Polycarbonate Sheet in Malaysia: Types, Properties, and Uses (2026)

A polycarbonate sheet is a strong, lightweight, transparent panel made from polycarbonate, an engineering thermoplastic prized for its exceptional impact resistance and clarity. In Malaysia it is widely used for roofing, skylights, awnings, and glazing because it combines near-glass transparency with the toughness to survive heavy tropical rain, sun, and impact.

This guide explains what a polycarbonate sheet is, the types available in Malaysia, their key properties, typical prices, and how to choose the right sheet for your project.

What a Polycarbonate Sheet Is

Polycarbonate is a high-performance engineering plastic, and the sheet form is produced by extruding that resin into flat or profiled panels. Its defining quality is impact strength: polycarbonate offers roughly 250 times the impact resistance of glass and around 30 times that of acrylic, which is why it is often described as virtually unbreakable. These material characteristics are formally classified under the standard for polycarbonate unfilled and reinforced material, ASTM D3935, which grades resins by properties such as Izod impact strength, tensile strength, and deflection temperature.

Beyond toughness, polycarbonate is highly transparent and about half the weight of glass, making sheets easier and safer to handle and install. For a fuller picture of the material's behaviour, an overview of polycarbonate as an engineering polymer sets out how its clarity, strength, and heat resistance combine in practical applications.

Types of Polycarbonate Sheet in Malaysia

Malaysian suppliers generally stock three main forms, each suited to different jobs. Solid polycarbonate sheet is a single dense layer that looks closest to glass, offering the highest clarity and strength for glazing, sound barriers, and security applications. Multiwall or hollow polycarbonate sheet has an internal cellular structure of ribs and channels, which traps air to improve thermal insulation and reduce weight while diffusing light, making it popular for skylights and large roofs.

Corrugated polycarbonate sheet is profiled into waves so it aligns with metal roofing profiles, which makes it the go-to choice for pitched roofs, carports, and pergolas where it must interlock with existing sheeting. Choosing among the three comes down to the balance of clarity, insulation, and roof profile that a project needs.

Key Properties That Matter

The performance of a polycarbonate sheet rests on a handful of properties. Light transmission is high, commonly around 88 to 90 percent for clear solid grades, so spaces stay bright without glass. The material holds up across a wide temperature range, roughly minus 40 to about 120 degrees Celsius in continuous service, which suits Malaysia's heat.

Fire behaviour is another advantage. Polycarbonate is inherently slow to burn and many grades self-extinguish once a flame is removed, a property measured by the UL 94 flammability tests for plastics. The one caveat is ultraviolet exposure: raw polycarbonate degrades under prolonged sun, so outdoor sheets carry a UV-protective coating on one or both faces. As a broad guide to polycarbonate properties and applications notes, UV-stabilised grades retain their strength and clarity for many years outdoors, which is essential for the Malaysian climate.

Applications Across Malaysia

The combination of strength, light, and weather resistance makes polycarbonate sheet a default choice for many building elements. It roofs skylights, walkways, carports, patios, and pergolas, forms awnings and canopies, and glazes greenhouses, factory roof lights, and partition walls, while also serving as machine guarding and safety glazing. Its appeal in Malaysia is practical: heavy monsoon rain, intense sun, and the risk of falling debris all favour a roofing material that will not shatter, while high light transmission keeps naturally lit spaces bright and lowers daytime lighting needs.

Polycarbonate Sheet Price in Malaysia

Polycarbonate sheet prices in Malaysia vary with type, thickness, size, and UV coating. As a rough guide, thin solid sheets in common sizes start from tens of ringgit per panel, while thicker solid sheets, larger multiwall panels, and premium UV-coated grades run into the hundreds of ringgit each. Standard panels are frequently supplied in a 4 foot by 8 foot format, with thickness typically ranging from around 2 mm up to 15 mm. Treat these figures as indicative, since a UV-coated, virgin-resin sheet costs more upfront but lasts far longer outdoors than a cheaper uncoated or recycled panel.

How to Choose the Right Sheet

Selecting a polycarbonate sheet comes down to matching form and grade to the job. Pick solid sheet where clarity and maximum strength matter, multiwall where insulation and light weight are priorities, and corrugated where the panel must match a roofing profile. Then set the thickness to suit the span and load, confirm the sheet carries a UV-protective coating for any outdoor use, and check the grade is virgin resin rather than recycled for the best durability and clarity. Working through these points prevents the common mistake of fitting an uncoated or under-thick sheet that yellows or sags in the tropical sun.

Sourcing Polycarbonate and Engineering Resins in Malaysia

Choosing the right sheet is one part of the task; sourcing quality material and the resins behind it from a dependable partner is the other. Manufacturers and fabricators in Malaysia benefit from a single accountable point of contact for engineering plastics, high-performance materials, and technical guidance.

Frequently Asked Questions

How much does a polycarbonate sheet cost in Malaysia?

Prices vary with type, thickness, size, and UV coating. Thin solid sheets in standard sizes start from tens of ringgit per panel, while thicker solid, larger multiwall, and premium UV-coated sheets can cost into the hundreds of ringgit each. Always confirm current pricing with the supplier, as resin grade and coating change the figure.

What is the standard size of a polycarbonate sheet in Malaysia?

The most common panel size is 4 feet by 8 feet, with thickness typically ranging from around 2 mm to 15 mm depending on the grade and application. Multiwall sheets are also supplied in longer roofing lengths.

What is the difference between solid and hollow polycarbonate sheet?

Solid sheet is a single dense layer with the highest clarity and strength, best for glazing and security. Hollow or multiwall sheet has an internal cellular structure that improves insulation and reduces weight, making it better for skylights and large roofs where light diffusion and heat control matter.

Is polycarbonate better than acrylic or glass?

For impact resistance, yes: polycarbonate is far tougher, at roughly 250 times the impact resistance of glass and around 30 times that of acrylic. Glass offers better scratch resistance and acrylic slightly higher clarity, so the best choice depends on whether strength, clarity, or scratch resistance matters most.

Does polycarbonate sheet turn yellow in the sun?

Uncoated polycarbonate can yellow under prolonged ultraviolet exposure, which is why outdoor sheets carry a UV-protective coating. A UV-coated, virgin-resin sheet resists yellowing and retains its clarity and strength for many years in the Malaysian climate.
