Abstract
A retaining device including a base and a plurality of retaining elements, the retaining device including a first thermoplastic material whose flexural modulus is between 200 and 4500 MPa and a second material selected from the group consisting of a second thermoplastic material whose flexural modulus is different by at least 10% and/or at least 100 MPa from the flexural modulus of the first thermoplastic material, a non-thermoplastic material present at a content strictly greater than 1% by mass of the total composition of the retaining device, a mineral and/or vegetable filler whose content is less than or equal to 30% by mass of the total composition of the retaining device, or a combination thereof.
Claims19
A retaining device, comprising:
- a base extending in a longitudinal direction having an upper face and a lower face,
- a plurality of retaining elements extending from the upper face of the base, each retaining element comprising a rod,
- the retaining device comprising predominantly, in mass percentage, in particular consisting in that it is formed from a first thermoplastic material having a flexural modulus, measured according to standard ISO 178:2019, greater than or equal to 200 MPa and less than or equal to 4500 MPa and a second material, the second material being chosen from the group consisting of:
- a second thermoplastic material having a flexural modulus different by at least 10% and/or at least 100 MPa from the flexural modulus of the first thermoplastic material,
- of a non-thermoplastic material present at a content strictly greater than 1% by mass of the total composition of the retaining device,
- a vegetable filler whose content is less than or equal to 30% by mass of the total composition of the retaining device, or
- a combination thereof.
