Abstract
This invention relates to resilient product including a relatively soft workding section (2) secured to a surface of a relatively hard interlayer (4). An opposed surface of the interlayer (4) includes a mounting section (3) which functions to secure the resilient product to a support. The resilient product is particularly suitable for providing a sealing member or a resilient mounting member. The ability of the resilient product to be secured to a support, and remain secured to that support is a particular advantage.
Claims27
A resilient product including a working section formed of a relatively soft thermoplastic elastomeric material, a mounting section having an adhesive surface for securing the working section to a support, and an interlayer being an independent component from the mounting section and the working section and being formed of a relatively hard polymer interposed between the working section and the mounting section and being secured to both said working section and said mounting section, wherein the interlayer is secured to the working section by fusion welding, and the mounting section is attached to the interlayer by adhesion.
A method of producing a resilient product including the following steps:
- bringing an adhesive surface of a mounting section into engagement with one surface of a relatively hard interlayer,
- securing the mounting section to the interlayer by adhesion,
- applying a compressional force to said mounting section interlayer composite,
- feeding the mounting section interlayer composite into the path of molten material intended to form a relatively soft working section, and
- fusing the working section to an opposed surface of the interlayer.
A resilient product adapted to seal a vehicle door to a vehicle body, the resilient product comprising:
- a working section formed of a relatively soft elastomeric material;
- a mounting section having an adhesive for securing the working section to a support;
- and
- an interlayer formed of a relatively hard material interposed between the working section and the mounting section and being further secured to both said working section and said mounting section, the interlayer being fusion welded to the working section.
