TISSU DE SURFACE EN FIBRE DE VERRE SAST5O-W (50 g/m²)
Les voiles à faible résistance absorbent la résine trop lentement, laissent des traces blanches et sèches et se rompent sous une forte tension d'enroulement. Le SAST5O-W utilise une nappe de verre robuste de 50 g/m² qui absorbe la résine en moins de 5 secondes, scelle les parois internes des tubes et empêche les ruptures de ligne lors des enroulements rapides.

SAST5O-W FIBERGLASS SURFACE TISSUE (50g/m²)
Zero Line Snaps. Fast 5s Resin Soak.
SAXOBRAN® Our team designed SAST5O-W because we saw pipe plants scrap wrapped spools when surface tissue snaps on fast mandrels. We found that low-tensile veils soak resin too slow, leave dry white spots, and break under high winding pull. SAST5O-W uses a strong 50g/m² glass web to soak resin in under 5 seconds, seal inner pipe walls, and stop line breaks on fast winding lines.
Industrial Pain Points Solved
Web Snapping Under High Winding Tension
Fast winding mandrels pull tissue hard. Low-grade veils snap at high line speeds, forcing worker teams to stop machines, re-thread rolls, and toss out damaged pipe sections.
Built with high Machine Direction tensile strength (≥120 N/50mm).Pulls smooth over tension rollers at high winding speeds without edge tears or web breaks.
Slow Resin Penetration and Dry Air Pockets
Dense binders block liquid resin on fast lines. Dry fiber spots form air pockets, causing pipe inner liners to leak under water pressure testing.
Engineered with a fast-dissolving binder system (≤5s penetration time).Lets polyester and vinyl ester resins flood the web fast, driving out trapped air.
Engineered Characteristics
Resin-Rich Inner Liner Seal
Hides structural glass fibers on inner pipe walls to form a smooth, leak-proof barrier.
Ultra-Fast Resin Soak
Soaks liquid resin in under 5 seconds to stop dry spots on fast continuous winding lines.
High Tension Line Stability
Withstands heavy continuous pulling force without stretching, wrinkling, or splitting.

Processing, Packaging & Logistics Quality
1
Temperature Range
Store rolls in dry indoor rooms kept between 10°C and 30°C.
2
Humidity Limits
Keep relative humidity below 65% so binders stay dry and stable.
3
Stacking Security
Do not stack pallets more than 2 layers high to keep paper cores round.
Global Supply Chain Securement
Roll & Core Construction: Wound tight on heavy-duty 3-inch solid paper cores to stop core crush.
Sealed Barrier Packaging: Wrapped in thick PE stretch film to block moisture, dust, and sea air during shipment.
Anti-Shifting Loading: Fixed on export wooden pallets with corner guards and tight plastic strapping.
Technical Q&A
Q: What is the fundamental difference in design logic between this model and the standard or general-purpose models within this category?
A: General surface veils (like 30g/m² or 40g/m²) are made for light FRP hand lay-up or mold pressing where tension is low. SAST5O-W is a 50g/m² tissue built specifically for high-speed continuous pipe winding. It offers higher MD tensile strength (≥120 N/50mm) and ultra-fast resin penetration (≤5s), so it won't break or leave dry spots on fast mandrels.
Q: In actual operation, how can this model be utilized to achieve optimal performance?
A: Feed SAST5O-W directly onto the rotating mandrel as the first layer before winding glass roving. Keep unwind tension steady across the full roll width. Ensure resin bath temperature stays between 20°C and 30°C so resin drenches the tissue in under 5 seconds before structural roving wraps over it.
Q: What are the shelf life and storage limitations after opening the original packaging?
A: Once you open the PE film seal, use the roll within 24 hours. Glass tissue absorbs air moisture quickly in humid plants. If tissue moisture rises above 0.2%, resin soak slows down, causing air voids and pinhole leaks inside the pipe liner. Always wrap open rolls back in PE plastic film.
