Fire Retardent Polyester Resin
Fire retardent resins are essential for the mass transit market. Here we list our standard types, however we have access to a much broader range than listed and invite you contact us to determine if your requirements can be supplied.
The fire retardent resins listed below laminate well, have great physical performance and are price competitive. Additionally, we also offer fire retardant vinyl ester resins here.
| Poliset PS-820FR | Poliset PS-9583 | |
|---|---|---|
| Description | Poliset 820FR is fire retardent filled unsaturated polyester resin as orthophthalic type complies to Class 2 Surface Spread Of Flame (BS476 : Part7). | Reversol P-9583 is a filled, beige opaque fire retardant unsaturated polyester resin for use in contact moulding. |
| Application | Poliset 820FR is used for making a variety of glass fiber reinforced plastic such as water and storage tanks, septic tank, cooling tower, silo especially for Fire retardant requirement application. | PS-9583 has been specifically designed to meet the increasing demand for an inexpensive filled resin system with excellent fire retardant properties. Fully cured PS-9583 reinforced with glass fibre can obtain a class 1 surface spread of flame rating when tested to BS-476 Part 7 :1997, and class-0 when tested to BS-476 Part 6. |
| Benefits | Good wet out and air release. Physical properties are very good as listed. | Compared to unfilled resin, it is necessary to use a slightly higher PS-9583 resin to glass ratio during FRP lamination. A resin to glass ratio by weight of 11 : 3 is recommended. PS-9583 resin should be use at above 23°C ambient working condition. To achieve optimum mechanical, weathering and fire retardant properties, it is recommended to post cure P-9583 laminates at 50oC for 15 hours, or allow minimum 7 days ageing at 28-33oC, before putting laminates into service. |
