Elastomers
What are Elastomers?
Elastomers are plastics that behave rubber-elastically at room temperature and return to their original shape after deformation. These materials show excellent stretchability and flexibility, making them ideal substrates for special adhesive applications.
Properties of Elastomers
- High elastic elongation (up to 1000%)
- Good recovery force after deformation
- Temperature resistance depending on type
- Chemical resistance to various media
- Low surface energy complicates bonding
- Aging resistance varies by material
Elastomer Types
- Natural rubber (NR): High elasticity and tear strength
- EPDM: Excellent weather and ozone resistance
- Silicone: Outstanding temperature resistance
- Polyurethane: High abrasion resistance and strength
Bonding Challenges
- Low surface tension complicates wetting
- Special pressure sensitive adhesives required
- Surface pretreatment often necessary
- Primer systems for improved adhesion
Applications
- Automotive industry: Seals and hoses
- Electric Motor Adhesive: Insulation and damping
- Medical technology: Flexible connections and seals
- Mechanical engineering: Vibration dampers and couplings
