Embodiment Construction

[0066] Examples 1 to 3

[0067] During the thermoplastic compounding process, the mixture of PPS and Compound according to the invention made of m-PTFE of type MF 10005. The processing conditions applied here are summarized in Table 1.

[0068] The applied PPS material is commercially available PPS 0205.

[0069] MF 10005 is an m-PTFE polymer modified with PPVE having a comonomer content of 1.7% by weight. The melt flow rate MFR (372 / 5) was 5 g / 10 min.

Abstract

In order to make available polymer compounds that are improved with respect to their properties compared to conventional PTFE, on the one hand, and the further high-performance polymer or polymers, on the other, it is proposed that a polymer compound has a proportion of a fully fluorinated thermoplastic polymer material as well as a proportion of at least one further high-performance polymer different therefrom, selected from the group of polyphenylene sulphide (PPS), polyphenylene sulphone (PPSO2), polyamide (PA), polyimide (PI), polyamide-imide (PAD, and polyether imide (PEI) as well as copolymers and derivatives of these polymers and copolymers, wherein the compound has a homogeneous distribution of the proportions of the polymers and the polymer material.

Description

technical field [0001] The present invention relates to a novel polymer compound comprising a perfluorothermoplastic material, in particular melt-processable polytetrafluoroethylene (PTFE) (m-PTFE), and at least one other material different therefrom The share of high-performance polymers selected from polyphenylene sulfide (PPS), polyphenylene sulfone (PPSO 2 ), polyamide (PA), polyimide (PI), polyamide-imide (PAI), polyetherimide (PEI) and copolymers and derivatives of said polymers and copolymers, wherein , the composite has a homogeneous distribution of polymer fractions. Background technique [0002] The use of conventional or standard PTFE in compounds with the various high performance polymers mentioned above is well known. The composites are produced by mixing different powdery polymers and, depending on the type of main constituent, by subsequent press sintering or extrusion. When PTFE is the main component, the proportion of other high-performance polymers is ge...
