Rubber adhesives are made from natural or synthetic rubber resins. Individual elements do not change, the components are mixed to produce an adhesive.
Rubber adhesives have:
- High initial adhesion
- Some adhesion buildup – 50% at 20 min, 80% at 24 hours, 100% at 72 hours
- Good flexibility
- Moderate temperature resistance
- Moderate durability
Where do you find Rubber adhesives - most masking tapes (paper), most packaging tapes (plastics), vinyl, and plastic backing? Rubber Adhesives are best when you want quick adhesion and maximum holding power in the shortest amount of time. Consider Double Coated tapes when you need a quick bond to paper and paper board, or most fiber-based products.
Acrylic adhesives are a type of synthetic, polymer-based adhesive that are known for their strong bonding properties and good weather resistance. Acrylic adhesives can be formulated to produce specific high-performance characteristics.
Acrylic adhesives have:
- Fair initial adhesion
- Gradual adhesion buildup
- High shear strength
- High-temperature resistance
- Excellent solvent resistance
- Excellent UV resistance
- Excellent durability
Where do you find acrylic adhesive: On backings made of Polyester, Foils, Teflon, Tedlar, Kaptons, and other Polypropylene single side tapes. Acrylic adhesives are best to use when you want long- term holding, high temperature, and extreme exposure to conditions. Consider double-coated tapes when you need high holding power and adhesion to a wide variety of substrate surfaces.
Now that you have identified the characteristics of each adhesive option, you can make an informed decision when it comes to determining which adhesive will optimize end-use performance and production value. The decision comes down to comparing the flexibility of the adhesive and its reaction to your substrate.
