STANDARDS

[/vc_column_text][vc_column_text]All COFRA’s gloves are engineered to grant protection to workers, in the foreseeable conditions of end use. The performances of PPE are expressed by a pictogram alongside the markings. They are certified according to laboratory tests.

EN 420:2003+A1:2009 – Protective gloves – General requirements and test methods
It defines the requirements for glove design and construction, innocuousness, sizes, dexterity and marking. The compliance with EN 420:2003+A1:2009 is compulsory for any kind of gloves, however marking is not strictly required. Any further technical information is in the information sheet included in the packaging.
DEXTERITY
Dexterity is the the capacity to handle tools and make movements when wearing gloves. According to the intended use, the glove should provide the maximum dexterity allowed. It depends on several factors, e.g. the thickness of the glove material, its elasticity, its deformability. COFRA carries out the dexterity test on each glove, so that the best application can be selected. EN 420:2003+A1:2009 standard defines different performance degrees in a range from 1 (low dexterity) up to maximum 5 (maximum dexterity).
06 Art. LIMBER (dexterity 5), it allows to handle with high precision even very small tools

European food contact regulations
Normativa-Alimentare The products intended to be in direct contact with food must bear the symbol “glass and fork”, complying with EC no.1935/2004 regulation (“Materials and items intended to come in contact with food”) and especially the gloves have to comply with the more specific EU no.10/2011 Regulation (“Plastic materials and items intended to come in contact with food”). This means that all the materials used to manufacture gloves must not pose a danger to human health and they must not cause any change in the composition or a deterioration of foodstuffs. For this purpose the foodstuffs are classified into 5 groups and the compliance of gloves in contact with any of them is tested. Therefore a glove can be suitable for the contact with some groups of food and not suitable for others. For correct information about the kinds of food for any glove, the manufacturing companies must issue information through the Declaration of Conformity.
OEKO-TEX®
OEKO-TEX OEKO-TEX® is a voluntary certification of product through which the certified company commits itself to keep in time the safeness of its own products. The OEKO-TEX® 100 mark guarantees that the textiles (or accessories of the textiles, metallic ones included) do not contain or release harmful substances for the consumer (pesticides, heavy metals, formaldehyde, aromatic amines, allergyinducing dyestuffs and so on). OEKO-TEX® certified gloves fully comply with the requirements of standard EN 420:2003+A1:2009 and they abide by the requirements of the attachment XVII of REACH (regulation 552:2009) having the textile product as area of pertinence.
REACH
00 In order to safeguard the consumers’ health, the European Union issued the REACH regulation (come into force on 1st June 2007) which forbids the use of certain chemicals. COFRA guarantees that all its gloves comply with the REACH regulation; they do not contain forbidden or limited substances (Aromatic amines and 4-aminobenzoic acid deriving from azo dyes, heavy metals, phthalates, and so on) and, to guarantee it, all garments and accessories used during production are subjected to controls.

THE COATING

[/vc_column_text][vc_column_text]

The kind of coating is essential to choose the right glove: it has to be chosen according to the different contact surfaces, mechanical performance demands, comfort needs:
 GRANITICK-tr-ico Nitrile compound able to reach more advanced results on the abrasion resistance and mechanical stress than the nitrile coated gloves presently on the market. It guarantees an abrasion resistance notably greater than a normal nitrile coating. The result is a longer lifetime of gloves, thus allowing applications in harder work environments. Tear and perforation resistance are improved, too. The thickness of GRANITICK is innovative, too: notwithstanding the superior mechanical performance, it is a compound thinner than usual, thus assuring adherence to hand and maximum dexterity. The typical features of nitrile are the same as high quality nitrile, with a good resistance to fats and oils and with good grip on dry surfaces.

NITRA-X-tr-ico

Innovative compound developed by COFRA that guarantees optimal flexibility. The special porosity provides a superb grip on wet and oily surfaces. Good level of breathability. Recommended for humid and/or oily surfaces, but also for works requiring a new level of comfort while always keeping the mechanical performances of a nitrile glove.

SMOOTH
NITRILE

Excellent grip on dry surfaces. Resistant to oils and chemicals. The compact surface provides optimal mechanical properties and it opposes to water leaking. Coating suitable for different applications.

NITRILE FOAM

Excellent grip on dry and wet surfaces. The porous surface provides excellent breathability and comfort, as well as better flexibility than smooth nitrile. Coating suitable for different applications, above all wet surfaces.

SAND FINISHED NITRILE

Excellent grip on oily surfaces, thanks to its special coating. Very good performance in durability, abrasion and tear. Recommended for workshops and oily tools handling.

PU-DEX-tr-ico

New polyurethane compound that turns around the concept of grip. The excellent grasp of little tools and the maximum dexterity enhance productivity in those jobs where maximum precision and accuracy are demanded.

POLYURETHANE

Superb breathability. Its thinness and flexibility provide maximum dexterity and superb comfort. It is not well resistant to wear. Recommended for little tools handling and in applications where a high mechanical resistance is not demanded.

NITRILE MIXED POLYURETHANE

Excellent breathability, flexibility and dexterity. The nitrile strengthens the glove, thus enhancing its mechanical resistance. Recommended for little tools handling or in applications that demand increased breathability.

CRINKLED LATEX

Excellent grip on dry surfaces. Maximum comfort and dexterity provided from the elasticity of latex. Not resistant to oils and chemicals in general. Recommended for construction and high comfort demand.

NEOPRENE

Strong and durable, it provides excellent protection from physical hazards such as cuts and abrasions, great resistance and chemical protection. This coating is resistant to degradation by ozone, sunlight and oxidation. Finally, it remains functional and fl exible at both low and at high temperatures.

[/vc_column_text][vc_column_text]

THE LININGS

[/vc_column_text][vc_column_text]

NYLON

It is the fabric offering the best resistance to abrasion and wear, far better than polyester. It resists also to oils and most of chemicals. Good elasticity.

POLYESTER

Fabric which combines good mechanical properties (wear resistance and dimensional steadiness) and good thermic properties. Lightness and robustness at the same time make it very versatile.

COTTON

It is the most comfortable fabric to the skin. Less resistant than nylon, it is however highly breathable.

ACRYLIC

It provides excellent thermal insulation, above all if flock-lined. Good abrasion resistance. Recommended for work at low temperatures.

DuPont™ Kevlar®

Highly cut, flame and heat resistant aramidic yarn. Reinforced with a flexible steel mesh, it can reach the maximum cut protection category (category 5). DuPont ™ and Kevlar® are trademarks or registered trademarks of E.I. du Pont de Nemours and Company.

HDPE
(high density polyethylene)

Highly cut protection yarn. Thin and flexible, it provides protection, comfort and superb dexterity.

UHMWPE
(Ultra High Molecular Weight Poly-Ethylene)

The ultra-high-molecular-weight polyethylene is a high-tech material, belonging to the same chemical group of HDPE, in respect of which it has an enhanced mechanical performance thanks to a very high molecular weight. In particular, the UHMWPE reaches superior levels of resistance against cut and wear, whilst keeping flexibility and mobility. It is used for COFRA new generation anti-cut models, which take advantage of its ductility and toughness.
 FIBERGUARD-tr-ico  

Composite yarn engineered by COFRA by joining the features of the most resistant materials on the market, among which UHMWPE and steel (completely devoid of fi breglass). The result is a highperforming and thin yarn, able to reach level “5” in terms of resistance to cut, even in case of gloves with light polyurethane coatings.

 NEXTOFIL-ico2  

Latest generation material developed by COFRA, fiberglass-free. Guarantees good flexibility and high mechanical performance. Its thin diameter lends itself very well to weaving with other yarns giving highly resistant linings, without compromising flexibility and softness.

 NYLIRON-ico2  

Nylon flexibility is joined with the resistance of steel. The union of these two materials has allowed to obtain a wire with exceptional performance which ensures flexibility and lightness, allowing at the same time a better cut protection than the normal nylon, improving glove durability.

 3M-THINSULATE-tr-ico  

Microfibre padding characterized by a complexive surface 10 times larger than the usual fibres. This implies that the THINSULATE™ microfibres keep more air, thus reducing the passage of warmth from inside to outside. This guarantees a constant thermal insulation even with strong wind and low temperatures. THINSULATE™ is a trademark of 3M.

[/vc_column_text][/vc_column][vc_column width=”1/2″][vc_column_text]

THE LEATHERS

[/vc_column_text][vc_column_text]

During manufacturing and stratification, the leather is split into two parts: the external layer is called full grain leather and it is the one used to provide further softness and comfort, the internal layer is called split leather to provide better mechanical performance such as resistance to tear and wear.

COW LEATHER

Highly resistant to abrasion and to atmospheric agents such as humidity and sunlight. Usually the cow leather gloves are thicker, thus providing greater resistance. On the market it is possible to find several kinds of gloves: COFRA carefully chooses leathers guaranteeing at the same time softness and resistance.

GOAT LEATHER

Unlike cow leather, goat leather is used with thinner thickness, thus enhancing feeling in fingers and dexterity. The lower thickness does not imply low mechanical resistance, and at the same time it allows better breathability.

CALF LEATHER

Calf is a very refined leather belonging to the cow leathers category, joining the advantages of a high mechanical resistance and low thickness that the cow leather is not able to provide. Very similar to goat leather but softer and more resistant.

AZO FREE   All the fabrics used for leather gloves are without AZO DYES.
