Definitions
- the invention relates to a composition that has been obtained by the melt-process recycling of one or more multi-layer articles, where the multi-layer articles are composed of at least one melt-processible fluoropolymer layer.
- the composition of the invention is a compatible blend of the different layers from the multi-layer articles.
- the other layers of the multi-layer articles are also melt-processible, and include one or more layers chosen from: a) a melt-processible fluoropolymer of a different composition, b) a non-fluoropolymer, and c) a barrier layer.
- the composition is useful for forming an article in a melt-process operation.
- the composition may be used by itself, may be blended with other virgin or recycled materials, or may be used at low levels with melt-processible polymers as a process aid.
- Compatibility in the polymer adhesion context is represented by low interfacial tension.
- the polar component of the surface tension plays a major role in the peeling strength and the work of adhesion between polymers.
- the greater the polarity difference the greater will be the interfacial tension.
- other factors such as processing parameters and tooling design can affect the peeling strength.
- multilayer structures in which the layers adhere well, have the excellent properties for use in high purity applications, and are capable of being recycled.
- One additional advantage of recycling the multilayer structures of the invention is that fluoropolymers, and other polymers used in these types of structures, can be relatively expensive materials, and the articles formed from the recycled blend can receive a performance benefit from the special properties of the fluoropolymer and other high-performance recycled polymer layers.
- the invention relates to a melt processible polymer composition having a compatible melt blend formed from one or more recycled multi-layer articles having at least one melt-processible fluoropolymer layer.
- multi-layer article an article, film or sheet having two or more layers.
- the article may consist of 2, 3, 4, 5, 6 or more layers adhered together.
- Tie layers and adhesive layers may be part of the structure, or the different layers may adhere together without tie-layers or adhesives.
- fluoromonomer or the expression “fluorinated monomer” means a polymerizable alkene which contains at least one fluorine atom, fluoroalkyl group, or fluoroalkoxy group attached to the double bond of the alkene that undergoes polymerization.
- fluoropolymer means a polymer formed by the polymerization of at least one fluoromonomer, and it is inclusive of homopolymers, copolymers, terpolymers and higher polymers which are thermoplastic in their nature, meaning they are capable of being formed into useful pieces by flowing upon the application of heat, such as is done in molding and extrusion processes. Fluoropolymers useful in the present invention are those that are melt processable.
- Copolymers, terpolymers and higher polymers of vinylidene fluoride may be made by reacting vinylidene fluoride with one or more monomers from the group consisting of vinyl fluoride, trifluoroethene, tetrafluoroethene, one or more of partly or fully fluorinated alpha-olefins such as 3,3,3-trifluoro-1-propene, 1,2,3,3,3-pentafluoropropene, 3,3,3,4,4-pentafluoro-1-butene, and hexafluoropropene, the partly fluorinated olefin hexafluoroisobutylene, perfluorinated vinyl ethers, such as perfluoromethyl vinyl ether, perfluoroethyl vinyl ether, perfluoro-n-propyl vinyl ether, and perfluoro-2-propoxypropyl vinyl ether, fluorinated dioxides, such as perfluoro(
- the multi-layer structure may contain at least one barrier layer.
- barrier layers include, but are not limited to ethylene vinyl alcohol (EVOH) and poly(vinyl alcohol) which is fully or partially hydrolyzed polyvinyl acetate.
- EVOH ethylene vinyl alcohol
- the barrier layer is preferably present in films, reactors, bags, and other multi-layer structures to improve permeation resistance to CO 2 , O 2 , H 2 O, and other substances.
- Multi-layer tubing, especially very flexible tubing such as that used in peristolic pumps, may have no extra barrier layer present.
- films used in the invention, and formed into articles such as bags contain from 2 to 5 or more layers.
- the overall thickness of the film is from 1 to 40 mils and preferably from 3 to 15 mils.
- a bag is made of a PVDF/TPU/EVOH/TPU/PVDF composition, having a high purity fluoropolymer with low surface tension on the inner layer, the bulk of the structure's volume being TPU with good flexibility and toughness and also acts as a tie-layer between the PVDF and EVOH.
- the TPU is ester based without lubricants.
- a manufacturing system having a multi-layer bag of PVDF/TPU/EVOH/TPU/PVDF, plus multi-layer tubing, and single composition stirrers and connectors is recycles into a melt blend.
- the weight percentage of each component is 10 to 100, and preferably 25 to 70 weight percent of PVDF; 0 to 90 and preferably 30-70 weight percent TPU; and 0 to 40 weight percent and preferably 5 to 25 weight percent of EVOH. From 1 to 60 weight percent and preferably 15 to 30 weight percent based on the total composition of a compatibilizer, such as KYNAR ADX polymer (a maleic anhydride modified PVDF) could be added to the melt blend before being formed into a final article.
- a compatibilizer such as KYNAR ADX polymer (a maleic anhydride modified PVDF) could be added to the melt blend before being formed into a final article.
- KYNAR ADX polymer can have from 0.1% to 30% and preferably from 0.5% to 10% weight percent of maleic anhydride graft or content.
- a blend of these three materials in the above range has good melt processing and melt strength behavior and can easily be converted to films and tubes or injection molded parts.
- the morphology of the blend exhibits interesting properties.
- EVOH and PVDF exist as separate dispersed domains.
- the size of the PVDF particles will be at least an order of magnitude larger than the EVOH domains. Small domains of TPU can be seen inside the PVDF region in higher magnifications.
- FIG. 1 shows a micrograph of a 30/60/10 blend of PVDF/TPU/EVOH on weight basis.
- the film was ground down to 1 ⁇ 8′′ flakes. Per weight basis the blend has approximately 62% KYNAR 2800, 30% ELASTOLLAN C85A10 (from BASF), and 8% EVALCA H171b (from Kuraray). These flakes were then pelletized on a 18 mm Leistritz co-rotating twin screw extruder. The screw used was specially designed for intensive mixing. The KYNAR 2800 based multi-layer film pelletized very easily. The pellets were then dried at 60° C. for a minimum of 2 hours in a vacuum drier. After drying, the pellets were injection molded into ASTM D 638 Type I and IV tensile bars. The bars were tested for tensile and elongation following ASTM D 639.
- Type I bars were converted to ASTM D 265 impact bars. The bars were notched and tested at ⁇ 40° C. and ⁇ 60° C. in accordance with ASTM D 265 notched impact. Table 2 illustrates the tensile, elongation, and impact physical properties
- Multilayer films were extruded with three different materials having a five-layer construction. This construction is KYNAR 2500 based. Table 8, below, describes the film.
- the next step in the evaluation is to make film on a three roll stack cast film line. Making quality film was not possible. The blend lacked melt strength and would tear very easily. Severe gross phase separation and plate out was also observed during the process.
- the first film was a multilayer film of weight percent and thickness shown below and the second film was a single layer film having identical weight percents of the contents in the multilayer.
- the multilayer film is transparent; the melt blended film is opaque. Pelletization of the blend and manufacturing of the blended film was performed without any processing issues. Below is a description of the structure.
