What material is the black plastic shell of the headlight?
1 Answers
The black plastic shell of the headlight is made of polycarbonate plastic. Reasons for using polycarbonate plastic: Compared to glass, plastic has strong elasticity. Under non-violent impact conditions, it has a buffering effect and is not easily broken. Even if it breaks, it causes much less harm to pedestrians or animals on the road than glass. Plastic is better than glass in terms of mechanical properties, strong plasticity, stable chemical properties resistant to acid and alkali corrosion, and light weight. Glass: In the past, vehicles used glass lamp covers mainly due to technological limitations at that time. The strength and transparency of plastic could not match the high transparency of glass, and it could not maintain its shape and color under strong light or high temperatures. Nowadays, plastic lamp covers can achieve the transparency and color stability of glass, and glass is significantly heavier than plastic.
