Medcare developed a unique formula that is used to produce one type of gloves and combine two main purposes:  Examination gloves & Chemotherapy drugs resistant gloves.

Our mission was to produce gloves, which are comfortable for the end-user, offering high protection levels, are resistant to different chemicals/drugs and allergy-free, and suitable for many usages.

Working closely together with industry experts from engineering, research, and testing with end customers in the food and medical industries, Medcare successfully developed a formula that combines all the benefits of Nitrile gloves and durable Neoprene gloves to provide a perfect solution for our customers.

Materials

Nitrile rubber (composed of acrylonitrile and butadiene) as a material for disposable gloves is a high-quality material with rapidly increasing market significance. Although the material is less elastic than latex (and therefore less comfortable), its resistance to chemicals is higher than that of latex and its mechanical properties are very good. Latex proteins are not included, so there is no risk of latex allergy. Recently, however, some users of gloves have experienced another form of allergy, namely sensitization by vulcanization accelerators (e.g. by thiurams). This is not a problem of nitrile alone but also applies to latex. Vulcanization accelerators are used to increase the technical polymerization process to the level required by the industry.

Although vulcanization accelerators are only used in small amounts as auxiliary material in the polymerization process, often a small amount in the microgram range is sufficient to trigger an allergy. Gloves are therefore washed after production to remove the vulcanization accelerators. There are also already vulcanization accelerator-free further developments.

HDPE (High-Density Polyethylene) gloves are usually inelastic, crystal-clear, or colored, largely resistant to acids, alkalis, oils, and fats, and can therefore be used in the food industry with the appropriate approval. Such gloves are mostly used as product protection (food industry), e.g. to prevent the transmission of germs to food.

Latex is the oldest and most classic material for disposable gloves, made from a natural product (natural rubber). Latex gloves have conquered their place in the working world due to their elasticity and the wearing comfort they provide. They are used in both the medical and industrial sectors. In the industrial sector, their chemical resistance to many acids, bases, and alcohols is an advantage. In the food sector, however, their use of oils and fats is not possible. A major disadvantage of disposable gloves made of natural latex is their allergic potential due to the latex proteins they contain as allergenic triggers. This allergenic potential is multiplied many times over by powder (e.g. corn starch). The share of powdered gloves in the market is strongly declining, with the exception of some countries. Manufacturers try to suppress the transfer of latex proteins to the skin by coating the inside of the glove with a non-allergenic material.

Vinyl stands out for its price advantage. Its mechanical properties and comfort are below average, as is its resistance to chemicals. Vinyl is PVC and is processed together with suitable plasticizers. The plasticizers are usually phthalates and must be REACH-compliant. Although the phthalates used are REACH-compliant, there are restrictions. Vinyl gloves cannot be used with fat or fatty foods. However, they do have skin-friendliness benefits for users who suffer from latex or chemical allergies.

Polyisoprene is a synthetic rubber. A latex allergy is impossible with polyisoprene. Gloves made of this extremely elastic material are mainly used in the medical field as surgical gloves. They have a particularly cuddly fit and sensitivity.
