- Table 2 Varying flame retardants.
- Table 2 shows that the addition of flame retardant salts like Rimar (Cl) and KSS (C2) in combination with small quantities of anti drip (TSAN) result in V0 performance at 1.5 mm thickness, but have relatively poor transmission with values of 54 and 34% respectively.

Results presented in tables 2, 3 and 4 shows transmission depends largely on type of flame retardants used. Composition E12, E13 and E3 have substantially low halogen content.
