3mm vs 4mm Solid Polycarbonate Sheet
| Thickness |
Selection Consideration |
| 3mm |
Lower sheet weight and greater flexibility for suitable glazing, covers, partitions and fabricated panels. |
| 4mm |
Greater thickness and rigidity where additional panel stiffness is required. |
Final thickness selection should consider panel dimensions, support spacing, wind load, impact requirements, bending radius and installation method.
UV-Coated Polycarbonate Sheet for Outdoor Use
The existing product information states that an ultraviolet coextruded layer is used on the sheet surface to improve resistance to UV-related aging and yellowing.
For exterior projects, buyers should confirm whether UV protection is required on one side or both sides and which protected surface must face the exterior.
UV protection, abrasion resistance, solar heat control and flame-retardant performance are separate functions and should be specified independently where required.
4×8 ft Transparent Polycarbonate Sheet
The product name identifies this material as a 4×8 ft transparent solid polycarbonate sheet. Current product attributes list 1220 × 2400mm and 1200 × 2150mm together with custom-size availability.
Another existing product specification on this page lists 1220 × 2440mm as the standard size. Buyers should provide the exact required finished dimensions when requesting a quotation.

Existing Polycarbonate Material Features
High Light Transmission: The original product content states light transmission up to 88% compared with general glass of the same thickness. Actual transmission should be confirmed for the exact 3mm or 4mm sheet and color.
Impact Resistance: The original content states impact resistance of 80 times that of glass. Buyers requiring a defined engineering value should request the applicable test method and technical data.
Weather and UV Resistance: The existing source states that an ultraviolet coextruded layer helps reduce resin fatigue or yellowing caused by UV exposure.
Temperature Range: The original source lists 40°C ~ +120°C. Because the source does not contain a minus sign before 40°C, the lower limit should be confirmed before use as an engineering specification.
Light Weight: The source states that the material is only 1/12 the weight of glass of the same thickness. Projects requiring an exact sheet weight should confirm the supplied grade and thickness.
Formability: Existing content states that the material can be cold bent and thermally shaped.
Flame Resistance: Class B1 is listed in the original content. Buyers requiring formal fire compliance should confirm the corresponding test standard and report for the exact sheet grade and thickness.
Sound and Heat Insulation: These characteristics are mentioned in the existing content. Projects with defined acoustic or thermal requirements should request corresponding test values.
Transparent Solid Polycarbonate Sheet Applications
Glazing and Transparent Panels: Suitable PC grades can be considered for transparent glazing, partitions and supported panels where visibility and impact resistance are required.
Canopies and Construction: UV-protected solid polycarbonate can be considered for suitable exterior canopies and construction panels, subject to project structural and installation requirements.
Protective Panels and Equipment Covers: Polycarbonate is commonly selected where transparent protection and fabrication capability are required.
Electronic Appliances: The original product content lists insulating plug-ins, coil frames, tube sockets and battery shells among general PC applications.
Mechanical Equipment: The original content lists gears, racks, bolts, levers, housings, covers and frames among general polycarbonate applications.
Medical Equipment: Medical applications are mentioned in the original source. Actual medical use requires an appropriate material grade and application-specific regulatory documentation.

Frequently Asked Questions About 3mm 4mm Polycarbonate Sheet
Is this product available in both 3mm and 4mm?
Yes. The current product name specifically identifies 3mm and 4mm as the featured thicknesses.
What sheet sizes are listed?
Current product attributes list 1220 × 2400mm, 1200 × 2150mm and custom sizes. Another existing specification on this page lists 1220 × 2440mm.
Is this polycarbonate sheet UV coated?
The product name identifies the sheet as UV coated, and the existing content describes an ultraviolet coextruded layer on the sheet surface.
Is the UV protection on one side or both sides?
The current source does not specify whether the exact 3mm or 4mm grade has UV protection on one side or both sides. Confirm the required configuration before ordering.
What colors are available?
Current product attributes list clear, clear with color and opaque color. Another existing product specification lists clear, blue, green, opal, brown and grey.
What is the light transmission?
The existing page states light transmission up to 88%. Actual transmission should be confirmed for the exact 3mm or 4mm sheet, color and UV configuration.
How impact resistant is the sheet?
Existing content states impact resistance of 80 times that of glass. Projects requiring a defined impact performance should request the applicable test method and technical data for the exact sheet.
Can 3mm or 4mm polycarbonate sheet be cold bent?
The existing product information states that polycarbonate can be cold bent. The allowable radius depends on thickness, grade and finished-panel geometry.
Can the sheet be thermoformed?
Yes. Thermoforming is listed in the existing HSQY processing information. Provide the mold geometry and finished-part requirements when requesting formed components.
What fire rating is currently listed?
The existing product content lists Class B1. Formal fire requirements should be confirmed against the applicable test standard and report for the exact grade and thickness.
Can the sheet be cut to a custom size?
Current product attributes list custom size, and the existing company information lists precision cutting capability.
Can this sheet be used outdoors?
