Tensile strength is measured in the amount of force in pounds per square inch (psi or MPa) required to pull apart a product until material failure. If the tensile strength is too low, the glove will be weaker and more prone to tearing. However, excessive tensile strength does not necessarily mean the glove will ‘break’ when stretched; rather, it may become too stiff, affecting comfort and flexibility. A proper balance is essential to ensure durability while maintaining ease of donning and doffing.
Elongation refers to the glove’s ability to stretch under tensile force before reaching its breaking point. If elongation is too low, the glove may tear easily when snagged. On the other hand, high elongation does not directly compromise chemical protection, as permeation resistance is primarily determined by material composition and thickness. However, if the elongation rate is excessively high, the glove may become too loose, potentially affecting its fit and seal, which could indirectly impact protective performance.
A glove’s elongation and tensile strength are measured through laboratory testing, with industry standards set by ASTM. According to ASTM D6319, the minimum tensile strength for nitrile exam gloves before aging is 14 MPa, and the minimum elongation requirement is 500% before aging and 400% after aging. These strict standards ensure that gloves maintain their structural integrity and performance under various working conditions.
Our nitrile gloves exceed the minimum requirements by a significant margin, offering enhanced durability and reliability. Our products consistently meet or surpass industry expectations, ensuring superior protection and performance. These values may vary by product series, and the specifications for each glove can be found under the product description tab, providing transparency and clarity for users looking to make informed decisions.
Additionally, we closely monitor the modulus, which measures stiffness at low elongation values. This is another crucial factor in ensuring a balance between durability, comfort, and performance. A glove that is too stiff may reduce hand mobility, while one that is too flexible may not provide adequate support. Our research and development team continuously optimizes this balance to provide high-quality gloves that offer both exceptional protection and user comfort, catering to a wide range of industries and applications.
