Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, presents our Low Flow Resin, 120°C Cure, 1.5m Roll Length Glass Fiber Woven Prepreg Tape. Engineered for demanding composite applications, this prepreg tape combines a controlled low-flow resin system with high-strength woven glass fiber, offering predictable wet-out and reduced waste during curing. Designed for users who require precise resin distribution and stable mechanical properties, this product is ideal for wrapping, laminating, and structural reinforcement.
Our prepreg tape is manufactured using advanced impregnation technology, ensuring consistent resin content and uniform fiber alignment. The low-flow resin formulation minimizes resin bleed-out, which is critical for maintaining dimensional accuracy and surface finish in complex molds. With a moderate cure temperature of 120°C, it balances energy efficiency with fast cycle times, making it suitable for both hand lay-up and automated processes.
Key features and benefits:
- Low Resin Flow: Reduces flash and waste, improves part-to-part consistency, and allows for cleaner handling.
- 120°C Cure Temperature: Compatible with standard oven and autoclave equipment, lower energy consumption compared to high-temperature systems.
- 1.5m Roll Length: Convenient for manual or automated dispensing, minimizes joints and splicing.
- Woven Glass Fiber Reinforcement: Provides excellent tensile strength, impact resistance, and dimensional stability.
- Customizable Width: Available in various widths from 10mm to 300mm upon request, tailored to your application.
- Consistent Resin Content: Typically 35%–45% resin by weight, optimized for low flow behavior.
- Long Out-Life at Room Temperature: Suitable for extended lay-up operations without refrigeration (actual out-life depends on storage conditions).

Application advantages: The low-flow characteristic of this prepreg tape is particularly beneficial for filament winding, pipe repair, and aerospace structurals where resin migration must be controlled. The 1.5m roll length reduces material waste and simplifies handling in manual operations. The woven glass construction provides excellent conformability to curved surfaces, while the 120°C cure allows for faster demolding and higher throughput.
Trust and reliability: With over 25 years of manufacturing experience, Anping County Boli Hardware Wiremesh Products Factory has been exporting to global markets including North America, Europe, Southeast Asia, and the Middle East. Our annual export value of US$5–10 million reflects our commitment to quality and customer satisfaction. We ship from multiple ports (Tianjin, Qingdao, Shanghai, Foshan) to ensure timely delivery. Every roll of prepreg tape is QC-tested for resin content, tack, and flow behavior before shipment.
Contact us today to discuss your specific width, weave pattern, or resin formulation requirements. We offer samples for evaluation and can customize the tape to meet your process parameters. Experience consistent quality and cost-effective solutions backed by a reliable manufacturer.
Frequently Asked Questions
-
Q: What is the recommended storage condition for this prepreg tape?
A: The tape should be stored in a freezer at -18°C or below to maximize shelf life. At room temperature (25°C), the out-life is approximately 14 days. Always seal the roll in a moisture-proof bag when not in use. -
Q: Can I cure this tape at a temperature lower than 120°C?
A: The resin system is optimized for 120°C cure. Lower temperatures may result in incomplete cure and reduced mechanical properties. If you need a lower temperature cure, we can offer alternative formulations upon request. -
Q: What widths are available for this product?
A: Standard widths include 50mm, 100mm, and 150mm. We can also provide custom widths from 10mm to 300mm. Please specify your requirement when ordering. -
Q: Is this tape suitable for high-temperature applications?
A: The cured composite can typically withstand continuous service temperatures up to 150°C (depending on the resin system). For higher temperature resistance, we can recommend a different resin formulation. -
Q: How long does the tape remain tacky at room temperature?
A: Tack life is approximately 7–10 days at 25°C, depending on humidity. For best results, use within 7 days of removal from cold storage. -
Q: Can I get a sample roll for testing?
A: Yes, we offer sample rolls (typically 0.5m length) for evaluation. Please contact our sales team with your intended application details. -
Q: What is the resin content of this tape?
A: The resin content is typically 38% by weight, with a tolerance of ±2%. This is optimized for low flow behavior. Adjustments can be made upon request. -
Q: Is this product RoHS compliant?
A: Yes, our raw materials are sourced to comply with RoHS regulations. Please request a certificate of compliance if needed.
