Packaging & Delivery
- Standard packaging: In 15Kg/20Kg PP woven bags with inner separate 1Kg small bag.
- OEM or neutral packaging available upon request
- Minimum Order Quantity (MOQ): 3 metric tons.
- Typical lead time: 7–15 days after order confirmation
- Trade terms: FOB / CIF / DDP under Incoterms® 2020
Storage and Shelf life
- Store in a dry and cool place.
- High humidity and temperature increase the risk of caking.
- Do not stack pallets on top of each other to avoid compaction.
- “Best use before end” date is on the label; storage beyond it doesn’t necessarily mean unusable, but required properties must be checked for quality assurance.

Alkali-Resistant Glass Fiber (AR Glass Fiber) is primarily used to reinforce cement-based concrete and mortars. It helps control cracking caused by plastic shrinkage, thermal shrinkage, and drying shrinkage, improving the crack resistance of cement-based materials.
Cement hydration produces calcium hydroxide (Ca(OH)₂), creating an alkaline environment that can damage ordinary glass fibers. Alkali-resistant glass fiber is specially designed to resist this alkaline corrosion, making it suitable for reinforcing cement-based concrete.
Calforce® Glass Fiber is supplied in 15 kg or 20 kg PP woven bags with separate 1 kg inner bags. Customized packaging is also available upon request. The product should be stored in a cool, dry place away from moisture. The recommended use-by date is indicated on the product label.
