|Thermoforming draws heated Boltaron sheet onto molds using vacuum from below and (typically) pressure from above the sheet, creating a self-supporting 3-D part that, following secondary operations, can be fastened to the kiosk structure to house displays, lighting, keypads, etc. The extreme impact resistance of Boltaron sheet protects the structure and it's internal components from the abuse typical of kiosk applications, while facilitating current 3-D design forms and improving visual appeal, owing to the unlimited solid colors, scratch-resistant metallics and numerous textures available.
A rapidly growing method of creating field-replaceable kiosk panels is by membrane pressing (also called 3-D laminating) in which MDF (medium density fiberboard) substrates are routed into three-dimensional shapes, and then membrane pressed (vacuum laminated) using damage resistant Boltaron sheet. The sheet encapsulates all top and side surfaces routed into the substrate, including compound curves, detailed profiles and deep recesses even openings routed completely through the substrate for wiring and rear-mounted displays and keypads with seamless, durable Boltaron sheet. The component is then trimmed of excess at its bottom edge and fastened to the kiosk's internal frame, allowing rapid, inexpensive field replacement in the event of extreme damage.
No other thermoplastic sheet surpasses Boltaron PVC/Acrylic alloy for membrane pressing and thermoforming of kiosk panels for practical and aesthetic reasons:
|Wide range of PVC/Acrylic alloys with UL Std 94 V-0, UL Std 94 5V, ASTM E-84 and ASTM E-62 fire ratings. Also available non-fire-rated.
||Satisfies a wide range of performance and cost requirements while with meeting or exceeding fire standards if required.
|Extruded grades in gauges down to 0.18 in. (0.46 mm)
||Extruded gauges down to 0.18 in. (0.46 mm) satisfy a wide range of forming and fabrication requirements, while offering greater economy than competitive sheets offered in 0.022 in (0.56 mm) minimum thicknesses.In addition, the availability of matching heavy gauges up to 3.0 in. (76.2 mm) allow machining of thick parts identical in color, texture and properties to membrane pressable gauges of the same Boltaron grade.
|Metallics with integral color, providing unmatched brilliance and scratch resistance
||Unlike competitive metallics that are reverse-printed with metallic ink on clear cap film laminated to dissimilar substrate material, Boltaron metallics are comprised of a cap film with integral metallic coloration, permanently fused to a matching "9815-grade" substrate of a complementary solid color, preventing de-lamination and offering unsurpassed scratch resistance. Since the 9815M monolithic cap film is a "metallized" version of Boltaron's 9815 solid color substrate, metallic color selection is unlimited.
|Unlimited colors (including solids, translucents and metallics) with low minimums
||Unlimited custom colors with low minimums, no premiums and fast turnaround eliminates compromises associated with limited selections of standard colors, increasing customer satisfaction. Lot-to-lot color consistency allows undetectable field replacements.
|16 Standard surface textures, and custom textures with low minimums
||An exceptionally large number of standard textures, and virtually unheard of custom texture availability with low minimums, enable thermoformers and fabricators to satisfy the requirements of the most demanding specifiers, and in many cases to upgrade the part specification.
|Impact resistance to 20 ft-lbs/in (1059 J/m)
||Compare the impact resistance of Boltaron sheet with that of any competitive sheet and you may specify Boltaron on the basis of impact alone. With impact ratings to 20 ft-lbs/in (1059 J/m), Boltaron enables kiosks to withstand the abuse associated with high traffic environments while maintaining a like-new appearance.
|Readily thermoformed and membrane pressed (3-D laminated)
||Among the greatest benefits of Boltaron sheet to kiosk manufacturers is its ability to conform to 3-D shapes created by thermoforming or membrane pressing while maintaining uniform wall thickness.
|Extreme chemical resistance
||Boltaron's PVC and PVC/Acrylic alloys are among the most chemical resistant of all plastics, allowing grime and graffiti to be removed repeatedly from kiosks using concentrated chemicals, with no adverse effects.
Boltaron offers the following specialized grades of PVC/alloys for membrane pressing of damage-resistant kiosk panels:
|Most popular grade|
- Boltaron 4335
Boltaron 4335 is a proprietary, fire retardant, extruded Acrylic/PVC Alloy sheet. Boltaron 4335 offers a UL 94 V-0 rating, excellent impact strength, abrasion resistance, chemical resistance, rigidity and thermoformability. Boltaron 4335 is cost competitive with FR ABS but offers superior performance.
- Boltaron 1165
Boltaron® 1165 sheet, extruded from select aircraft and electrical grade recycled trim and resin, provides an exceptional combination of UL 94 V-0 compliance, physical
properties, consistent thermoforming and low cost compared with other flame rated sheet products.
- Boltaron 4065MP
Boltaron 4065MP is a proprietary, PVC/Acrylic alloy sheet designed for use in membrane pressing (3-D laminating) and flat laminating applications. It combines excellent impact strength, abrasion resistance, rigidity, durability, chemical resistance and fire retardancy, and affords designers the flexibility to incorporate unlimited three dimensional shapes while eliminating the slab-sided shapes, unsightly seams, edge banding and de-lamination associated with high pressure laminates. In addition, it is available in a wider range of thicknesses down to 18 mil (compared with competitive PVC/Acrylic alloys of 22 mil minimum thickness) enabling you to compete price-wise with thermofoil films while providing superior resistance to damage. Boltaron 4065MP carries a UL 94 V-0 fire rating.
- Boltaron 4330M (Metallic)
Boltaron 4330M is a proprietary, dual layer, metallic thermoplastic sheet. Boltaron 4330 offers a UL 94 V-0 rating and meets stringent FAA flammability requirements. Boltaron 4330M combines excellent impact strength, abrasion resistance, rigidity, and chemical resistance with superior thermoformability.
