Thin Butyl Protection for Chemical Transfer and Process Tasks
Ansell AlphaTec® 38-514, formerly ChemTek™ 38-514, is an unsupported butyl chemical-resistant glove with a 0.35 mm (13.8 mil, nominal 14 mil) palm thickness and a 350 mm (13.8-inch) length. Its soft, ergonomic shape supports dexterity, while the rough hand finish helps with handling control.
Ansell identifies the butyl formulation for work involving chemical families that include aldehydes, ketones, esters, and concentrated mineral acids. The exact chemical, concentration, temperature, exposure time, and published permeation data must be reviewed before the glove is selected for a task.

Safety Standards and Chemical Glove Selection
OSHA 29 CFR 1910.138 — Hand Protection requires appropriate hand protection where workers face hazards such as skin absorption of harmful substances or chemical burns. Selection must consider glove performance, the task, conditions, and duration of use.
OSHA 29 CFR 1910.132(d) — Hazard Assessment and PPE Selection requires employers to assess workplace hazards and select PPE that properly fits each affected employee. These are employer requirements, not an OSHA approval of this glove.
Ansell lists EN ISO 374-1:2016 Type A, ABCIKMPST for chemical protection; EN 388:2016 + A1:2018, 1000X for mechanical performance; and EN ISO 21420:2020 for general protective-glove requirements. Chemical test classifications do not establish a safe wear time for every substance or mixture. Use current manufacturer compatibility data for the actual exposure.
Ansell also reports testing to EN 16350, but states that inclusion in product certification is pending. Do not treat this as a completed EN 16350 certification or as electrical shock protection.

Ansell AlphaTec 38-514 Butyl Glove FAQ
Is AlphaTec 38-514 the same glove as ChemTek 38-514?
Yes. Ansell identifies AlphaTec 38-514 as the current name for the product previously sold as ChemTek 38-514.
Which chemicals are AlphaTec 38-514 gloves designed to resist?
Ansell lists aldehydes, ketones, esters, and concentrated mineral acids among the chemical families associated with the butyl formulation. This is not a universal compatibility claim. Check Ansell's current permeation and degradation data for the exact chemical, concentration, temperature, and exposure time before use.
How thick and how long are the gloves?
Ansell specifies a 0.35 mm (13.8 mil, nominal 14 mil) palm thickness and a 350 mm length, which is approximately 13.8 inches and commonly described as 14 inches.
Which standards are listed for AlphaTec 38-514?
Ansell lists EN ISO 374-1 Type A with code ABCIKMPST and EN 388:2016 + A1:2018 result 1000X. These results must be interpreted with the task hazard assessment and manufacturer instructions.
Which sizes does Ansell make for the U.S. market?
Ansell's U.S. product data lists numeric sizes 7, 8, 9, and 10. Use the size selector above the description for current ASA availability after confirming that its labels match the manufacturer sizes.
Are AlphaTec 38-514 gloves latex free?
Ansell describes the formulation as latex free. The manufacturer also discloses chemical vulcanization accelerators that may cause irritation or contact allergy in a small number of users.
How is this product sold?
ASA lists the product by the pair. Ansell's manufacturer carton contains 36 individually wrapped pairs, each packed with an information insert.
Are these gloves intended for cut protection?
Chemical protection is the primary purpose of AlphaTec 38-514. Its EN 388 result is 1000X, so it should not replace a glove selected for a required cut, puncture, impact, thermal, or electrical rating.
