Expert information, Number 2: Traceability system for high cut resistant gloves

In order to offer our customers an additional quality service, we have developed a unique system of traceability on our highest levels of cut resistant gloves (level 5). This new system is  in most of the critical points similar to the quality system used for CE3 gloves (irreversible effects or mortal danger).

 

This system allows the identification of key parameters in order to trace and to identify at all the stages of the manufacturing process, the source and the yarn batch number used for glove production:

* delivery date of the yarn batch

* technical specifications attached to this specific yarn lot

* date of first and last production made with this lot of yarn

* internal lab test results on gloves knitted with the yarn lot identified previously

In practice, this traceability system appears at the bottom of each textile tag sawn on the glove (see the image). Below the CE information including pictograms and scores, you’ll find a line ‘Batch no.’ followed by a series of both letters and numbers. All the reports related to the batch number written in the textile tag are preciously kept in MIP plant records.

Within its wide range of products, CMIG offers 5 different coating materials for chemical protection gloves to protect the user against chemical risks. The following is a summary about their possible applications:

 

Polyvinylchloride (PVC): This thermoplastic offers high protection against alkalis, salt solutions and a lot of concentrated acids. Many gloves in our PVC range are suitable for HF (hydrofluoric acid). Because of their cost-effectiveness and their robustness gloves made of high quality PVC are still very popular in the chemical industry, predominately for splash protection. 

production of PVC:

Natural rubber (NR): This cost-effective "natural product" offers protection against water based chemical solutions like (non-concentrated) acids, alkalis and salt solutions. Furthermore, concerning splash protection NR can be used in a wide range of applications for different chemicals.

 

Nitrile butadiene rubber (“nitrile”, NBR) or nitrile caoutchouc: This elastomer is best used with oil based chemicals such as solvents, oils and greases, except for many halogenated or aromatic hydrocarbons (in many cases only splash protection). Furthermore, nitrile gloves are suitable for alkaline solutions and not high concentrated acids.

 

Butyl rubber (IIR): This synthetic elastomer is nearly impermeable to gas (used as NBC gloves for military). Gloves made of "butyl" are suited for operations with high concentrated acids (hydrofluoric acid) and alkalis as well as alcohols, saturated salt solutions, glycol ethers, glycerol, hydrogen peroxide and so on. Furthermore, the resistance of "butyl" against solvents like aldehydes, ketones (acetone) and esters is excellent.

 

Viton® or fluor carbon elastomer (FKM): This fluoropolymer elastomer or synthetic rubber shows best protection against the following chemicals: aliphatic (like Pentane), aromatic (like toluene) and halogenated hydrocarbons (like chloroform). Furthermore Viton® offers protection against toxic agents like aniline, PCBs (polychlorinated biphenyls), polychlorinated triphenylene and so on.
