During the creation of the item referred to as auto lamp molding plastic, its creators used a number of very important materials. Typically, these resources must be both safe and hard-wearing. Common materials used for automotive lighting include:
Polycarbonate (PC)
Polycarbonate is one of the most frequently used materials for auto lamp molding because of its durability and high impact resistance. PC is a transparent thermoplastic, which means it can be molded easily into complex shapes while maintaining its clarity. This property makes it ideal for headlight lenses and other transparent automotive parts. Additionally, polycarbonate can withstand extreme temperatures and is resistant to UV light, which ensures that it will not darken or degrade over time when exposed to sunlight.
Acrylonitrile Butadiene Styrene (ABS)
ABS is widely used because it is easy to mold and paint. Acrylonitrile Butadiene Styrene (ABS) is a favored material in automotive lamp housings and reflectors. Its rigidity and resistance to chemical exposure make it suitable for parts that need to maintain structural integrity over time. ABS can also be easily painted, allowing for parts that match the vehicle’s aesthetic design. Often, the combination of ABS with polycarbonate, known as ABS-PC blend, is employed to harness properties from both plastics.
Poly(methyl methacrylate)
Known as PMMA or acrylic, poly(methyl methacrylate) is a transparent thermoplastic that is frequently used as an alternative to glass in vehicle tail lights and turn signals. PMMA provides exceptional clarity and weather resistance, making it suitable for applications where light transmission is critical. This plastic also offers good scratch resistance, though it is less impact-resistant compared to polycarbonate. Despite the need for a protective coating to enhance its durability, PMMA remains a popular choice for its aesthetic qualities.
Thermoplastic Elastomers (TPE)
These materials combine rubber-like flexibility with plastic properties, making them ideal for gaskets, seals, and light covers. TPEs have excellent rebound properties and can withstand a wide range of temperatures, which makes them suitable for lighting components that may experience varying heat levels.
Polyethylene Terephthalate Glycol-Modified
Polyethylene terephthalate glycol-modified (PETG) is a copolymer of polyethylene terephthalate (PET) modified by the addition of glycol. This helps in reducing the polymer's high tendency to form covalent bonds with itself, resulting in a highly moisture-resistant and easily recyclable material. Because of its inherent toughness and chemical resistance, PETG is commonly used for protective coatings and housings in automotive lighting.
