GLN HDPE 1/4″ 8″ x 12″ Black Sheet
The GLN HDPE sheet provides a 0.25″ thickness with dimensions of 8″ x 12″ in black. It is constructed from high-density polyethylene that offers strong resistance to water, impact, chemicals, weather, and stains. Ideal uses include tapping blocks for floor installation, DIY parts, and parts produced via CNC machining, bending, or heat gun forming. The sheet’s durability and machinability make it suitable for hobbyist projects and professional builds alike.
CALPALMY 12 x 12 Clear Acrylic 1/4″ Sheet
These CALPALMY acrylic sheets are premium 1/4″ thick with exceptional clarity suitable for plexiglass windows and craft applications. They weigh less than glass while maintaining glass-like transparency. The sheets resist UV exposure and weather, performing well indoors or outdoors for up to several decades. They ship with a protective film, and the two-sided versatility makes them great for signs, displays, craft projects, and protective barriers or sneeze guards in light-duty setups.
DIYDIYSHOP HDPE 1/4″ White Sheet
This white HDPE sheet measures 1/4″ x 8″ x 12″ and is described as corrosion-resistant with good chemical resistance and durability under repeated use. White HDPE is favored for marine-grade projects and long-term applications where stability, low friction, and resistance to staining are important. It’s compatible with CNC machining, heat forming, and standard cutting tools, making it a versatile option for DIY boat builds, cutting boards, or signage substrates.
MOKOVI 12″ x 16″ ABS 1/4″ Sheet, Black
The MOKOVI ABS sheet measures 12″ x 16″ x 1/4″ with a black color. ABS sheets offer good impact resistance and thermoformability, allowing bending to angles when heated to around 93°C (200°F). They can be easily cut with common tools and are suited for signage, interior displays, dashboard panels, decorative panels, and other DIY crafts. The dual-sided texture and formability support a variety of sign-making and display applications.
GLN 12″ x 16″ HDPE 1/4″ Black Sheet
The GLN HDPE sheet in 12″ x 16″ dimensions provides a durable 1/4″ thick block designed for tapping blocks, precision part fabrication, and DIY projects. Its high-density polyethylene composition delivers excellent resistance to water, chemicals, and weathering, making it well-suited for workshop benches, machine shop jigs, and lightweight structural components that require a stable, cut-friendly substrate.
Buying Guide: Key Considerations For 1/4″ Sheet Materials
- Material properties: HDPE offers impact resistance, chemical resistance, and low moisture absorption; ABS provides strong impact resistance and good thermoformability; acrylic (plexiglass) offers high clarity and UV resistance. Choose based on environmental exposure, mechanical loads, and clarity requirements.
- Dimensional stability: Check tolerance and potential warping during machining or thermal forming. A ±1/8 inch cut tolerance is common for acrylic sheets; verify tolerances listed by the seller for each product.
- Machinability: For CNC, laser, or saw cutting, confirm suitability. HDPE and ABS are generally easy to machine; acrylic can be cut cleanly with the right blade and slow feed.
- Weight vs. strength: Acrylic provides glass-like clarity with higher weight; HDPE is lighter and more impact resistant in certain conditions; ABS offers good stiffness and formability. Choose based on whether weight or rigidity is a priority.
- UV and weather exposure: Acrylic and certain HDPE grades offer UV resistance for outdoor use; for long outdoor exposure, verify UV stabilization.
- Applications match: Tapping blocks, floor installations, and CNC parts are common for HDPE; signs and displays fit ABS and acrylic; craft projects align with acrylic and clear plastics.
- Finish and aesthetics: If visibility and display quality matter, prioritize acrylic or clear acrylic films; for rugged uses, HDPE provides durability without excessive weight.
- Cost and availability: HDPE and ABS typically offer cost-effective, durable options; acrylic may be pricier but provides superior clarity. Compare sheet sizes to minimize waste and optimize procurement.
