Plastics are ubiquitous a material as they come, and there is nary an industry that does not utilize them in an adhesion application; medical device, automotive, aerospace, consumer goods, and flexible film and packaging industries all exploit the versatility of polymers in manufacturing. Take a closer look at medical device and automotive industries and you’ll find that the same polypropylene used to make car bumpers in the automotive is also used to make life-saving implantable medical devices.
Polymers are generally chemically stable materials. While this is a desirable quality for other purposes, it is the industry's greatest challenge to overcome for adhesion applications (coating, bonding, printing, priming and painting). In order for these materials to adhere successfully they have to undergo some type of surface activation process, like plasma treatment. This process will impart chemically reactive groups on the surface and increase chemical reactivity. This reactivity is a quantifiable material property called surface energy. Plasma treatment is a convenient, cost effective means of achieving surface activation of polymers. Before the plasma treatment can accomplish the proper activation of the surface, the chemistry of the polymer must be considered.
This week BTG Labs and Plasmatreat got together to co-present a webinar that de-mystifies plasma treatment as it relates to polymer chemistry.
Understanding surface state at each manufacturing step will allow you to gain complete control over your surface treatment and bonding operation. Here at BTG Labs, we provide a process control check that quantifies that surface state with a simple number.
Control the process, control the number, control the product.
