Thermoformable ABS Sheet – Engineered for Precision Vacuum Forming
When it comes to vacuum forming, thermoformable ABS sheet stands out as one of the most reliable and versatile materials in the plastics industry. Why? Because ABS offers an exceptional balance of melt strength, elongation, and thermal stability, allowing it to draw deeply into complex molds with uniform wall thickness, minimal sagging, and excellent surface reproduction. Unlike many other thermoplastics, thermoformable ABS sheet processes consistently across a wide temperature window, reducing scrap rates and cycle times-making it the go-to choice for manufacturers who demand repeatable, high-quality formed parts.
But not all thermoformable ABS sheet is the same. Depending on your end-use environment, we offer two specialized product families, each engineered to elevate performance while retaining the core forming advantages of ABS.
ASA ABS Sheet – UV-Stabilized for Outdoor Refrigeration Equipment
Outdoor refrigeration-think beverage coolers, ice makers, vending machines, and transport refrigeration units-faces relentless sun, rain, and temperature swings. Standard ABS can yellow, chalk, or lose impact strength under UV exposure. That's why our ASA ABS thermoformable sheet combines the forming ease of ABS with an acrylic-styrene-acrylonitrile (ASA) cap layer or alloy, delivering:
Superior UV resistance – Retains gloss and color integrity for >2,000 hours of QUV testing, ensuring your refrigeration cabinets stay brand-new-looking in sun-drenched locations.
Weatherability – Resists moisture absorption and thermal cycling, preventing warping or stress cracking in outdoor climates from –30°C to +70°C.
Same vacuum-forming performance – Our ASA ABS grade stretches and cools just like standard ABS, so you can use existing molds and process parameters without retooling.
Available textures – From fine grain to anti-graffiti matte finishes, ideal for high-touch commercial refrigeration doors and control panels.
This thermoformable ABS sheet variant is widely used for condenser housings, ice storage bins, and solar-shielded display cases, where long-term aesthetic and structural integrity are non-negotiable.
PC/ABS Sheet – High-Impact Toughness for EV Battery Packs
Electric vehicle battery systems demand flame-retardant, crash-resistant, and dimensionally stable enclosures-yet these large, deep-drawn covers and trays must still be vacuum-formable. Our PC/ABS thermoformable ABS sheet (polycarbonate/ABS blend) answers that challenge with:
Outstanding impact resistance – Retains ductility down to –40°C, passing instrumented dart impact tests at >50 J, making it suitable for under-vehicle battery underbody shields and top covers that must withstand stone strikes and vibration.
Enhanced heat deflection – Withstands peak operating temperatures up to 110°C (HDT @ 0.45 MPa), protecting sensitive cell modules during fast-charging sessions.
Flame retardancy – Available in UL94 V-0 or V-2 ratings without sacrificing the deep-draw forming characteristics of thermoformable ABS sheet.
Dimensional precision – Low creep and low coefficient of thermal expansion ensure tight sealing with gaskets and busbars, critical for IP67-rated battery housings.
Lightweighting – Compared to metal or SMC, this sheet cuts weight by 30–50%, directly extending EV range.
Automakers and tier-1 suppliers choose our PC/ABS thermoformable ABS sheet for cell-to-pack structural covers, module spacers, and cooling channel formings-all produced on standard vacuum-forming lines with minor oven tuning.
