Through our sister company, MSI Technology L.L.C., we can help you select the proper adhesive resin for your applications. (MSI Technology markets Plexar® tie layer adhesive produced by LyondellBasell.) For details, contact your Soarus’ representative.
You should avoid using rapid compression type screws such as those used for nylon. There should be at least four turns in the compression zone; this number will vary slightly depending on the L/D and compression ratio. Trouble is particularly likely to occur on high revolution extruders equipped with rapid compression type screws with 1 – 3 turns in the compression zone. The recommended percentage of turns in each zone should be as follows: 30-40 % in the feed zone, 20-25 % in the compression zone and 35-50 % in the metering zone.
Recommended screws for SoarnoL™ have LD=24-30 and CR=3-3.5. Temperature conditions are generally 190-230deg C(374-446deg F).
In order to prevent thermal decomposition, please make sure the temperature does not exceed 250deg C(482deg F). For more information, see the Processing Technique page.
