Core Advantage
Outstanding flame retardant and smoke suppression performance: Phenolic resin itself is a difficult-to-burn resin system. When exposed to fire, it forms a dense carbonized layer, which can effectively block the transfer of oxygen and heat. At the same time, it has extremely low smoke emission and the release of toxic gases is far below industry standards, giving it significant advantages in scenarios with strict fire safety requirements.
Excellent high-temperature stability: It can maintain structural and performance stability for a long time in an environment below 200℃, and can withstand temperatures above 300℃ for a short period. Even after being exposed to high-temperature open flames, it can still maintain a certain mechanical load-bearing capacity, making it suitable for high-temperature working conditions.
Balanced mechanical properties: Relying on the reinforcing effect of the reinforcing fibers, the product features high tensile strength, flexural modulus and interlaminar shear strength, which can meet the load-bearing requirements of structural components. At the same time, it has excellent impact resistance and fatigue resistance.
Flexible molding adaptability: Compatible with various mainstream processes such as autoclave molding, compression molding, and vacuum bag molding, the molding cycle is controllable, the products have high dimensional accuracy and good surface finish, and can be adapted to the processing and production of complex and irregular-shaped parts.
Environmental compliance attributes: There is no significant evaporation of harmful solvents during the production process. The finished products comply with multiple international environmental protection standards such as RoHS and REACH. Moreover, after being discarded, they can be treated harmlessly through specific processes, aligning with the concepts of green manufacturing and sustainable development.
Customized service capability: According to the application scenarios of customers, we can flexibly adjust the resin system formula, reinforcing fiber type and layup method, provide exclusive product solutions, and meet the personalized needs of different industries.

FAQ
1. What are the storage conditions for phenolic resin-based prepregs?
This product should be stored in a sealed container in a low-temperature environment. The recommended storage temperature is -18 ℃ to 0℃. The storage period varies from 3 to 6 months depending on the resin system. After opening, it should be used as soon as possible. Any unused part needs to be resealed and returned to a low-temperature environment to prevent the resin from curing prematurely or absorbing moisture, which may affect its performance.
2. What molding processes can be adopted for this product? What requirements are there for the forming equipment?
It is compatible with conventional composite material forming equipment such as autoclaves, molding machines, and vacuum bag presses. If autoclave molding is adopted, it is recommended that the molding temperature be 120℃ to 160℃, the molding pressure be 0.3 to 0.6MPa, and the holding and pressure holding time be adjusted to 1 to 3 hours according to the thickness of the product. Compression molding can appropriately increase the pressure according to the size of the mold to ensure the density of the product. Specific process parameters can be customized and guided by our technical team.
3. What are the core differences between phenolic resin-based prepregs and epoxy resin-based prepregs?
The core difference between the two lies in the focus of performance: epoxy resin-based prepregs have better mechanical strength and adhesion, but their flame retardancy and high-temperature resistance are relatively weak. Phenolic resin-based prepreg materials mainly feature flame retardancy, low smoke, and high-temperature resistance, and also possess certain mechanical load-bearing capacity, making them more suitable for fire safety and high-temperature working conditions. In contrast, epoxy resin prepreg materials are more appropriate for conventional working conditions with extremely high requirements for structural strength.
4. Is product customization supported? How long is the customization cycle?
Supports full-dimensional customization, including resin formula, type and specification of reinforcing fibers, resin content, surface density, product width, etc. The delivery cycle for regular customized products is 7 to 15 working days. Special customized solutions can be negotiated and determined based on actual needs, and small-batch sample services are also available.
