Product Applications
PVA Fiber is suitable for cement-based and construction material systems that require reinforcement, crack resistance, toughness improvement, and better durability. Typical uses include:
Fiber cement boards, colored tiles, cable pipes, and lightweight partition panels as an eco-friendly asbestos replacement material
Mass concrete casting for demanding projects such as airport runways, highways, parking areas, dams, port piers, bridge panels, high-rise slabs, and swimming pools
Roofing, basement, and wall plastering mortar in industrial and civil construction applications
Shotcrete applications for tunnels, culverts, channels, slopes, and mine walls
Plaster products, magnesite products, dry powder construction materials, rubber products, and plastic goods requiring reinforcement performance
Coastal areas, saline-alkali environments, and chemically corrosive fields where higher durability is needed

●Estimating Data:
The dosage rate is dependent on the application . The general dosage range is 900g/m3 .
Using Instruction:
(1)Length : generally 12mm.
(2)Mixing Process: Crushed stones, fibers and sands are put into the mixer in succession . After stirring for two minutes, fiber willfully spread and then add cement and water and stir normally. The addition of materials also can be put into as usual , but the stirring time should be properly prolonged to more than 4 minutes to make fiber completely mixed.
(3)Shaping & Maintenance: There is no special requirement, may prolong the vibrating time for 30s. The maintenance of the fiber concrete should be done same as the normal concrete .

Packaging & Delivery
- Standard packaging:25 kg net paper bags or on cIients’ requirement
- OEM or neutral packaging available upon request
- Minimum Order Quantity (MOQ): 3 metric tons.
- Typical lead time: 7–15 days after order confirmation

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.

SE-22 is a Hydroxypropyl Starch Ether (HPS) additive designed for building dry-mix systems to improve workability (constructability), provide good sag resistance, and enhance wettability for smoother application and finishing.
SE-22 is suitable for dry-mix building formulations such as tile adhesives, mortars, plasters/renders, and roller plasters, and related construction mixes.
SE-22 provides sag resistance (anti-sag), helping the mix hold on vertical surfaces and improving application stability during troweling/spreading.
