Material |
Natural rubber latex from the rubber tree, Hevea brasilienis. |
Acrylonitrile butadiene, a synthetic
co-polymer. |
Polyvinyl chloride, a synthetic
co-polymer. |
|
Barrier Protection |
Strength, elasticity and chemical resistance make latex a reliable and effective barrier. |
Nitrile exhibits strength, elasticity and resistance to a wider range of chemicals than vinyl or latex, offering excellent barrier protection. |
Vinyl provides moderate barrier protection given its limited strength and poor chemical resistance. Barrier effectiveness is compromised with use. |
|
Strength |
Superior, with a minimum tensile strength requirement of 14 MPa per ASTM standard. |
Excellent strength and puncture resistance. Minimum proposed ASTM tensile strength is 12.5 MPa. |
Limited, with the lowest minimal ASTM tensile strength of 9 MPa. |
|
Elasticity |
High levels of elasticity, memory and elongation (700% minimum ASTM standard) provide excellent fit. |
Medium to High, conforming to the user’s hand with use. Minimum ASTM requirement for elongation is 500%. |
Low to Medium, with moderate flexibility. Lower elongation properties (300% ASTM minimum) result in a loose-fitting glove. |
|
Durability |
Highly resistant to tears and punctures, with in-use failure rates reported in several studies ranging from 0% to 9%. |
Highly resistant to punctures and tears. Once punctured, tear is visible and easily propagated. Reported in-use failure rates range from 1% to 3%. |
Durability declines with use, resulting in medium to high in-use failure rates, ranging from 22% to 63% in rigorous or long-term procedures. |

Recommended Use |
Optimal choice based on overall performance. Material strength supports use in high-risk situations and potential exposure to blood borne pathogens. |
Latex properties make this an ideal synthetic alternative for latex-sensitized individuals. Premier choice for use in high-risk situations, including infectious agents and most chemicals. |
Low risk situations where exposure to blood borne pathogens is limited and for short-term, minimal stress situations. |
