What should be generally borne in mind (drying, cleanliness, conveying) when processing PLEXIGLAS® molding compound?
A high standard of cleanliness should be observed at all processing machines and downstream equipment. There is a risk of feedstock contamination with dust and foreign material particularly during conveying and drying. Only filtered air should be used for conveying the molding compound, and the air that enters the pipe subsequently must also be filtered. Aluminum pipes and hoppers are unsuitable owing to material abrasion. Only stainless steel components should be used in conveyor equipment.There is usually no need to predry PLEXIGLAS®, provided it has been stored in a dry place for not too long (up to six months). Corresponding temperatures and drying times can be taken from the respective product information leaflets.
