What is the difference between Class II and Class B?
Nothing. It's a matter of preference whether a building code designates alpha or numeric classification.
What do the fire-rated test result numbers mean?
The test numbers mean that the material has been ranked for Flame Spread and for Smoke Developed when compared to kiln-dried Red Oak at 100 and incombustible cement board at zero. For example, a Flame Spread of 25 means that the tested product would exhibit one-quarter the Flame Spread of Red Oak in the same situation.
What does fire-rated mean?
Fire-rated means that a product has been evaluated to determine relative Flame Spread and Smoke Developed indices. Based on these indices, a rating is developed for the product. Fire-rated laminates typically have a special composition in order to have low Flame Spread and Smoke Developed properties when burned.
Are special techniques in fabrication required when working with High Wear Laminate?
Yes, because more tool wear must be expected. High Wear Laminate is very abrasive, which causes it to be abrasion-resistant, and also causes it to attack tools.
Is High Wear Laminate surfacing suitable for use in chemical laboratories?
Only where chemicals are not in use. It will not resist chemicals any better than our normal laminate.
Does High Wear Laminate have more impact resistance than standard laminate?
No. It does not. Impact resistance is a function of the thickness of the laminate and also of the core to which it is bonded.
How much more durable is High Wear Laminate than our standard laminate?
A standard laminate tolerates about 500 cycles of abrasion wear in testing, while High Wear Laminate tolerates around 3,200 cycles. So it is five to six times more resistant to abrasion/wear.
Is Wilsonart High Wear Laminate surfacing available in all standard Wilsonart Laminate sizes?
Yes. Please note that High Wear is a factory order product type; allow two weeks additional lead time for all orders.
Can High Wear Laminate surfacing be manufactured in all standard thicknesses?
Yes. However, High Wear Laminate cannot have a gloss finish; it must have a textured finish.
Is Wilsonart High Wear Laminate available in all Wilsonart solid colors, designs and woodgrains?
Please note that the High Wear overlay quite often makes certain designs (especially solid colors) appear somewhat different. Colors may not match exactly with conventional laminate and may be cloudy in appearance. Woodgrains are generally not affected by the overlay. (Woodgrains mask the change better.) We recommend ordering samples of any laminate with the High Wear overlay before placing an order.

Is your manufacturing process different from those of other manufacturers?
To some extent, it is; we all use presses, we all use cure cycles and so forth; the papers and resins are very similar. But the way we cure resins and handle them in certain respects is different, and we do consider these techniques proprietary.
Do all Wilsonart laminate products postform? Why do some colors postform more easily than others do?
No, only the 300 series of products are manufactured to postform with the aid of heat. The laminates finish, color, and/or pattern will affect the heat transfer rate throughout the laminates thickness. As an example, white laminates will reflect heat and therefore will require more heat to transfer 325Â°F in 25 + 5 seconds throughout the laminate thickness. Dark laminates will absorb heat and therefore will require less heat to transfer 325Â°F in 25 + 5 seconds throughout the laminate thickness.
What is the blister point of postforming grade laminate?
Blister points for postforming and general purpose grade laminate is in the range of 400 degrees Fahrenheit. The time at any given temperature is a big factor. Postforming grade laminates should never blister in less than 40 seconds if temperature is quickly increased to 325 degrees Fahrenheit in 25 + 5 seconds. This margin assures good forming and good blister resistance. As an example, a hot pot containing oil heated to 356 degrees Fahrenheit will not blister laminate as it cools, but if this temperature is maintained, damage may result.
What are the radii to which Wilsonart Laminate can be formed? What is the ideal forming temperature?
ANSI/NEMA LD3-2000 performance standards for formability are 5/8? (16mm) outside radii for horizontal grade postform (HGP) and Â½? (13mm) outside radii for vertical grade postform (VGP). Typical results for Wilsonart postforming grade 350 (HGP) laminate is 9/16" (14.3mm) outside and 3/16" (4.8mm) inside radii. Typical results for Wilsonart vertical grade 335 (VGP) laminate is 7/16" (11.1mm) outside and 3/16" (4.8mm) inside radii. Smaller radii may be achieved depending on the postforming equipment and the degree of craftsmanship. The ideal forming temperature for Wilsonart postformable laminate grades 350 (HGP) and 335 (VGP) is 325Â°F in 20 + 5 seconds throughout its thickness. The laminates finish, color, and/or pattern will affect the heat transfer rate throughout the laminates thickness.
Cold forming of Wilsonart Laminate depends on the thickness of the product. For example, Product 335 (VGP) can be bent to a 7" (177.8mm) radius; Product 350 (HGS) to a 9" (228.6mm) radius; and Product 107 (HGS) to a 12" (304.8mm) radius (all cold bends).
Why is postforming grade material priced higher than general purpose grade?
Postforming grade laminate costs more to produce because it requires premium papers and resin treatments. Quality control must be tighter to assure a well-manufactured product that will perform properly.
What is the difference between vertical grade type 335, postforming grade 350 and general purpose grade 107?
First, thickness: vertical grade 335 (VGP) is .028" + .004" (.7mm + .1mm), postforming grade 350 (HGP) is .039" + .005" (1.0mm + .12mm), and general purpose grade 107 (HGS) is .048" + .005" (1.2mm + .12mm).
Also, vertical and postforming grades can be postformed to a simple radius, while general purpose grade is intended for flat work only. The thickness of our products does not affect wear characteristics.
What are the "basic types" of Wilsonart Laminate?
All high-pressure decorative laminate (HPDL) is available in three basic types or grades:
- General Purpose Type 107 (HGS) is produced for both horizontal and vertical interior applications where the surface must be functional, decorative and durable.Â
- Vertical Surface Type 335 (VGP) is intended for vertical interior applications where the surface will absorb somewhat less impact than a comparable horizontal surface. This type may be postformed to achieve radiused edges.
- Postforming Type 350 (HGP) is intended for use on vertical or horizontal interior surfaces where it is necessary or desirable to roll the laminate on a simple radius over the edge of the substrate. This eliminates seams and creates an attractive surface.
What organization establishes the performance standards for high-pressure decorative laminate (HPDL)?
The performance standards are established by American National Standards Institute/National Electrical Manufacturers Association (ANSI/NEMA) LD3-2000 for high-pressure laminate. Wilsonart Laminates meet or exceed the performance standards set by ANSI/NEMA LD3-2000 for high-pressure laminate.
