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 MF10005. The processing conditions applied here are summarized in Table 1.

[0068] The applied PPS material is commercially available PPS0205.

[0069] MF10005 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 provide polymer composites and structural components produced using them, said polymer composites have improved properties with respect to conventional PTFE on the one hand and other high-performance polymers on the other hand , it is proposed that the polymer compound comprises a portion of a perfluorothermoplastic polymer material and a portion of at least one other different high-performance polymer selected from the group consisting of polyphenylene sulfide (PPS), Polyphenylsulfone (PPSO2), polyamide (PA), polyimide (PI), polyamide-imide (PAI), polyetherimide (PEI) and copolymers of said polymers and copolymers and derivatives, wherein the composite has a homogeneous distribution of polymer fractions and polymer material fractions.

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...
