Maxxam ™ SY 89-21-1 is a polypropylene copolymer compound with a pre-dispersed blowing agent for up to 50% expansion. The compound offers consistent cell structure, dielectric properties, and strength on insulation walls as thin as 10 mils. NOTE: 1. Typical properties of molded slab (0.075); Not to be construedas specifications.2. Foam density reduction depends upon loading level, temperatureand residence time before cooling.3. Recommended process temperature: 190°C to 220°C (375°F to430°F). Information provided by PolyOne |
