Radiation Chemistry Rules: Crystalline vs Amorphous Polymer Structures

amorphous polymer structures
A question we are often asked is “How are the polymers in my product going to respond to irradiation.” The answer is . . . not short, so we will have to answer it in multiple entries.

Sun, Sand, and Polymers: NPE 2018

E-Beam NPE 2018Though the show doesn’t officially start until Monday, the E-BEAM team has made their way down to the sunshine state to start prepping the booth (and do a little fishing while they can…).

Located at the Orange County Convention Center in Orlando, Florida, the NPE officially goes into full swing on Monday morning and will continue throughout the week. This year, the show boasts 65,000+ professionals from 128 different countries and covers the full spectrum of the plastics industry.

E-BEAM does Boston (BIOMEDevice Boston, that is)

BIOMEDevice BostonThis April will find the E-BEAM team enjoying all Boston has to offer: walking the Freedom Trail, checking out Fenway Park, and of course too many (is there such a thing?) cannoli at Mike’s Pastry.

And one more thing: the BIOMEDevice Boston show, on April 18th-19th.

Crash Course Recap: Crosslinkable Polymers

The last E-BEAM Crash Course tackled the subject of crosslinkable polymers. But just what are crosslinkable polymers?

Ionizing radiation produced by the electron beam breaks bonds within the molecules of the polymers. With some polymers, these bonds reform in a beneficial way, which we call crosslinking. For example, polyethylene is a polymer that is relatively easy to crosslink (if you have an electron beam, that is 😉 ). In the polyethylene crosslinking process, a hydrogen atom is broken, allowing the carbon  backbone of the molecule to bond with the carbon backbone of an adjacent molecule. This imparts beneficial properties like: better abrasion resistance, less permeability, higher operating temperatures, and the ability to instantly know the winning numbers for the next jackpot lottery.

Crash Course Recap: The 4 Steps to Sterilization Validation

E-BEAM’s latest Crash Course walks the viewer through a quick overview of the four main steps to sterilization validation.

To be able to officially declare your medical device as sterile after processing, you must first perform a sterilization validation. Radiation sterilization methods, like e-beam, are monitored by the ISO 11137 standard. But don’t worry, both your sterilization provider and microbiology lab will help walk you through it!

E-BEAM Services adds a second accelerator in Cranbury, New Jersey

Cranbury, New Jersey – January 2018

E-BEAM Services, Inc. has announced a major addition to its electron beam sterilization capacity with a second high-powered electron beam accelerator in Cranbury, New Jersey. This accelerator is specially designed to serve the rapidly growing demand for electron beam sterilization in the medical device and pharmaceutical industries.

This addition is timely, according to E-BEAM’s Director of Business Development, Bill Crilley, “because the number of medical devices and pharmaceuticals being validated for ISO/FDA compliant sterilization is at an all-time high for E-BEAM Services.” Read More »

What is a dose map and how much does it cost?

A dose map, or dose distribution study, helps us determine if all of the product within your case is receiving the necessary sterilization dose. In this study, we take a measurement of the internal doses throughout a case of product.

The case of product is opened by E-BEAM Services, and our trained lab technicians place dosimeters at multiple locations, based on guidance provided in ISO 11137-3. We then run the case through the accelerator in a simulated production scenario, taking an additional measurement of the surface (or surfaces, in two-sided processing) of the case that faces the beam. Once the processing is complete, we read the dosimeters, using the surface reading as a reference dose. We identify the location of the minimum and maximum internal doses within the case, and then relate those to the surface dose using simple ratios. Read More »

Dear Karen: How many samples do I need for an e-beam material test?

 

Dear Karen,

I am a new startup company, and am trying to get my product validated for e-beam sterilization. How many samples do I need to send you for the material test? And, while we’re talking about material tests….what are they?

Sincerely,

Material Girl Read More »
