Polycarbonate injection molding uses the thermoplastic resin to transmit light and maintain shatter resistance. The amorphous material performs in extreme heat and can have an impact strength 250 times greater than glass and 30 times greater than acrylic.
Various industrial grades of polycarbonate are produced by the addition of fillers to meet unique needs. Without the addition of UV stabilizers the material can degrade or haze when exposed to UV light. It can also scratch more easily than other thermoplastic materials.
The grades can be differentiated by the amount of glass fiber reinforcement and variants in melt flow. The material can be modified for specific uses. For example, the addition of flame retardants can prevent the spread of fire, making polycarbonate extremely attractive in industries such as electronics when flames are a threat to performance.
Injection molding polycarbonate lenses may include the addition of ultraviolet stabilizers for protection from UV light degradation. Polycarbonate injection molding may also include the addition of mold release agents to lubricate the material during processing.
Polycarbonate injection molding produces parts that are extremely durable in consumer and industrial applications. Although not produced through plastic injection molding, the best example of this material’s unparalleled impact resistance is its use in bulletproof glass.
While polycarbonate is highly impact-resistant and can transmit light, this widely used thermoplastic is also:
From a price standpoint, polycarbonate is slightly higher in cost than acrylic.
Polycarbonate is found in many industries, including automotive, electrical, transportation and consumer goods. Popular applications include:
