FAQ
Is Butyraldehyde compatible with most common plastic drums for transport? Butyraldehyde is usually packed in carbon steel drums. Some plastic materials may swell or degrade under long contact, so drum material verification is required before shipment.
What storage requirements apply to Butyraldehyde? Store away from heat sources, oxidizing agents and strong acids. Keep containers tightly sealed in a cool well ventilated warehouse.
Can REACH registration documents be supplied together with shipment papers? REACH registration information can be provided. MSDS download is accessible for compliance checking before customs clearance.
