|Cotton/Fabric Blend||Absorbs perspiration, keeps objects clean||No chemical resistance||Non-hazardous materials, slippery surfaces, mild heat or cold|
|Natural Rubber Latex||Low cost, good physical properties, dexterity||Poor vs. oils, greases, organics. Frequently imported; may be poor quality. May result in allergic reaction.||Bases, alcohols, dilute water solutions; fair vs. aldehydes, ketones, light irritant protection, infectious agents|
|Polyvinyl Chloride (PVC)||Very good physical properties, medium cost, medium chemical resistance||Plasticizers can be stripped; frequently imported, may be poor quality||Strong acids, and bases, salts, other water solutions, alcohols, oils, greases and petroleum products|
|Neoprene||Medium cost, medium chemical resistance, medium physical properties, high tensile strength and heat resistance||None determined||Oxidizing acids, anilines, phenol, glycol ethers, solvent oils, mild corrosives|
|Nitrile||Low cost, excellent physical properties, dexterity||Poor vs. benzene, methylene chloride, trichloroethylene, many ketones||Oils, greases, aliphatic chemicals, xylene, perchloroethylene; fair vs. toluene|
|Butyl||Speciality glove, polar organics, high resistance to gas and water vapor||Expensive, poor vs. hydrocarbons, chlorinated solvents||Glycol ethers, ketones, esters|
|Polyvinyl Alcohol (PVA)||Speciality glove, resists a very broad range of organics, good physical properties||Very expensive, water sensitive, poor vs. light alcohols||Aliphatics, aromatics, chlorinated solvents, ketones (except acetone), esters, ethers|
|Fluoroelastomer (Viton®)||Speciality glove, organic chlorinated and aromatic solvents. Flexible.||Extremely expensive, poor physical properties, poor vs. some ketones, esters, and amines||Aromatics, chlorinated solvents, also aliphatics and alcohols|
|Norfoil, Silver Shield®, 4H®||Excellent chemical resistance||Poor fit, stiff, easily punctured, poor grip||Use for Hazmat work|

|Leather||Good skin abrasion protection. Good grip||Absorb chemical contaminants||Injuries from sparks or scraping against rough surfaces. Used in combination with an insulated liner when working with electricity|
|Metal Mesh||Speciality glove. Protects against cuts when working with sharp tools||Expensive. Some models may reduce ability to grip||Protect hands from accidental cuts and scratches. Special micro-mesh versions available for use in high hazard procedures|
|Aluminized||Speciality glove. Heat resistant||Poor grip, discomfort. Poor chemical resistance||Insulates hands from intense heat working with molten materials|
Breakthrough Time: The elapsed time between initial contact of the chemical on the glove surface and the analytical detection on the inside of the glove. Typically expressed as a greater than symbol (>), this shows the test ran for 480 minutes and then stopped. Also may be expressed as "ND" for "None Detected".
Degradation: A change in one or more of the physical properties of a glove due to contact with a chemical. Can appear as a swelling, shrinkage or cracking of the material. Rating example is "E" for excellent, meaning the glove has little or no signs of degradation when exposed to the challenge chemical. A good degradation rating does not guarantee an acceptable breakthrough time.
Permeation Rate: The rate at which a chemical passes through a glove material. The process involves absorption on the glove surface, diffusion of the chemical through the material, and desorption on the inside surface of the glove. This is a complex measurement µg/cm2/MIN (micrograms per square centimeter per minute). This measurement is also limited to the "LDL" or Lower Detection Limit of the equipment used. The example give is .001, but is sometimes expressed as "E" or "P" for excellent or poor.
