2. Why Compare Adhesives?
Adhesives are pivotal across industries, and choosing the right type is
crucial. This presentation delves into the performance of starch and
synthetic adhesives, comparing them across bonding strength, flexibility,
durability, environmental impact, cost-effectiveness, and application
versatility. Discover which adhesive suits your needs best!

3. Bonding Strength:
Starch vs. Synthetic
Starch Adhesives:
Performance: Excellent for paper and cardboard,
with strong initial tack and robust adhesion.
Applications: Ideal for packaging, bookbinding,
and cardboard products.
Synthetic Adhesives:
Performance: Superior bonding strength for
plastics, metals, and ceramics.
Applications: Essential for high-performance needs
in automotive and aerospace industries.

4. Flexibility Face-Off:
Which Adapts Best?

5. Starch Adhesives:
Characteristics:
Naturally flexible, allowing them to accommodate the expansion and contraction
of materials. This flexibility helps maintain bond integrity over time and under
varying conditions.
Best Use:
Bookbinding and Paper Products: Ideal for applications where materials might
shift or expand due to environmental changes. Starch adhesives are
commonly used in bookbinding and packaging where flexibility ensures
durability and reliability.
Eco-Friendly Packaging: Useful in packaging solutions where the ability to
handle material movement and changes in temperature is crucial. Their
flexibility aids in creating strong and adaptable packages that perform well in
diverse conditions.

6. Synthetic Adhesives:
Characteristics:
Flexibility varies by type.
Polyurethane adhesives offer
high flexibility, which can
withstand significant
movement and stress, while
epoxy resins, though strong,
are typically less flexible and
more rigid.
Best Use:
Construction and Automotive Industries: Polyurethane
adhesives are preferred for applications in construction and
automotive sectors where flexibility is needed to
accommodate joint movements and thermal expansions.
These adhesives are essential for bonding materials that
experience frequent changes in stress and temperature.
High-Performance Applications: Epoxy resins and other
rigid synthetic adhesives are suitable for situations requiring
strong, permanent bonds where flexibility is less of a
concern, such as in structural applications or where
resistance to heavy loads and harsh conditions is required.

7. Durability Duel:
Starch vs. Synthetic
Synthetic adhesives generally offer superior durability for extreme conditions, though starch adhesives have significantly improved.

8. Environmental Impact
Starch adhesives are more
sustainable and eco-friendly
compared to synthetic adhesives,
which have a larger environmental
footprint.

10. Cost Comparison: Budget-
Friendly or Premium?
Starch Adhesives:
Cost: Generally lower due to less expensive raw
materials and simpler production.
Applications: Cost-effective for large-scale uses
like packaging and paper industries.
Synthetic Adhesives:
Cost: Higher due to complex formulations and raw
materials.
Applications: The higher cost is justified for high-
performance scenarios where superior adhesive
properties are essential.

13. Making the Right Choice:
Starch or Synthetic?
Starch adhesives offer cost savings, environmental benefits, and
versatility, especially for paper and cardboard uses. Synthetic
adhesives excel in strength, flexibility, and durability, making them
suitable for high-performance applications. Your choice will depend on
specific project needs, including performance requirements,
environmental concerns, and budget.
