Overview of Medical Polymers

Definition: Thermoplastics play a critical role in modern medical devices.  Amorphous and crystalline thermoplastics offer distinct performance properties.  Within these categories are a variety of specific polymers suitable for a wide range of device components. Purpose: An overview of amorphous and crystalline thermoplastics, along with specific examples and attributes for each category. View Presentation

Color Additives for Medical Device Plastics

Definition: Pre-color compounds and color concentrates for medical applications are most commonly manufactured using two categories of color additives: FDA Food Contact Pigments, and FDA Medical Device Pigments.  The selection of one pigment classification over the other may affect the FDA approval process for medical devices. Purpose: Selection of pigments suitable for medical device plastics View Presentation

Polymer Compounding Basics

Definition: Upgrading or adding value of polymers or polymer systems through melt blending & mixing of additives into a polymer matrix or melt mixing two or more polymers together to make an alloy Purpose: Tailor properties to satisfy a specific applications requirements View Presentation
