Automotive Protective Equipment and Safety Frequently Asked Questions

1. How is cut resistance measured?

Answer: A Cut Protection Performance Test (CPPT) is the approved test procedure/machine approved by the ASTM committee. This test uses a load-versus-distance evaluation to determine the cut-through point of a material. A cutting blade (surgical-grade razor) with a specified load (weight) is moved across a material. The distance at which the blade traveled from the original contact point to the cut-through point is measured for several loads (weights). After several tests, a load-versus-distance curve is plotted and this is used to determine the load required to cut through the material at 25MM (reference load).

2. Are there special laundering instructions for knitted gloves made of, or containing, DuPont™ Kevlar®?

Answer: Knitted gloves containing Kevlar® or Kevlar® blends can be either water-washed or dry cleaned. If water washing is utilized, no chlorine bleach should be used.

3. Where can I purchase your products?

Answer: Through an authorized Ansell distributor in your area or an integrated supplier that holds the current contract for your facility.

4. What's my lead-time on orders & samples?

Answer: Standard products: 2 to 3 days. Custom products: 4 to 6 weeks.

5. How many times can knitted gloves made of, or containing, Kevlar® be laundered?

Answer: This varies greatly from application to application and depends a lot on how well the industrial detergent cleans the product. On average, Kevlar® can be laundered anywhere from two to five times.

6. Can I get any of these products in a non-standard color or design?

Answer: Yes, customization is available. Find out more.

7. How is The Eliminator™ cleaned before packaging?

Answer: This product is cleaned and packaged in a Class 10 cleanroom using the most modern, up-to-date cleanroom technology.

8. What is the level of heat resistance protection that Kevlar® provides? How about Kevlar® cut resistance versus cotton?

Answer: Knitted Kevlar® can vary in heat resistance based on the yarn thickness. Heavyweight Kevlar® styles can withstand 200° F for short intervals but the level of heat resistance can go as high as 400° F). Heat transfer through Kevlar® is slower than that of cotton or leather, however the dissipating factor is also slower. This slow dissipation rate is critical if the end-user is handling hot objects (over 200° F) for long periods of time without any breaks between handling parts.

Cotton is still used in many mid- range temperature (300° F to 400° F) applications because it dissipates heat much better and is a natural fiber that actually "breathes" better than man-made fibers like Kevlar®.

9. How much more cut resistances does Kevlar® offer over leather?

Answer: CPPT data shows that Kevlar® is up to five times more cut resistant than leather.

10. Which product offers better heat resistance, Kevlar® or cotton?

Answer: Cotton actually offers as good or better heat resistance, but Kevlar® offers better flame resistance.

11. On products using Kevlar®, why do you use different colors on the overedge of the cuffs?

Answer: This color-coding system enables you to easily identify the size of the product: Size (7 ) blue, (8) green, (9) red, (10) black.

12. What is the difference between Kevlar® and Twaron?

Both fibers are in the aramid family. According to testing performed by DuPont, the CPPT results for standard Kevlar® and Kevlar® Plus are 14% and 34% higher than Twaron, respectively.

*This information is based on the results of the accepted industry standard test for cut resistance, ASTM 1790-97, performed under laboratory conditions. The data are subject to revision as additional knowledge or experience is gained.

13. What is considered a moderate level of cut protection on a CPPT rating?

Answer: 800 to 1000.

14. Is there one universal glove that we can use in all our applications throughout the plant?

Answer: That depends on how many critical factors are involved in each application. There are a number of critical factors such as chemicals, cuts, abrasion, and heat that might require a different glove along with a different degree of protection.
