| Nitrile (synthetic rubber) | Latex-free; commonly selected for examination use and resistance to many oils and chemicals. Compatibility varies by chemical, concentration, temperature, and contact time. | Check the supplier’s size chart for XS–XL availability, palm width, finger length, and cuff length. Size labels alone do not guarantee identical fit. | Request tensile-strength and elongation results for the exact model, including conditioning/aging status and test method. ASTM D6319 is a relevant specification for nitrile examination gloves. | For chemical protection, request substance-specific permeation data; a tensile result does not establish chemical breakthrough time. |
| Natural rubber latex | Elastic material with a close fit and good tactile sensitivity. Natural rubber latex proteins can cause allergic reactions in sensitized users. | Confirm measured dimensions by size and whether the offered range matches the intended user population. | Request model-specific tensile-strength and elongation results, with test method and aging details. ASTM D3578 covers rubber examination gloves. | Confirm labeling and allergen-related information, plus the intended-use and regulatory documentation for the destination market. |
| Polyvinyl chloride (PVC / vinyl) | Latex-free option commonly used for lower-risk, short-duration tasks. Fit, dexterity, and chemical suitability differ from elastomeric gloves. | Request actual palm-width and length measurements for each offered size; compare fit rather than relying only on S/M/L labels. | Request product-specific tensile and elongation test results and the cited specification. ASTM D5250 covers PVC examination gloves. | Do not infer suitability for hazardous chemicals from material name alone; ask for test data for the exact chemical and use conditions. |
| All material types | Performance depends on glove design, thickness, manufacturing, and intended use; compare like-for-like models. | Ask for size-specific dimensions and manufacturing tolerances, where available. | Compare results only when test methods, specimen preparation, and aging conditions are equivalent. Do not treat an unverified supplier claim as a standardized result. | Verify applicable market requirements and documentation, such as relevant FDA requirements in the United States or EN 455 requirements in the European context. Confirm the current requirements for the product and market. |
