Definitions
- the present invention relates to a combination of at least one fluoropolymer with at least one thermoplastic elastomer.
- TPEs Thermoplastic elastomers
- thermoplastic elastomers require fewer steps than that of rubbers.
- the manufacturing time of thermoplastic elastomers is shorter.
- shape of the parts that can be obtained with thermoplastic elastomers is very varied, unlike conventional rubbers which cannot be blown or thermoformed for example.
- thermoplastic elastomers have the additional advantage of not being vulcanized, unlike rubbers, which means that their manufacturing waste can be easily recycled.
- thermoplastic elastomers suffer from low chemical inertness and limited resistance to soiling, which restricts the application of these compounds especially in the pharmaceutical, food, and household and consumer goods industries.
- Fluoroelastomers such as copolymers of vinylidene fluoride and hexafluoropropylene, exhibit improved chemical resistance properties compared to thermoplastic elastomers.
- FKMs Fluoroelastomers
- their implementation is complex. Indeed, these compounds are in the form of blocks, which must first be calendared before transforming them by pressing into the desired shape.
- a crosslinking process must be applied, this is triggered during pressing but then requires annealing to complete. This process is therefore long and expensive and induces many losses which cannot be recycled. Therefore, there is a need for thermoplastic composites which are both flexible and elastic and have improved chemical resistance and soil resistance which must be met.
- the present invention results from the unexpected demonstration, by the inventors, that a combination of a thermoplastic elastomer and a random copolymer of vinylidene fluoride and hexafluoropropylene leads to products combining good properties of flexibility and d elasticity and high resistance to chemicals and dirt.
- the present invention relates to a combination of polymers comprising:
- thermoplastic elastomer comprising at least 10% by mass of flexible ester blocks relative to the total mass of the thermoplastic elastomer

- the present invention also relates to a composition comprising the combination as defined above.
- the present invention also relates to an article formed from the combination as defined above or from the composition as defined above.
- Elongation at break or percent elongation is a dimensionless characteristic of the materials. It defines the ability of a material to stretch before breaking when it is under tension. The elongation at break is determined by a tensile test according to ISO 527 IA.
- Plastic shrinkage is the ability of a body to return to its normal state after a rise in temperature and / or plastic deformation. Shrinkage refers more particularly to the processes which lead to a reduction in the dimensions of a molded part during its shaping (designated by the term “immediate shrinkage”) and after its shaping (“deferred shrinkage”). In the case of a molding, the plastic shrinkage can be defined as the difference in percentage (%) between the dimension of the final part and the dimension of the mold.
