Adhesive Films for Fabric-Foam Bonding
Product catalog summary
Overview: This document provides technical specifications and properties of adhesive films designed for fabric-foam bonding, produced by Collano Adhesives AG. The focus is on smart bonding solutions using various chemical bases.
Product Specifications:
- Chemical Basis: The adhesives are based on EVA, PP, and TPU.
- Melting Range: Varies from 60–150°C depending on the product.
- Melt Flow Index: Ranges from 5–40 g/10 min, indicating the flow characteristics of the melted adhesive.
- Density: Between 0.90 and 1.19 g/ml.
- ECO-Passport: Some products are certified, indicating environmental compliance.
- Open Time: Less than 1 second for most products, up to 15 seconds for others.
- Heat Deflection Temperature: Ranges from 50 to 135°C.
- Plasticizer Resistance: Present in TPU-based products.
- Mechanical Properties: Includes shear modulus, modulus of elasticity, yield stress, tensile strength, and ultimate strain, with significant variation across products.
Bonding Parameters:
- Pressing Time and Pressure: Consistent at 1 minute and 3 bar across all products.
- Minimum Bond Line Temperature (MBT): Ranges from 80 to 135°C.
- Pressing Temperature: MBT plus 10°C.
- Adhesive Film Weight: Generally 50 g/m², with one product at 60 g/m².
Performance on Substrates:
- Test Substrates: Includes cotton, polyester fabric, and Lycra.
- Peel Strength: Measured at various temperatures, indicating the strength of the bond.
- Adhesion to Foams: Varies by foam type (PE, PP, PET, PU) and product, with ratings of good, useful, or weak bonding.
Additional Notes:
- Products are available in different forms, such as blown film on carriers or flat die extruded film.
- Some products feature a matte finish and anti-block properties.
