Microflex SU-690 Supreno SE Accelerator-Free Nitrile Gloves, Large, 100 Count

Conventional nitrile gloves are manufactured using chemical accelerators (primarily thiurams, dithiocarbamates, and mercaptobenzothiazoles) that cure the nitrile polymer. These residual chemicals cause Type IV delayed hypersensitivity reactions in some users. Accelerator-free or accelerator-reduced gloves like the Supreno SE are produced using alternative curing processes that significantly reduce or eliminate these compounds.

Only if you experience Type IV contact dermatitis from standard nitrile — symptoms include redness, itching, blistering, or a rash appearing 6–72 hours after glove removal. If standard nitrile causes no reactions, the MedPride Exam Nitrile or Halyard Purple Nitrile provide better value.

No. "Latex-free" means no natural rubber latex — all nitrile gloves qualify. "Accelerator-free" addresses a different sensitivity: reactions to the chemical accelerators used in nitrile manufacturing, not to latex itself. You can have a Type IV nitrile accelerator reaction and no latex allergy simultaneously.

Type IV (delayed) hypersensitivity is a cell-mediated immune reaction to chemical accelerators in gloves, not to nitrile itself. Symptoms appear hours after exposure — redness, itching, dry skin, or blisters on the hands. It is distinct from Type I IgE-mediated latex allergy (immediate reaction). Accelerator-free gloves address Type IV reactions. Our Nitrile Glove Buyer's Guide covers glove allergy types in detail.

Yes. Powder-free formulation — appropriate for medical-adjacent environments where powder contamination is a concern.

Yes — healthcare workers with documented Type IV nitrile accelerator sensitivity are the primary intended users. These should be selected in consultation with occupational health when standard nitrile causes documented reactions.

Yes. The Supreno SE is used in pharmaceutical laboratories, research environments, and medical facilities where staff require accelerator-reduced protection. Verify specific chemical compatibility for your applications.

Accelerator-free gloves typically cost 2–4× more per glove than standard exam nitrile. This premium is only justified when there is a documented sensitivity. For value exam nitrile, the MedPride Exam Nitrile at ~$0.10/glove is the benchmark.

Yes — single-use disposable. For reusable nitrile options, see the PIP MaxiFlex G-Tek or Grease Monkey Nitrile Work Gloves.

Yes. Dental professionals are among the occupational groups with higher documented rates of nitrile accelerator sensitivity due to high-frequency glove use. Accelerator-free nitrile is the recommended specification for affected staff.

Vinyl gloves do not contain rubber accelerators and can be an option for low-risk tasks where users cannot tolerate nitrile. However, vinyl offers significantly less chemical and puncture protection. Browse our vinyl gloves collection or compare in our Nitrile Glove Buyer's Guide.
