STRECH
CORDEX
THREE LAYERS
- UV stabilizer added to the three layers (high concentration in the outer layers and lower concentration in core layer)
- Cling agent added in the two outer layers
- Uneven distribution of cling agent and UV stabilizer may occur in the outer layers
- High concentration - rupture due to cluster points and poor unwinding
- Low concentration - bad sealing and premature failure
- Mechanical reinforcement possible in the core layer
FIVE LAYERS CORDEX
Optimized layer construction and functionality
- Optimized concentration of
- anti-UV for better weatherability
- Preferential concentration of cling agent on the outer layers for a better sealing
- Improved mechanical resistance in the core layer
- Improved barrier properties by chemical and physical modification of the middle layers
