harm to patients. To assure the biocompatibility chemical and biological tests can be performed such as extractables and leachable or cytotoxicity tests.

Sterilization??

If your medical products must be sterilized, it is crucial to ensure that sterilization method and the plastic selected are compatible. Different sterilization methods can impact the properties of medical grade plastics, so it's essential to choose materials that can withstand the necessary sterilization processes without degrading. Manufacturers should consider factors such as dose, temperature, humidity, and exposure time when selecting materials for their products.

Durability??

Manufacturers should choose materials that are appropriate for the intended use of the product, whether that's for single-use or multiple-use products. Medical products must be durable and long-lasting to ensure that they can withstand the rigors of use and transport. Materials should be able to maintain their properties over their lifetime and resist damage from physical stress or chemical exposure.

Material Compliance??

Finally, when selecting materials for medical grade plastics, it's essential to consider regulatory compliance. In Europe, medical grade plastics must meet the requirements of the Medical Device Regulation (MDR), which places strict standards on the safety and efficacy of medical devices. Manufacturers must select materials that comply with the MDR and any other relevant regulations or guidelines such as REACH.

Sustainability??

Sustainability is an increasingly important consideration in all industries. Manufacturers should choose materials that are eco-friendly and can be recycled or disposed of safely. They should also consider the carbon footprint of their products and aim to reduce hazardous substances such as phthalates as much as possible. Choosing sustainable materials can help reduce the environmental impact of medical grade plastics and promote a more sustainable future.

Conclusion??

Material selection is a critical aspect of designing and manufacturing safe, effective, and sustainable medical devices in Europe. By considering factors such as biocompatibility, sterilization, durability, sustainability, and regulatory compliance, Gradical helps you to find the right plastic for your application.
