Types of PMMA
PMMA can come in different variations, depending on its composition and intended use. Some common types of PMMA include the following.
Canyon Components strives to meet all customer service requests. Feel free to contact Canyon Components engineering and let our knowledgeable staff help you design the perfect part for your needs.
General Purpose PMMA
This standard type offers excellent clarity and light transmittance, comparable to glass. It's widely used in applications like display cases, lenses, and aquariums. Resistant to UV light and weathering, it's suitable for both indoor and outdoor applications, providing a balance between aesthetics and durability.
Impact-Modified PMMA
Enhanced for greater impact resistance, this PMMA variant is ideal for applications where durability is key, such as skylights, outdoor signage, and automotive tail lights. It maintains the clarity of standard PMMA while offering increased toughness against physical stress.
Heat-Resistant PMMA
Specially formulated to withstand higher temperatures, this type is used in applications like high-performance lighting fixtures and automotive components that are exposed to heat. It retains its shape and clarity under thermal stress, making it a reliable choice for heat-sensitive environments.
Extruded PMMA
This version is designed for ease of processing and is often used for producing sheets, tubes, and profiles. Extruded PMMA offers excellent surface finish and is commonly used in architectural applications, retail displays, and signage, where aesthetic appeal is essential.
Cast PMMA
Known for its superior optical properties and surface finish, cast PMMA is used in high-quality lenses, artistic installations, and precision engineering components. It offers greater flexibility in terms of size and thickness compared to extruded PMMA and provides exceptional clarity and light transmission.
UV-Curable PMMA
This innovative type is cured using UV light, resulting in enhanced mechanical properties and faster processing times. It's used in applications requiring rapid production, like coatings, adhesives, and dental applications. UV-curable PMMA is notable for its excellent clarity and resistance to yellowing over time.
