Title: Non-smouldering latex foam rubbers
IPC: C08J9/30
Filed: 1982-03-25
Abstract: A latex foam rubber which is non-self-propagating when subjected to the "cigarette" test (B.S.S. 5852, Part I, 1979) is produced from a formulation containing from 0 to 25 parts by weight natural rubber, from 75 to 100 parts by weight styrene/butadiene (S/B) rubber, accelerators, fillers and 1 part by weight or less per hundred parts rubber of elemental sulphur which may be present per se or derived from a sulphur-donor compound. Restriction of the sulphur level, especially in foam rubbers containing relatively large amounts of S/B rubber, leads to a product which passes the said B.S.S. test, where a mere conventional amount of sulphur (e.g. 2-2.5 parts) would lead to failure. Any slight deterioration in the physical properties of the product can be redressed by including up to 25 phr (e.g. 10-1 5 phr) of polystyrene or a "high-styrene" S/B resin latex in the formulation.
