GELS

摘要

Flame-retarded gels of oil-extended triblock copolymers are made with less than 40 % (pref. 35 %, 30 %) flame retardant additive while achieving at least 25 % (pref. 45 %, 65 %) reduction in burn rate under UL-94 Horizontal Burn Test. Preferred additives, e.g. char-forming and intumescent, esp. Phosphorous-containing, can achieve self-extinction of the test sample and non-ignition of cotton wool positioned 30 cm below the test sample (this being a modification of the above Test Method).
