Common materials for plastic lamp housings include polyvinyl chloride (PVC) alloys, polycarbonate, polymethyl methacrylate (PMMA), PVC, polystyrene, and polyethylene. These materials are widely used in lamp housing manufacturing due to their excellent light transmittance, water resistance, durability, ease of molding, easy coloring, aging resistance, light weight, and low cost.
Plastic lamps have the following advantages:
Good chemical stability: Plastic lamps are resistant to acids, alkalis, and chemical corrosion, making them suitable for various environments.
Excellent flame retardant properties: The chlorine in PVC plastic makes it an excellent flame retardant material, with a high oxygen index and FV0 flammability rating, improving safety.
Long service life: PVC is not prone to aging when used outdoors, and its service life can reach over 20 years.
Good low-temperature resistance: Modified PVC alloys can be used normally below 30℃, adapting to various low-temperature environments.
High impact resistance: By adding low-temperature resistant synthetic materials and impact-resistant agents, the impact resistance of modified PVC alloys is significantly improved, enhancing the durability of the lighting fixtures.
Good waterproofing: PVC has strong polarity and good compatibility with various adhesives, ensuring the watertightness and airtightness of the lighting fixtures, making them suitable for humid environments.
