  1. Understanding Drawn Fiber: Polymers, Process, And Properties
    3/16/2018

    Drawn fiber is an improved performance monofilament based on extrusion technology and found in a wide array of applications such as over-braiding for hoses, weaves as mist eliminators, medical braiding, instrument and racquet string, and strengthening for industrial belting applications. 

  2. Sutures And AEOS ePTFE Monofilament
    3/16/2018

    One of the most successful synthetic materials with suture applications has been PTFE and its variant, expanded PTFE (ePTFE). ZEUS now offers Aeos ePTFE suture monofilament for safe and effective surgical interventions while being readily obtainable for non-exclusive or unbranded use.

  3. Sterilize Bioabsorbable Medical Devices With Vaporized Peracetic Acid
    8/25/2017

    This report explains how the innovative usage of vaporized peracetic acid (VPA) provides a safe, reliable, and versatile method for sterilizing bioabsorbable implants.

  4. Bioabsorbable Materials 101
    8/15/2017

    There are a wide variety of materials to choose from when it comes to micro medical components. In this article, MTD Micro Molding answers some of the most commonly asked questions about bioabsorbables.

  5. Keys To Bioabsorbable Process Development: Consistency And Control
    3/8/2017

    A medical device company developed a bioabsorbable fixation design and concept that was commended by many surgeons in the industry. Unfortunately, after several years of working with a reputable molder, there was limited consistency and success in producing the part that was in their original drawings. MTD assisted the company by guiding them through material characterization and the development of a unique tooling construction concept to reduce secondary operations. MTD’s micromolded parts achieved minimal and consistent IV loss and were much more consistent shot to shot.

  6. Introduction To Liquid Crystal Polymers
    8/23/2016

    Liquid polymer crystals are important in day to day use, especially in medical device fields and applications. This article introduces liquid crystal polymers and discusses their origin, structures, behaviors, and uses in thermoplastics and fibers with potentially broad applications.

  7. Innovative Uses Of Ethylene Vinyl Acetate Polymers For Advancing Healthcare

    Ethylene vinyl acetate (EVA) has a long and successful history of innovation in medical packaging, medical devices, and pharmaceutical applications. By Jose D. Reyes, Celanese Corporation

  8. Liquid Silicone Rubber Takes The Heat
    11/10/2014

    Unlike thermoplastics, which soften when heated, liquid silicone rubber (LSR) is created in high heat and can easily withstand high-heat applications.. This article discusses the merits of LSR, a comparison between thermoplastics and thermosets, and design considerations for LSR parts.

  9. Res Solutions: Selecting The Right Materials For Your Parts
    2/7/2014

    There are more than 85,000 options for plastic materials listed in materials databases, and within those, there are 45 polymer families, which can be broadly classified into two categories: thermosets and thermoplastics. With a primary focus on the latter, this discussion offers some insight into material selection and common applications.

  10. Effects Of Sterilization Methods On Key Properties Of Specialty Optical Fibers Used In Medical Devices
    8/13/2013

    Optical fibers with different types of polymer coatings were exposed to three sterilization conditions: multiple autoclaving, treatment with ethylene oxide and treatment with gamma rays. Effects of different sterilization techniques on key optical and mechanical properties of the fibers are reported. The primary attention is given to behavior of the coatings in harsh sterilization environments. The following four coating/buffer types were investigated: (i) dual acrylate, (ii) polyimide, (iii) silicone/PEEK and (iv) fluoroacrylate hard cladding/ETFE.
