Product Information
Full details
The Polyvance FiberFlex R10-04-04-BK is designed for professional technicians and DIY enthusiasts who need a reliable, universal solution for repairing automotive and industrial plastics. Its primary benefit is the ability to bond to difficult plastics like polypropylene and TPO without requiring the user to identify the specific base material, saving significant prep time. While it offers superior adhesion and a flat-profile design to prevent curling, users should note that it is intended for use with a dedicated plastic welding system, such as an airless, hot-air, or nitrogen welder.

FAQs
Do I need to identify the plastic code before using this rod?
No, FiberFlex is designed as a universal rod specifically to eliminate the need for plastic identification.
Can I use this with a standard soldering iron?
While it may melt, it is strongly recommended to use a dedicated plastic welding tool for proper temperature control and bonding strength.
How many rods are included in a 1 lb. package?
There are approximately 80 rods per 1 lb. package.
Is this rod compatible with nitrogen welders?
Yes, FiberFlex is compatible with airless, hot-air, and nitrogen plastic welding systems.
What is the physical size of each rod?
Each rod is 12 inches long, 3/8 inch wide, and 1/16 inch thick.
Troubleshooting
The rod is curling while welding
Ensure you are using a consistent feed rate and that your heat source is not creating an excessive melt zone beyond the rod width.
Rod is not adhering to the surface
Check that the surface has been properly sanded and cleaned of paint, oils, or mold release agents before welding.
Excessive smoke during repair
Your welder temperature is likely set too high; lower the temperature slightly to ensure a melt rather than a burn.
Pros and Cons
Pros
- No need to identify the specific plastic type before starting
- Provides excellent adhesion to difficult substrates like TPO
- Resists curling due to the engineered square-edge profile
- Works with most standard plastic welding equipment
- Large 1 lb. package provides high value for frequent users
Cons
- Requires professional or high-quality plastic welding equipment
- Not suitable for use with standard soldering irons
- Requires specific surface preparation to achieve maximum bond strength
Setup, Compatibility & Care
To begin, ensure the damaged area is cleaned thoroughly with a plastic cleaner and beveled using a grinder or rotary tool to create a V-groove. FiberFlex is compatible with any airless, hot-air, or nitrogen plastic welding system capable of reaching the necessary melting point of the resin. For optimal care, store the rods in a cool, dry place to prevent moisture absorption or contamination. When working, always ensure proper ventilation, as heating plastic releases fumes.
