Newer generations of nitrile gloves are overcoming some of the disadvantages seen in earlier versions. Nitrile gloves are currently available in the same thicknesses as natural rubber latex and PVC. Nitrile is more durable than both vinyl and latex, but it’s an inelastic polymer, which is more difficult to form into a thin, disposable glove. Some manufacturers take vinyl to contract manufacturers for additional cleaning and packaging. Vinyl is primarily sold in an ambidextrous smooth finish, and is best suited for a dry environment. Also, fingernails may puncture vinyl gloves. The biggest drawbacks of vinyl gloves include: loose fit, low durability, poor acid/base resistance, and touch transfer. Vinyl is also well suited for double gloving or wearing glove liners. Vinyl has several advantages: It is inert and does not shed many particles no powder is used in making vinyl gloves it’s non-allergenic and has some antistatic properties and vinyl is usually a few cents cheaper than latex. They are not as durable or as good a barrier as latex, however, and because vinyl may outgas, it should be tested for such. Vinyl (PVC) gloves, invented by Oak Technical LLC in the late 1950s, are in second place. As it ages, it continues to decay and flake. Latex falls short in static dissipation, and also sheds its outer layer as it becomes worn. However, concerns about allergic reactions and a reduction in the cost differential have allowed nitrile to capture a significant share of the market. Latex comes in hand-specific, ambidextrous, textured and smooth versions. They are the most elastic and durable, have good acid resistance and come in various thicknesses and lengths. Natural rubber latex gloves have been the first choice for cleanroom gloves. Due to the fact that the gloves are frequently in contact with the product, the cleanliness and protective aspects are also critical. This can be affected by material selection, sizing, thickness and length. Because gloves are in constant contact with the user, comfort and tactile sense are of high importance. It is the largest and one of the most critical purchases for cleanroom operators. By Robert McIlvaine and Betty Tessien, McIlvaine CompanyĬleanroom operators around the world will spend close to $1 billion for gloves this year.
