Packing and Storage
Packaging Options: 25kg/bag PP valve bag with PE inner bag | 550kg super sack PP bag with PE inner bag and more.
Shelf Life: Shelf-life of two years; it can still be used if qualified by inspection after the shelf life.
Should be kept away from flames and other sources of heat. The Product should be stored in a cool and ventilated area. Adequate precautions should be taken to keep all dust levels below values that are hazardous to health and safety. In case of eye or skin contact, eyes should be flushed immediately with fresh water to remove dust particles, and affected skin areas should be washed with soap and water.
Frequently Asked Questions (FAQ)
What is FINE ACM impact modifier used for?
FINE ACM is primarily used as an impact modifier for producing opaque PVC products, including PVC pipes, fittings, profiles, siding, and rigid sheets, enhancing toughness and low-temperature impact strength.
What is the difference between ACM-24 and ACM-69?
ACM-24 is designed to replace CPE+ACR combinations with lower dosage while offering higher processability. ACM-69 is formulated to replace CPE+AIM combinations, providing superior surface glossiness, higher hardness, and higher Izod impact strength.
How does ACM compare with traditional CPE impact modifiers?
Compared to CPE, ACM offers superior toughness, better weather resistance, improved surface glossiness, and enhanced fusion properties due to its advanced IPN (Interpenetrating Polymer Network) molecular structure.
What are the available packaging sizes for FINE ACM?
FINE ACM is standardly available in 25kg PP valve bags with PE inner lining, as well as 550kg super sack PP bags with PE inner lining. Customized packaging options are also available upon request.
What is the shelf life and proper storage condition for FINE ACM?
FINE ACM has a shelf life of 2 years. It should be stored in a cool, ventilated area away from direct heat sources and open flames. Products beyond shelf life can still be used if re-inspected and verified qualified.
