You will find below Ansell’s answers to frequently asked questions about glove selection and glove use.
Please feel free to ask Ansell any other general or technical question. We will make sure you will be answered adequately as soon as possible.
Need an 8.5 or a 9? Check out your optimal glove size!Ansell has developed a handy glove-sizing chart for glove wearers who are in doubt about the size of gloves they need. The chart is a simple drawing of a hand, with lines indicating the glove sizes. Just place your right hand palm down on the figure, with your fingers together and read off your size!
For the chemicals I'm handling, how do I select the right glove?For each of our chemical resistant gloves, we have performed tests at certified laboratories, and we can provide you with these data on demand. When you want to choose the appropriate glove for your application, you can make a selection with the Ansell Specware CD-Rom or online on our website. Don't hesitate to contact our Technical Department for more information on chemical permeation dates and glove suitability.
I have an allergy towards natural rubber proteins, and I need a glove with good dexterity. Which disposable glove can I use?We have disposable gloves which are free of any presence of latex proteins, because they are made of synthetic materials. Touch N Tuff or Dura-Touch can be used without any risk of latex allergy.
I need a Barrier glove for use with certain chemicals, but I also need dexterity in my work. How can I combine?For some chemicals, only Barrier provides enough protection. Since Barrier is a glove made of two thin films welded together, dexterity is not optimal. However, workers tend to wear a disposable glove like Touch N Tuff above the Barrier glove. Due to this 'double donning', a better fitting of the glove on the hand is achieved. Depending on the situation and the protection needed, a Sol-Vex or a general purpose glove can be worn over the Barrier glove.
I need a silicone-free disposable glove. What can you recommend?Our Gammex and Conform + gloves (both natural rubber), Touch N Tuff (nitrile rubber) and Dura-Touch (vinyl) are free of silicones.
What kind of chemical protective glove materials do you offer, and why are there so many different materials?Ansell offers a wide range of gloves in different materials. Each material has its own properties, strengths and weaknesses. Natural rubber or latex is a natural product, coming from the Hevea Brasiliensis tree and is well appreciated for its flexibility and comfort. Nitrile rubber and neoprene are synthetic rubbers, thus man-made. PVC and PVA are plastics and also man-made. Barrier is a laminated film material and highly chemical resistant.
Where can I find more information about testing procedures and pictograms?You can download the 'EN guide' or 'Testing Guide' on this website (Acrobat Reader file), to have a brief overview of European Standards and test procedures. If you need more information about technical issues, please contact the Ansell Technical Department.
Which glove do you recommend for working in plating solutions, such as gold, silver, nickel, ...?We recommend a Sol-Vex glove and most users prefer the longer version 37-185, to protect the forearm.
Which gloves can be autoclaved with water at a temperature of 120°C?All chemical resistant gloves made of natural rubber, nitrile rubber and neoprene can be autoclaved. Note that PVC and PVA will melt at these elevated temperatures, and can not be sterilized with this method.
Why can I not use vinyl gloves for contact with fatty foodstuffs?The plasticizers in the formulation of PVC have a tendency to migrate into food. Tests have shown that for fatty foodstuffs, this migration level is higher than allowed in European Directives. This is the reason why we definitely advise against using vinyl gloves for contact with fatty foods. Our nitrile proFood 92-465 gloves are recommended for these applications and are suitable for contact with all foods.
Why do I have to change the glove, even if there is no visual damage at the outside?A glove that has been in contact with chemicals, is not necessarily degraded. The chemical however can and will permeate through the glove material. When a glove is worn during a certain period, then removed from the hand, the chemical continues its way through the glove. It could be that this glove is contaminated at the inside when it is put on several hours or minutes later, and physical damage did not occur.
