ebalta releases UL94 rated materials to RIM flame retardant range

18 May 2012

ebalta UK has introduced MG 321 FR-S, a polyurethane low-pressure reaction injection moulding (RIM) material that meets the high flammability specifications of specialised applications in the medical, automotive, rail vehicle and electronic data processing (EDP) sectors. The two-component, self extinguishing material is available in two colours, black or natural, and both colours are approved to the highest flammability standards of UL94.

Component produced from black MG321 FR-S, approved to UL94 V-0 and UL94 5VA

This self extinguishing MG 321 FR-S has a pot life of 50 – 60 seconds at 20ºC and a cure time of 15 – 20 minutes at 50 ºC. It exhibits a high heat resistance and a glass transition temperature, Tg of 133ºC.

MG 321 FR-S has been successfully market tested in the UK and approved for projects where the highest flame proofing was required. This material provides key flame retardant properties ensuring very low flame spread and minimal quantities of smoke or toxic fumes in the event of a fire.

Products approved to the more demanding UL94 5VA specification provide extra protection against the formation of holes appearing in test specimens and therefore in the manufactured components produced in these materials.

MG 321 FR-S is available from stock in matched mix ratio pack sizes of 200kg / 100kg and 20kg / 10kg for next day delivery within the UK market.
