PP resin (polypropylene resin) thermoplastic prepreg tapes are materials made by impregnating continuous fibers with polypropylene resin. These unidirectional tapes are used in various industries due to their lightweight, durable and versatile properties. They can be heat activated and are suitable for applications that require a high strength-to-weight ratio and resistance to chemicals.
Advantages of Choosing PP Resin as Matrix
- Thermal stability: PP resin can withstand high temperatures of about 100°C.
- Chemical stability: It has good resistance to many chemicals, such as acids and alkalis.
- Non-toxicity: PP resin does not contain hazardous substances, is colorless and odorless, and will not damage human health.
- Mechanical properties: PP resin has high strength and stiffness, especially at low temperatures.
- Lightweight: PP resin is lighter than water and has good specific strength.
