As a seasoned supplier of lamp cover plastic, I've witnessed firsthand the evolution of materials used in this industry. The choice of material for lamp cover plastic is crucial as it directly impacts the lamp's performance, durability, and aesthetic appeal. In this blog, I'll delve into the various materials commonly used to make lamp cover plastic, their properties, and applications.
Polycarbonate (PC)
Polycarbonate is one of the most popular materials for lamp cover plastic due to its exceptional properties. It is a thermoplastic polymer known for its high impact resistance, optical clarity, and heat resistance. PC lamp covers can withstand significant physical stress without cracking or breaking, making them ideal for both indoor and outdoor lighting applications.
One of the key advantages of polycarbonate is its excellent light transmission. It allows a high percentage of light to pass through while diffusing it evenly, reducing glare and creating a soft, pleasant illumination. This property makes PC lamp covers suitable for a wide range of lighting fixtures, including pendant lights, wall sconces, and outdoor floodlights.
In addition to its optical properties, polycarbonate is also resistant to UV radiation. This means that PC lamp covers won't yellow or degrade over time when exposed to sunlight, ensuring long - term performance and maintaining the lamp's appearance. Many outdoor lighting fixtures, such as streetlights and garden lights, benefit from the UV - resistant nature of polycarbonate.
Polycarbonate can be easily molded into various shapes and sizes, offering designers great flexibility. Whether it's a simple cylindrical shape for a T8 tube or a complex geometric design for a modern chandelier, PC can be formed to meet the specific requirements of the lighting fixture. You can find high - quality T8 Tube Plastic Cover made from polycarbonate at T8 Tube Plastic Cover.
Acrylic (PMMA)
Acrylic, or polymethyl methacrylate (PMMA), is another widely used material for lamp cover plastic. It is known for its outstanding optical clarity, often referred to as "organic glass." Acrylic has a high light transmittance rate, even higher than that of glass in some cases, which makes it an excellent choice for applications where maximum light output is desired.
One of the main attractions of acrylic is its aesthetic appeal. It has a smooth, glossy surface that gives a luxurious and modern look to lighting fixtures. Acrylic lamp covers can be polished to a high shine, enhancing the overall appearance of the lamp. They are commonly used in high - end residential and commercial lighting, such as designer pendant lights and display lighting.
Acrylic is relatively lightweight compared to glass, which makes it easier to handle and install. It is also more impact - resistant than glass, reducing the risk of breakage during transportation and installation. However, it is not as impact - resistant as polycarbonate, so it may not be the best choice for applications where the lamp cover is likely to be subjected to heavy impacts.
Acrylic can be fabricated using various techniques, including casting and extrusion. Extruded acrylic profiles are commonly used in the lighting industry for creating linear and tubular lamp covers.

Polypropylene (PP)
Polypropylene is a versatile thermoplastic polymer that is often used in lamp cover plastic, especially for more cost - effective applications. It is known for its chemical resistance, low density, and good mechanical properties.
PP lamp covers are lightweight, which makes them easy to install and reduces the overall weight of the lighting fixture. They are also resistant to many chemicals, including acids and alkalis, making them suitable for use in industrial and harsh environments.
One of the advantages of polypropylene is its flexibility. It can be bent and shaped without cracking, which allows for the creation of unique and innovative lamp cover designs. However, PP has a lower heat resistance compared to polycarbonate and acrylic, so it may not be suitable for high - temperature lighting applications.
PP is commonly used in mass - produced lighting fixtures, such as ceiling lights and some types of fluorescent tube covers. For example, T5 tube plastic covers made from polypropylene can offer a cost - effective solution for lighting systems. You can explore T5 Tube Plastic Cover to see the options available.
Polystyrene (PS)
Polystyrene is a widely used plastic material that is relatively inexpensive and easy to process. It is available in two main forms: general - purpose polystyrene (GPPS) and high - impact polystyrene (HIPS).
GPPS is known for its high transparency and good electrical insulation properties. It is often used in lamp covers where a clear and inexpensive option is required. However, GPPS is brittle and has poor impact resistance, so it is mainly used in low - stress applications.
HIPS, on the other hand, has improved impact resistance compared to GPPS. It is a blend of polystyrene and rubber, which gives it better toughness. HIPS lamp covers can withstand some degree of physical stress, making them suitable for a wider range of applications.
Polystyrene lamp covers are commonly used in simple and inexpensive lighting fixtures, such as some types of table lamps and small decorative lights. However, due to its relatively low heat resistance and mechanical properties compared to polycarbonate and acrylic, its use is more limited in high - end and high - performance lighting applications.
Factors Influencing Material Selection
When choosing the material for lamp cover plastic, several factors need to be considered.
Lighting Requirements: The type of light source and the desired lighting effect play a significant role. For example, if the goal is to achieve maximum light output with minimal glare, materials like acrylic or polycarbonate with high light transmission and good diffusion properties are preferred. If the light source generates a lot of heat, a material with high heat resistance, such as polycarbonate, should be chosen.
Environmental Conditions: For outdoor lighting, materials that are resistant to UV radiation, moisture, and temperature variations are essential. Polycarbonate and some specially treated acrylics are well - suited for outdoor applications. In industrial environments where chemicals may be present, polypropylene or other chemically resistant materials are a better choice.
Cost: Cost is always a consideration, especially for mass - produced lighting fixtures. Polystyrene and polypropylene are generally more cost - effective options compared to polycarbonate and acrylic, making them suitable for budget - conscious projects.
Design and Aesthetics: The desired shape, size, and appearance of the lamp cover also influence the material selection. Materials like polycarbonate and acrylic can be molded into complex shapes, allowing for more creative and modern designs.
Conclusion
As a lamp cover plastic supplier, I understand the importance of choosing the right material for each lighting application. Polycarbonate, acrylic, polypropylene, and polystyrene each have their own unique properties and advantages, and the selection depends on a variety of factors such as lighting requirements, environmental conditions, cost, and design.
