  • Teflon is a household name that commonly invokes images of eggs sizzling on a skillet, spatulas flipping pancakes, or rice steaming in a pan.

    But, there is much more to this magical non-stick coating.

    Teflon, a brand name for PTFE (polytetrafluoroethylene), prohibits food from sticking to pots and pans because of its hydrophobic properties.

    As a low-energy, fluorocarbon solid neither water nor water containing substances can influence the surface. This means that nothing will stick to the surface or penetrate it.

    Today, Teflon has improved culinary pursuits and made cooking more accessible, but that isn’t the only field PTFE has influenced.

    The medical device industry would not be what it is today without PTFE. As medical devices work intimately with the human body, they must be completely sanitary, inert, and harmless.

    With its lubriciousness and impenetrable properties, PTFE is used to coat a variety of medical devices such as catheters, surgical equipment, balloons, bladders, and implants.

    But, PTFE only works when the coating itself sticks to the surface. This requires proper surface preparation which can be challenging in any manufacturing floor. It’s especially difficult in medical device manufacturing as specifications are so high and there is no room for failure.    …Read More

  • How Clean is Clean Enough?

    by Emily Walsh May 2017

    Manufacturers often encounter a similar puzzle, when cleaning invisible contaminants from a surface, how do you know when the surface is clean; how clean is clean enough? This is a common question that manufacturers ask when preparing their surfaces for bonding, coating, sealing, printing or painting. Until now, there hasn’t been an objective and reliable way to answer this question. Successfully cleaning a surface directly correlates to the adhesive ability of the surface. In order to get something to stick reliably the surface must be clean. How we define that parameter is different for a variety of materials.

    For example, you clean your car differently than you clean your dishes. Why? Because a car rides on the road through rain, smog, dirt, maybe mud, and the other is a vehicle for your food.

    At BTG Labs, our answer to the “clean enough” question is, “Depends on what you’re doing.” There are dozens of critical surface preparation processes that exist for a number of different applications. A handful include:

    • Flame treatment on polypropylene bumpers prior to painting
    • Plasma treatment on PET catheters prior to coating
    • Hand sanding and solvent wiping on aircraft nut plates before adhesively bonding to composite
    • Grit-blasting titanium golf clubs in preparation of bonding to composite
    • Corona treatment on film for packaging prior to metallization, lamination, or coating

  • The utilization of composites increases daily in manufacturing as more ways in which to use this advanced material are discovered. Composite is a smart material that provides a lighter weight and stronger product. This advanced material is being used in many different industries, from consumer products like bicycle frames to airplanes. Yet, because the strength is held in the fibrous matrix of the material, composites must be adhesively bonded together as traditional mechanical fasteners can break the fibers and compromise the material’s integrity.

    To guarantee these bonds, BTG Labs’ Surface Analyst™ precisely, accurately, and quantifiably measures the surface’s readiness to bond. BTG Labs’ experience in the field of composites reaches back to the genesis of the Surface Analyst when the USAF turned to the company to engineer a hand-held surface energy measurement device for composite bonding of aircraft. Since then, the Surface Analyst’s composite applications continue to increase and span into many more industries.

    Surface Analyst Applications Examples for Bonding, Coating, Sealing, and Painting Composites

    • Aerospace: satellites, aircraft, and spacecraft
    • Sports and Recreation: sporting equipment
    • Automotive: structural components, drive shafts, interior parts
    • Medical Device: prosthetics, repair equipment, tubing
    • Marine: structural frames and components, fiber glass applications
    • Renewable energy: wind turbines, fuel cells, marine turbines, power transmissions, solar panels
    • Construction: architectural, fiberglass, bridges, infrastructure, housing, refurbishing

    AMI Medical Tubing 2016

     

    BTG Labs will host a booth and present at the Applied Marked Information (AMI) Medical Tubing Conference September 13-14, 2016. The event will take place in Crowne Plaza Boston-Woburn, Woburn, Massachusetts. This international event displays the latest in polymeric medical tubing and catheters, covering designs, materials, production and applications. The conference will host discussions on the latest standards and certification requirements. This field of medical device manufacturing is growing and evolving rapidly along with the use of polymers in medical tubing.

    BTG Labs and the Surface Properties of Medical Tubing

     

    BTG Labs will present on the sensitive and complex surface properties of medical tubing such as wettability, adhesion, antithrombogenicity, and biocompatibility. These properties depend on the chemical composition and structure of the uppermost 2-3 nanometers of the material. Thus, monitoring and managing these properties is crucial in manufacturing. This can be challenging as surface monitoring devices such as total reflectance infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS) can be impractical to employ on the manufacturing floor. BTG Labs will discuss the Surface Analyst™ and ways in which it can be utilized to monitor these minute surfaces accurately and sensitively on the factory floor. …Read More
