The major constituent of laminate of safety glass, which holds the broken glass, pieces in their places during accident (and thus minimises the danger from flying glass fragments) is____________________?
Correct answer: C. Polyvinyl butyral
- A. Polyvinyl alcohol
- B. Polyvinyl acetate
- C. Polyvinyl butyral
- D. PVC
