Low-smoke, low-toxicity, halogen-free, flame retardant, silane crosslinkable compound for the production of flexible heat shrinkable tubing. SX738 is a low smoke, low fume, fire retardant silane grafted compound, curable by exposure to moist conditions. This is designed specifically for the production, by extrusion, of flame retardant halogen free heat shrinkable tubing. The graft component SX738 is mixed with a crosslinking catalyst masterbatch CM424 generally in the ratio 95:5. The two component system SX738:CM424 combines ease of processing with the ability to achieve a degree of crosslinking compatible with good expansion and contraction. |

| Extrusion instructions |
|---|
| Many modern thermoplastic extruders will process the material although a screw designed to give good homogenisation without excessive shear (which could cause unacceptable increases in melt temperature) should be used. An extruder with an L/D ratio (length/diameter) of 15-24 and an extruder screw of compression ratio 2-3:1 are recommended. |
